it consists of a series of resistances, a magnet and a bar that is pulled by the magnet. Initially all the resistance comes in series so the current is limited. when the bar is pulled towards the magnet slowly the resistance decreases and the current increases. thus it protects the DC motor from initial high current.

Which of these is needed to operate on an electric motor?
alternating current
What size of electric motor that requires wye delta starter?
10 hp and above motor power rating....
Why the armature rheostat of dc is motor kept at maximum resistance position?
It isn't. It is only kept at maximum resistance when the motor is not running. That is done to limit the starting current.
Why you use DOL starter in starting of motor?
because of starting current of induction motor is very high and it damages the insulation of motor
What is the difference between electricmotor and generator?
An electric motor is an AC motor which works with alternating current But Generator is D. C motor that works under the principle of direct current
What is celinoid?
The starter solenoid receives a large electric current from the car battery and a small electric current from the ignition switch. When the ignition switch is turned on, a small electric current is sent to the starter solenoid. This causes the starter solenoid to close a pair of heavy contacts, thus relaying a large electric current to the starter motor, which in turn sets the engine in motion.
Function of the starter for the slip ring motor?
to limit the induced current in the rotor to assist with high inertia loads
Is a starter solenoid part of the ignition system?
The starter solenoid, despite its name, is not part of a vehicle's ignition system. It is used to send electric current to the starter motor, engaging the engine.
What is startermoter?
A starter moter is a high-torque electric motor for turning the gear on the engine flywheel. The modern starter motor is either a permanent-magnet or a Series-parallel wound Direct current electric moter with a solenoid switch (similar to a relay) mounted on it.
What allows the current to enter the electronromagnet in an electric motor?
The resistor allows current to enter the electromagnet in an electric motor. The resistor regulates the amount of current that enters the electric motor.
Is four point starter is applicable to compound motor?
Yes! · To accelerate the motor to the rated speed · To limit the starting current in the armature to a safe value · To disconnect the motor in case of a supply failure or overload
What is a motor housing?
The outer casing of an electric motor, as in a starter, wiper motor etc.
What is motor housing?
The outer casing of an electric motor, as in a starter, wiper motor etc.
Why DOL starter using to start motor?
Yes up to certain rating and application a motor can be started on DOL. Beyond a rating different methods need to be used to limit the starting current.
How does a motorcycle starter motor work?
When you hit the starter button the starter relay send power to the starter. the starter solenoid pushes the starter shaft outward and the starter turns. When the solenoid moves the shaft it is connected to the jackshaft which ingages the starter gear on the clutch
Where on a motor vehicle would brass be used?
Brass bushings inside the electric starter motor.
What parts make up a starter motor?
Modern starters include: * the starter motor... a motor * the solenoid, which engages the electrical current to the starter AND engages the gear to the flywheel. * the bendix, which is a gear that engages the starter to the flywheel.
