In order to improve the efficiency and fault diagnosis ability of deep-sea manned submersible's motor and reduce the working noise of the system,the high-efficiency and low-noise drive control technology of brushless DC motor is studied.The brushless DC motor driver was designed by using a 3-phase full-wave sine wave control chip with intelligent phase control function,combined with an intelligent power module(IPM).TB6605,The MCU is used to detect the voltage,current,temperature,speed and position information of the system,providing the necessary information feedback for the control system,and playing a real-time monitoring function for the system status of the brushless DC motor.The experiment-al results show that the driver developed in this paper has high working efficiency in the full speed range of the motor,the ef-ficiency of the rated working condition point is as high as 90％,and in the full speed range,the smoothness of the motor op-eration is improved and the system noise is reduced.The research has a good supporting effect on improving the working ef-ficiency and fault diagnosis ability of the deep-sea manned submersible motor,and reducing the working noise of the system.
