How Do Car Starter Motors Work?

Model: (Various brands) Various
Part: Starter motor

In today's article, we will see how the car starter motor works. When the key is inserted into the ignition lock, a signal is sent to the battery, which provides power to the starter motor through the solenoid. When the solenoid receives the electrical signal, it pushes on the electric motor to engage the pinion, which connects to the engine and allows it to reach the necessary RPM for ignition. When the engine starts, the starter motor receives a signal to retract the pinion, allowing the crankshaft to rotate freely.
