摘要： A motor assembly for driving a pump or rotary device features a power plane with a circular geometry to be mounted inside a space envelope having a similar circular geometry formed on an end-plate between an inner hub portion and a peripheral portion that extends circumferentially around the space envelope of the end-plate. The power plane is a multi-layer circuit board or assembly having: a power layer with higher temperature power modules for providing power to a motor, a control layer with lower temperature control electronics modules for controlling the power provided to the motor, and a thermal barrier and printed circuit board layer between the power layer and the control layer that provides electrical connection paths between the power modules of the power plane and the control electronics modules of the control layer, and also provides insulation between the power layer and the control layer.

摘要： A motor assembly for driving a pump (e.g., liquid pump) includes an electric motor with an output shaft. A motor frame houses the electric motor so that the output shaft protrudes from an end of the motor frame. A plate assembly is coupleable about the output shaft to the end of the motor frame. The please assembly has a cavity that houses motor drive electronics. The plate assembly further defines a duct that extends between a central opening and one or more openings on an outer radial wall of the plate assembly. A fan is coupled to the output shaft so that the plate assembly is disposed between the fan and the motor frame. Rotation of the output shaft by the electric motor rotates the fan, causing air to flow through the duct. Air flow through the duct inhibits heat transfer between the electric motor and the motor drive electronics.
