However, the induction motors of high power require a suitable device for starting because they take an excessive amount of starting current. Therefore, to avoid the motor from burnout and heating due to the high value of starting current, various types of starters are used for starting induction motors.

Direct ON Line starter is the simplest kind of starter that connects the motor directly to the power supply through a three-phase contactor. An Electromagnetically operated contactor is used which can be opened by thermal overload relay whenever a fault condition occurs. Contactors are typically going to be controlled by separate start and stop buttons, and there is also an additional contact on the contactor is employed across the start button as a hold in contact.

For example, the contactor used is electrically latched based and closed whereas the motor is working. Overcurrent faults occur mostly and mainly due to ground faults and short circuit faults. Therefore, fuses and circuit breakers are used that show quick response towards fault when such type of fault large current passes from the system. When the amount of current larger than the rated current of the device passed through the system such devices operates and open the circuit until the fault is removed from the system.

If the overload current persists for a long span of time then things and machines get damaged. Overcurrent protection rating is always selected with so much care that it must provide enough protection against high current and also it must allow enough current without operating the overcurrent protection for the motor to operate under heavy mechanical load. Whenever motor draws too much amount of current to fulfill the load demand and if load demand goes beyond the allowable limit, such condition or situation is called as Overload.

Therefore, aak plant benefits protection is used in it.

It is basically a type of safety protection when the motor draws too much current or overload current and causing the overheating of the electrical machine. Sometimes motor starters come with built-in overload relay. Overload relays are classified on the base of different tripping classes. Tripping class is a term used in overload relay designing which means how much seconds an overload relay takes to trip. Overload protections are provided with the help of an overload relay.

For starting the motor, we press Green Button and the contact is closed and therefore full line voltage start appearing across the motor. Contactor can either consist of 3 poles or 4-pole depend upon the design. In our case, the contactor used is of 4-pole type.

The additional coil gets de-energized if there is any fault occur and then starter disconnects the motor from supply mains. The connection of contactor can be done among relay coil, supply voltage as well as thermal overload. Between the mains supply terminals and motor terminals the DOL starter main terminals are connected and with the two terminals of the three-phase power supply as described in figure 1 the control circuit is energized. Contactor coil gets energized due to this current that makes to close the contacts of the contactor and in the result of this three-phase supply is connected to the motor.

The start button is sometimes called as push button because when this button is released the control circuit of DOL starter still provide the power supply via Hold-On-Contact. The current path via contactor coil will break when the stop button is pressed and due to this the contactor contacts drop out, thus breaking the power supply to the motor.

We can also say that the overload relay coil operates. More the load current more is the heating effect.To interconnect the motor circuit in such a way, in which the second motor will not start until the first one run likewise the third one motor will not run unless the second one run and so on. This kind of motor circuit connection is called interlocking. And motor M1 Starts to run. When m1 energies, the normally open NO link will be closed immediately, which is in parallel with ON-Push 1.

This is called Holding link i. Now, Motor will still run even we leave disconnect to stop the ON-Push 1. A normally open NO link is also used in line 2. Now, if we press ON-Push 2, then second motor M2 will be also started to run, in addition, the normally open NO links of the connected contactor M2 in the circuit would be also closed immediately. This way, Motor 2 will start to run. Note that Motor 2 will not start to run until Motor 1 runs, i. Likewise, Motor 3 will not start until motor 2 runs, i.

In each control circuit, control fuse, and overload relays are connected for short circuit and overload protection respectively.

This is a simple electrical interlocking circuit. Lots of circuits similar to this interlocking circuit are used in industries. The circuit interlocking depends on the nature of working and task which is to be done by motors. So we may use and make any kind of interlocking circuits for any purpose very easily.

In short, we may change the motors operation and control by doing some modification in the above simple electrical interlocking control circuit diagram. This way, when Contactor M3 energizes, and motor 3 starts to run, then the normally close NC link of Motor 1 connected in line 1 will open immediately after energizing the M3 Contactor which cause to de-energize the M1 contactor, hence, Motor M1 will stop. We may also configure the above electrical interlocking control circuit with little modification for star and run each motor individually.

A motor starter is a combination of devices used to start, run, and stop an AC induction motor based on commands from an operator or a controller. Several other combinations are possible in North America and other countries and are easily derived from the methods shown in this document.

The motor starter must have at least two components to operate: a contactor to open or close the flow of energy to the motor, and an overload relay to protect the motor against thermal overload.

Other devices for disconnecting and short-circuit protection may be needed, typically a circuit breaker or fuses. Short-circuit protection will not be shown in the examples that follow. A contactor is a 3-pole electromechanical switch whose contacts are closed by applying a voltage to its coil. The contactor is specifically designed for motor control but can be used for other purposes such as resistive and lighting loads.

Since a motor has inductance, the breaking of the current is more difficult so designers must adhere to both a horsepower and current rating when specifying the size of the contactor. The overload relay is a device that has three current sensing elements and protects the motor from an overcurrent. Each phase going from the contactor to the motor passes through these current sensing elements. The overload relay has a selectable current setting based on the full load amp rating of the motor.

If the overload current exceeds the setting of the relay for a sufficient length of time, a set of contacts opens to protect the motor from damage.

This article shows how to wire various motors using the Fuji series of contactors sold by AutomationDirect. Other brands of contactors may be wired the same or similarly. You must supply a disconnect switch, proper sized wire, enclosures, terminal blocks and any other devices needed to complete your circuit.

Follow the instructions supplied for each specific device. Failure to do so may result in electrical shock or damage. The following diagram depicts 3-phase non-reversing motor control with 24 VDC control voltage and manual operation. We will use a contactor, an auxiliary contact block, an overload relay, a normally open start pushbutton, a normally closed stop pushbutton, and a power supply with a fuse.

The start and stop circuits can also be controlled using PLC inputs and outputs. This diagram is for 3-phase reversing motor control with 24 VDC control voltage. It uses two contactors, two auxiliary contact blocks, an overload relay, a mechanical interlock, two normally open start pushbuttons, a normally closed stop pushbutton, and a power supply with a fuse.

The forward, reverse, and stop circuits could alternatively be controlled using a PLC. Note that Reversing Kits for both the load and line side of the contactors may be available and may simplify the process of wiring a reversing contactor.

This diagram is for single-phase motor control. It uses a contactor, an overload relay, one auxiliary contact block, a normally open start pushbutton, a normally closed stop pushbutton, and a power supply with a fuse. The start and stop circuits could alternatively be controlled using a PLC. The following diagram is shown for 3-phase motor control of a delta-star connection.

Ebay is a good place to look, also your local auto electrician is worth a phone call. Tools required 1. A faulty starter motor can sound like a flat battery, the engine turns over slowly or not at all, sometimes you can see the battery terminals and leads smoke or get hot due to the high currents been drawn by the faulty starter.

First thing, check for other faults. The best way to check the battery is with a load tester but these are expensive, and there are ways around it. Put a volt meter on the battery, it should read, around If it is as low as Check battery cables are clean and tight and in good condition. If the fault moved to the other vehicle, then you have a problem with your battery, Charge it or replace it.

Motor Starters :Types of starter, Working of starter and it’s circuit diagram

If you have eliminated everything else chances are that the starter is faulty. On page 14 of this instuctable there is a guide to testing the starter motor, this can be done on the car, if you can get to the back of the starter. This can be helpful if the starter is completely dead, not clicking or anything and can help diagnosis a wiring issues with the vehicle or a dead solenoid. Some vehicles it is easier and quicker to remove items that are in the way, rather than try and work around them.

On many vehicles you should do this while the starter is still bolted on. Now that you have it out find a clean work area and a container to put all the bits into. Thoroughly do a visual inspection of the field windings, and armature for any burnt or broken insulation, broken wires corrosion or other damage. Also check the commutator on the armature for broken or missing segments If these parts are damaged it may be cheaper to replace the whole starter motor.

The pinion gear and solenoid can also be checked for wear or damage. This starter was quite corroded in places due to the recent flood we have had here, the brushes and bushes are worn, but the rest appears to be in reasonable condition. Remove any corrosion with wet and dry sand paper, and the commutator can be sanded and the back of a box cutter knife can be used to clean out between the segments. The insulation between the segments should be under cut to work correctly.

Than an oily rag is used to wipe everything to help prevent any future corrosion. The bushes can be removed with socket and a hammer. A little heat on the alloy nose will help remove the bush. This is not to difficult just put it on your finger and fill with engine oil then place your thumb on top and squeeze.

Do this 2 or 3 times until you can see the oil coming out the sides of the bush. This step can be tricky, and if you have access to a press then use it, as you a much less likely to damage the bushes.Three phase systems are extremely common in industrial and commercial settings. They can also be found in large residential complexes and appliances requiring a large amount of power.

Although these systems may seem intimidating at first, a walkthrough on 3 phase wiring for dummies will help clarify the whole situation. Different regions may use different voltages, frequencies, and requirements when it comes to electrical power systems. However, they all agree on the fact that three phases are the optimal number to bring the largest amount of power at the lowest number of conductors. It is thus very important to know how to work and be capable of troubleshooting different systems which require these connections.

When we talk about three phases, we are always inferring that we are working with Alternating Current AC. The electrical term AC simply means that the current will alternate the direction of the flow. The frequency of the current will determine the number of times the flow will be alternated per second.

AC is found in house outlets and used for most appliances in your home. Any appliance will have a number of parameters related to its electrical properties. These parameters are Voltage, Current and Power. Voltage can be taught of as the available pressure of electricity. A typical home will provide or volts depending on where you live. Current is measured in amps and is the rate of flow of electrons within a conductor.

The amount of current required will depend on the appliance. Depending on the source, this system may also have a neutral wire for returning current back to the transformer.

The most common use of three-phase power is for motors. It provides a unique feature which is a rotating field in order to rotate the motor without the need of a starter circuit. This is accomplished due to the fact that each one of the three phases has a different offset.

In simple terms, the current is being alternated during a different time.All wiring diagrams posted on the site are collected from free sources and are intended solely for informational purposes. Chrysler Wiring Diagrams. Chrysler Voyager 2. EWD Chrysler Voyager from of release.

There are three main components in the switch starting circuit: ignition switchstarter solenoidstarter relay. Usually, the ignition switch connects with a key or a button, and inside of it has the regular wire connects to the car battery.

When the ignition switch is turned or pressed the button to start position, there will be a small current flow through the starter solenoid coil, allow sufficient current flow to the starter.

Expect to take part in starting control circuit, the ignition switch also has other functions, such as lock the steering wheel, connected to car electrical system, and connected to the vehicle computer fault diagnosis. The starter solenoid is the main part of the control starter circuit, including the with relay type and non-relay type.

The solenoid switch is composed of a solenoid, which is an electromagnetic device that produces the attraction or retention of the moving core.

Most of the starter solenoid is fixed directly to the top of the starter. The starter relay is another switch that is used to control the starting circuit. In the start control circuit, the relay is connected in series with the battery to shorten the transmission of the large current cable length.

In mini cars equipped with small power starter, the ignition switch start position is used to control the starter solenoid switch directly, as shown in the picture below. When large power starter is equipped, in order to reduce intensity of the current that passes through the ignition switch and avoid ablation of the switch, the start relay is often used to control the heavy current of the starter solenoid switch, and the ignition switch Start position is used to control the low current of the relay coil.

The single relay controlled starter solenoid wiring diagram is as shown in the following picture. The automatic transmission equips with neutral starting switch, which is in series connection to the bonding terminal of the start relay coil.

Neutral starting switch is on only in the case that the automatic transmission gear lever is in parking position P and neutral position N. In other gears, the switch is in an off state, so as to avoid damages to machine parts caused by misoperation.

To ensure that the starter can stall automatically and the starter circuit not connected after the engine starts, some cars adopt the compound relay circuit with safety driving protection. Before the engine starts, the alternator does not generate electricity, the voltage of the neutral tap N binding post is zero, no current passes through the charge light relay, Starter relay coil and charging indicator relay contacts are connected to ground.

After the engine starts, the neutral tap N terminal post of the car alternator outputs proper voltage, which acts on the charge light relay coil and cut-off the current of the starter relay. At this point, even if the ignition switch key not loosened timely, or the key is incorrectly rotated to the ST position again, the starter will not operate. Ignition Switch Usually, the ignition switch connects with a key or a button, and inside of it has the regular wire connects to the car battery.

Starter Solenoid The starter solenoid is the main part of the control starter circuit, including the with relay type and non-relay type. Starter Relay The starter relay is another switch that is used to control the starting circuit.
