ABSTRACT:
A power module for a motor in which the module is arranged to house both the high power devices needed to drive the phase windings of the motor and the control electronics needed to control the operation of the high power devices. The components are arranged such that the thermal energy generated by the high power devices is directed away from the control electronics for subsequent dissipation. An insulated metal substrate is used as the base of the module for directing the thermal energy. Further, the module components can be easily assembled through the use of solderless resilient connections from the control electronics to the other components in the module. The module employs a base, a power shell coupled to the base, and a circuit board positioned within the internal chamber of the power shell. The power shell has a plurality of walls forming an internal chamber and at least one conductive region. At least one electronic device is mounted to the conductive region.
