A CONTROL MODULE FOR AN ELECTRIC MOTOR OR GENERATOR

摘要

A control module for an electric motor having a stator that includes a first surface, wherein cooling fluid is arranged to flow within the stator for providing cooling to the first surface, the power module comprising a power device having switching elements for controlling current flow in coil windings mounted on the stator; a control device for controlling the operation of the switching devices; a housing with a first side for mounting to the first surface of the stator, wherein the first side of the housing includes an aperture for allowing a portion of the power device to be in contract with the first surface of the stator when the housing is mounted to the first surface for providing cooling to the switching elements, wherein the control device is arranged to be mounted in the housing on an opposite side of the power device to the first side of the housing and an elastomer is located over the power device and the control device for providing an electrical insulation barrier over the switches on the power device and electrical components on the control device.
