Abstract
An inner rotor type molded motor controlled by pulse width modulation using an inverter circuit includes a pair of electrically conductive brackets attached to a load-side portion and an anti-load-side portion of a motor frame. An electrically conductive tape is attached on the outside of the motor frame to extend between the brackets, thereby short-circuiting the brackets to each other. In this manner, electrical erosion in the molded motor can be prevented.
