Regarding modern engines, people know that they are the power source of machinery, but how to start the engine may not be well understood, mainly through the starter motor. A starter motor is an electric motor device used to start an internal combustion engine or other mechanical equipment. Its main function is to provide sufficient torque to start the engine and achieve the starting operation. Here are some information about the starter motor:
1. Working principle:
The starter motor usually adopts a DC series excited motor, and the rotor and stator parts of this motor are wound with relatively thick rectangular cross-section copper wire. The working principle of a starter motor is based on the force acting on an energized conductor in a magnetic field, known as Ampere's Law, which converts electrical energy into mechanical energy. An electric motor includes components such as armature, commutator, magnetic poles, brushes, bearings, and housing.
2. Composition:
The starter motor consists of three main parts: a DC series excited motor, a transmission mechanism, and a control device. The function of a DC series excited motor is to convert the electrical energy input from the battery into mechanical energy and generate electromagnetic torque. The function of the transmission mechanism (starter clutch, engagement device) is to make the small gear on the starter shaft mesh into the flywheel ring gear when the engine starts, and transmit the torque of the starter to the engine crankshaft; After the engine is started, it can automatically disengage the starter small gear from the flywheel ring gear. The function of the control device (starter switch) is to connect and disconnect the circuit between the motor and the battery.
3. Application:
Starters are widely used in various internal combustion engine vehicles, such as cars, motorcycles, trucks, as well as ships, airplanes, and industrial machinery equipment. In these applications, the starter is a key component that starts the entire mechanical system, ensuring the normal operation of the equipment.
4. Characteristics:
The starter motor can provide sufficient torque to start the internal combustion engine, and can reliably start even under low temperature or high load conditions. It can quickly respond to start commands and quickly bring the engine to normal operating speed to ensure that the vehicle or equipment can start quickly. Starters are usually made of durable materials and designed to withstand frequent starting operations and harsh environments, and have a long service life. Modern starter motors are usually equipped with automatic control functions, which can intelligently adjust according to the load and environmental conditions during the starting process, improving starting efficiency and safety.

Starters are usually made of durable materials and designed to withstand frequent starting operations and harsh environments, and have a long service life. Modern starters are usually equipped with automatic control functions, which can intelligently adjust according to the load situation and environmental conditions during the starting process, improving starting efficiency and safety.
