how starter motors work

The video tutorial explains the operation of a solenoid coil in a starter motor. It covers the roles of the pulling and holding coils, the flow of electricity, and the creation of a magnetic field. The interaction between the electromagnetic field and the rotor is detailed, leading to the rotation of the flywheel. The process of transitioning from the starter motor to the engine is also explained, including the role of the alternator in recharging the battery.

What is the primary function of the pulling coil in a solenoid?

• To connect the battery to the starter motor

• To create a magnetic field that moves the piston

• To recharge the battery

• To hold the piston in position

How does the current return to the battery in the starter motor system?

• Directly through the battery terminals

• Through the alternator

• Via the frame of the car

• Through the pulling coil

What role does the commutator play in the starter motor?

• It holds the piston in place

• It generates the initial spark for combustion

• It transfers current to the brushes

• It recharges the battery

What happens when the engine starts rotating faster than the starter motor?

• The pinion gear locks in place

• The overrunning clutch unlocks

• The battery stops charging

• The starter motor speeds up

What occurs when the key is released in the ignition system?

• The piston is released and the pinion gear disengages

• The solenoid coil is energized

• The battery stops supplying power

• The starter motor continues to run
