Sine Wave Control of Brushless DC Motor

11-21

        The traditional brushless DC motor adopts a square wave control method, which is simple to control and easy to implement. At the same time, there are problems such as torque ripple and commutation noise, and there are limitations in some applications that require noise. For these applications, the use of sine wave control can solve this problem well.          Introduction to Sine Wave Control of Brushless DC Motor        The sine wave control of the DC brushless motor is to apply a certain voltage to the motor winding to generate a sinusoida

Talking about the basic functions of the controller

       Data buffering: Because the speed of the I/O device is low and the speed of the CPU and memory is very high, a buffer must be set in the controller. When outputting, use this buffer to temporarily store data from the host at high speed, and then transfer the data in the buffer to the I/O device at the rate that the I/O device has; when inputting, the buffer is used To temporarily store the data sent from the I/O device, after receiving a batch of data, the data in the buffer is transmitted to the host at a high speed.        Error control: The device controller is also respons
