Under what circumstances will a car starter fail?
2 Answers
There are many reasons for car starter damage, such as reaching the end of its lifespan, improper operation, or even traffic accidents that can lead to such situations. Below is a relevant introduction: 1. Car Starter: The starter converts the electrical energy from the battery into mechanical energy, driving the engine flywheel to rotate and enabling the engine to start. Before the engine can operate under its own power, it must be rotated by an external force. The process of transitioning the engine from a stationary state to self-sustained operation with the help of external force is called engine starting. 2. Working Principle: Its working principle is based on the energy conversion process related to Ampere's Law encountered in middle school physics, where a current-carrying conductor experiences force in a magnetic field. The motor includes essential components such as the armature, commutator, magnetic poles, brushes, bearings, and housing.
Starter failure is quite common, and I've encountered it several times. The main issues are burnt-out coils or severely worn gears. Problems are especially frequent in winter when low temperatures thicken the engine oil, increasing starting resistance and forcing the starter to work overtime. A weak battery is also troublesome - insufficient voltage causes the starter to spin uselessly, making a coughing-like clicking sound. In rainy areas, extra caution is needed as water ingress can rust the starter motor. Another detail is excessive starting frequency - some people repeatedly turn the key when the engine won't start, but it's better to wait about ten seconds between attempts. Starter repairs aren't cheap, so proper maintenance can save significant money.
