It is fixed on the power device installation platform, and the upper and lower limit stations respectively limit and fix the upper and lower ends of the power device. One side of the control circuit board is inserted into the circuit board card slot for fixing, and the other side is connected and fixed with the power device.

As a further improvement of the technical solution, the pressure plate of the power device is provided with a plurality of pressure plate stress grooves.

The heat dissipation shell of the motor controller described in the utility model adopts an open upper shell and a lower shell butt joint combination, and the power device and the control circuit board are all installed in a bolt-free slot, which is suitable for assembly in an automated production line; both sides of the power device are connected to the heat sink The shells are in close contact, improving heat dissipation. A glue injection groove is set at the connection between the hook groove and the hook, and the waterproof glue is injected, and the waterproof effect is good. Multiple pressure plate stress grooves are set on the pressure plate of the power device, so that each power device is not affected by the fit error, so that each power device is under uniform pressure, which can ensure the heat dissipation effect of the power device and increase the power. The installation stability of devices and control circuit boards.
