摘要： This application describes a motor that includes a housing, an output shaft, a conductive bearing, and a conductive component. The output shaft is disposed in the housing. A positioning hole is disposed on an end face of a first end of the output shaft, and the positioning hole is disposed coaxially with the output shaft. The conductive bearing is disposed in the positioning hole, and includes an inner ring, and an outer ring that is fixedly connected to the output shaft. One end of the conductive component is fixedly connected to the inner ring of the conductive bearing, and the other end is connected to the housing. In this application, the motor can output, by using the conductive bearing and the conductive component, charges accumulated in the output shaft, to eliminate a generated common-mode voltage.

摘要： An electric motor with multiple electric gears to achieve an effect equivalent to mechanical gears in transmissions, enabling more efficient use of electricity at a wider range of speeds and torques is described. The Gears for Electric Motor (GEM) comprises a multi-phase motor having a concentric set of dedicated rotors to specific ranges of revolutions per minute (RPMs), and corresponding stators. The rotors and stators may be fitted within each other or positioned approximately parallel to each other along the longitudinal axis of the motor shaft. A controller determines which rotors are activated based on desired efficiency, torque and speed. Alternately, or in addition, magnets and coil pairs are constructed with varying properties to make more efficient use of electricity at a wider range of speeds and torques.

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.
