We use drv11873 to control the brushless motor. When the motor starts up, the motor will shake violently. After the motor starts up, the speed will be normal.We need your help to analyz this problem.In the green frame, the speed feedback of the motor can be read at the moment when the motor starts. After the motor starts shaking, it will normally enter the operation mode.
2.We find the following description in the datasheet;
But compared to other products that use drv11873, our startup time is longer;We want to find a corresponding debugging method to improve this problem.
Thank you very much
