A motor assembly for driving a pump or rotating device having a power plane with a multi-layer power and control printed circuit board assembly

摘要

A motor assembly for driving a pump or a rotating device is characterized by a power plane having a circular geometry mounted within a space envelope which is formed on the end plate between an inner hub portion and a peripheral portion Has a similar circular geometry and the peripheral portion extends circumferentially around the space envelope of the end plate. The power plane includes a power layer having a high temperature power module for providing power to the motor, a control layer having a low temperature control electronics module for controlling power provided to the motor, and a control module Layer circuit board or assembly having a thermal barrier between the power layer and the control layer and a printed circuit board layer that provides an electrical connection path between the electronics modules and also provides insulation between the power layer and the control layer.
