Description

technical field [0001] The invention relates to the technical field of motors, in particular to an electric vehicle motor controller assembly with a safety alarm function. Background technique [0002] In electric vehicles, the function of the motor controller is to convert the electric energy stored in the power battery into the electric energy required to drive the motor according to the gear position, accelerator and brake instructions, so as to control the starting operation, forward and backward speed and climbing of the electric vehicle. It may help the electric vehicle to brake and store part of the braking energy in the power battery. [0003] The motor controller plays an important role in electric vehicles. For this, a motor controller is proposed in the Chinese patent CN105578838B. A cooling water channel is opened on the radiator and a water inlet and a water outlet connected to the cooling water channel are provided. The cooling water channel Heat dissipation f...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an electric vehicle motor controller assembly with a safety alarm function, which has safety alarms, thereby protecting the motor from external force damage or excessive temperature, and increasing the service life of the motor. It solves the problem that there is no safety alarm function, the motor is damaged by external force or the temperature is too high and cannot be protected, which reduces the service life of the motor
