The gear shift adjustment plate can be selectively connected to the reading circuit or connected to both of them. For example, after the reading circuit reads the motor parameters, it adjusts and modifies the drive circuit. After writing the modified adjustment data into the first storage module, the reading circuit can be detached, and then the gear shift adjustment plate can be installed to adjust the gear of the drive circuit.

[0016] It also includes a gear shift adjustment plate 3, which includes an adjustment circuit and is detachably connected to the drive circuit.

[0020] In the control unit U11, taking speed as an example, the time interval between two current waveforms in the same phase is detected to calculate the motor speed, and then compared with the set speed. After comparison, there are three possibilities: 1. The value is positive, which means the speed is too fast and needs to be reduced; 2. The value is negative, which means the speed is too slow and needs to be accelerated; 3. The value is zero, which means the speed is just right and no action is needed.

[0021] This includes a reading circuit board 2, the reading circuit being disposed on the reading circuit board 2, and a driving circuit board 1, the driving circuit being disposed on the driving circuit board 1, and a second connector J11 electrically connected to the driving circuit being mounted on the driving circuit board 1.
