eelkäivitusmootor

Eelkäivitusmootor, often translated as starter motor, is an electric motor that is used to turn or crank an internal combustion engine to start it. It is a critical component of every gasoline or diesel powered vehicle. The starter motor receives a large surge of electrical current from the battery, which generates a magnetic field. This magnetic field causes the motor's armature to rotate. Attached to the armature is a small gear, called a pinion gear. When the starter motor is activated, the pinion gear engages with a larger gear on the engine's flywheel. This meshing allows the starter motor to turn the engine's crankshaft. Once the internal combustion engine starts running on its own, the starter motor is disengaged, and the pinion gear retracts from the flywheel. Starter motors are typically designed for short bursts of operation, as prolonged use can overheat and damage them. The power requirements for starting an engine are substantial, which is why a fully charged battery is essential for proper starter motor function. Various types of starter motors exist, but the most common is the direct-drive starter, which uses a reduction gear to increase torque.
