Abstract: A control module for a high power motor includes a mounting frame made up of thermally-conductive material including a bottom wall and four side walls; a circuit board disposed within the side walls of the mounting frame; power switches configured as an inverter circuit oriented in two arrays mounted on opposite surfaces of the circuit board; an auxiliary circuit board extending substantially perpendicularly from the circuit board; capacitors mounted on the auxiliary circuit board with a long axis thereof extending parallel to the circuit board and away from the power switches; and connectors mounted between an edge of the circuit board and distal ends of the capacitors.

Abstract: A control module for a high-power electric motor may include a metal base, an insulating wall fastened to the metal base, and a circuit board disposed within the insulating wall. The circuit board may include a first surface that faces the metal base and a second surface opposite the first surface. A plurality of power switches may be mounted on the first surface of the circuit board and configured as an inverter circuit. A thermally conductive electrically insulating layer may be between the circuit board and the metal base. Power output terminals may be mounted on the second surface of the circuit board. An insulating frame may extend between at least one pair of the power output terminals. One or more fasteners may be received through the insulating frame, the circuit board, and the thermally conductive electrically insulating layer and fastened to the metal base.
