ABSTRACT:
An integral brushless DC motor and drive package is disclosed that includes the brushless DC motor and drive circuitry supported by one of the motor end caps. The drive circuitry includes power electronic devices for converting input power to pulsed power for the motor. The power switching components extend from a circuit board and are received within recesses of the end cap. The switching components are electrically insulated from the end cap, but are thermally conductive to the end cap within the recesses to dissipate heat during operation. The switching components are preferably disposed in radially equally spaced positions on the circuit board to provide even heat loading to the end cap.
