Abstract

Previous motor control power electronics were mounted on heat sink by clips and provided with only limited air cooling for heat dissipation. The electronics and retaining clips were positioned adjacent to the rotor of the motor. This previous assembly design of the heat sink and retaining clips disrupted the air flow, required ex- cessive space and was difficult and costly to implement.
