The starting engine is the core executive component of the automotive engine start-up system. The main function is to convert the electrical energy of the battery into mechanical energy by driving the engine flywheel to move the engine from a stationary state to a working state.
Its core structure is composed of direct current motor, transmission and electromagnetic switch. Direct current motor produces rotating torque by electromagnetic induction. The drive mechanism comprises a one-way clutch and a drive gear, which when started is jointed with the flywheel rings to transfer power and automatically detach after starting; The electromagnetic switch is responsible for controlling the disconnect of the circuit, connecting the battery to the electric motor, and pushing the drive gear to rod.
High-quality starters need to have high torque output, resistance to frequent starts and vibration resistance, and adapt to harsh environments such as low temperatures and high humidity. It directly determines whether the engine can start smoothly, and is the key component of the reliability of the vehicle. It is widely used in all kinds of internal combustion engine driven vehicles.
