MOTOR CONTROLLER AND MOTOR COMPRISING THE SAME

摘要

A motor controller including a control box and a control circuit board disposed on the chamber of the control box. A control chip is disposed on the outer edge of the upper surface of the control circuit board. The outer wall of the control box is depressed inward to form a heat dissipation boss. A gap is formed between the bottom of the heat dissipation boss and the inner surface of the bottom of the chamber. The inner surface of the bottom of the chamber is provided with a plurality of supporting bosses. One outer edge of the control circuit board inserts into the gap, which enables the outer side surface of the control chip to cling to the inner side surface of the heat dissipation boss. The control circuit board is supported by upper surfaces of the supporting bosses.
