【CW32】【Verified】Hard disk motor driver-402304A

I have uploaded all the source codes for the May training camp as attachments. All copyrights belong to the training camp teachers!

Use the CW32F030C8T6 as the main control hard disk brushless motor driver board, and take advantage of the learning opportunities at Lichuang Training Camp to learn about brushless motor drivers!

The board consists of three parts, the main control board (including the minimum circuit of CW32), the driver board (including gate drive and NMOS circuits), and the motor connection board (used to connect the driver board and hard disk motor)

The circuit is modified based on the official example circuit. There are very few modifications, mainly to simplify the size so that the circuit board can be stuffed into the hard drive case!

The shape of the board is adapted according to the shape of the space after disassembly and the position of the screw holes! (The final hole position is still slightly misaligned. If it can be used normally, there is no need to redo the board!)

The program files in the attachment are compiled directly from the official source files. I am not good at writing code and can only copy it!

The hard drive motor is running normally and there is no problem with speed adjustment. I can’t think of anything I would use this hard drive motor for now. If you have suitable fan blades, converting a scrap hard drive into a brushless fan that can be used in summer is also a good choice! ! ~

The following is a wonderful PCB appreciation:
