Quick Answer: How does the basic electric starter motor work?

When you turn the ignition switch, the electromagnet inside the body engages & pushes out a rod to which the pinion is attached. The pinion meets the flywheel and the starter motor turns. This spins the engine over, sucking in air (as well as fuel).

How does an electric starter work?

Your starter is really an electric motor. It engages when you turn the ignition to “run” and turns the engine over allowing it to suck in air. … When you turn the ignition switch, the starter motor is energized, and the electromagnet inside the body engages. This pushes out a rod to which the pinion gear is attached.

What is the function of starter motor?

A motor starter provides defense by first controlling the electrical output of your device or equipment at its initial point of operation (when you turn it on or it engages). From that point, the starter continues to protect your system, operating as a fail-safe.

How does a starter motor solenoid work?

When the ignition switch is turned on, a small electric current is sent through the starter solenoid. … When low-current power from the starting battery is applied to the starter solenoid, usually through a key-operated switch, the solenoid closes high-current contacts for the starter motor and it starts to run.

What are the parts of starter motor and its function?

The starter converts electrical energy into mechanical energy to start the engine. Two major parts of a starter include an electromagnetic field and a rotating armature. Other significant parts of a starter include a solenoid, shift fork and the starter drive gear.

Can you jump start a car with a bad starter?

Jump-starting a car with a bad starter motor will not help start the engine. Jump-starting will only boost battery power. A manual transmission car with a bad starter may be push or tow started but an auto transmission car can not.
