How they work

A starter is a device that initiates engine operation. Since a vehicle engine cannot start unaided, an external force is required to provide rotational speed at or above a set value. The starter drives a built-in motor using the vehicle battery as a power source to create power and start the engine. Unlike normal DC motors, the starter is only used for a short time (rated at 30 seconds). Thus, the starter is designed to be very small despite producing a large output.
