Problems solved by technology

But this three-ring system also has the obvious disadvantage of slow response to control actions
This will greatly affect the control performance of the motor under limited rotation angle
[0004] The existing brushless DC motor drive controllers generally use analog signals for data transmission, which leads to weak anti-interference ability of the system and adds additional A / D and D / A links
[0005] The existing brushless DC motor drive controller generally has no redundancy structure and the application of redundancy management technology, which greatly affects the safety and reliability of the system
