What is the function of the communication auxiliary motor?

An AC generator is used for power generation, and its main function in a circuit is generally to generate electricity. Auxiliary electric motor refers to the electric motor used on locomotives to drive various auxiliary machinery. Such as ventilation fan motors, air compressor motors, oil pump motors, etc. Usually, DC motors or asynchronous motors are used.

DC电动机通常用于柴油机车，由柴油发动机驱动的直流辅助发电机供电。异步电动机通常用于电力机车，由分裂相机或逆变器供电。

Communication auxiliary motors include ventilation fan motors, air compressor motors, oil pump motors, etc. Usually, DC motors or asynchronous motors are used. DC electric motors are commonly used in diesel locomotives, powered by a DC auxiliary generator driven by a diesel engine. Asynchronous motors are commonly used in electric locomotives, powered by splitting cameras or inverters.
