    摘要： An electric pump. The electric pump comprises a PCB board, wherein the PCB board is formed with a power source input port. The electric pump further comprises a common-mode filter, wherein the common-mode filter comprises a common-mode inductor, and the common-mode inductor is arranged close to the power source input port; and in a direction perpendicular to a plane on which the PCB board is located, a wiring is not provided at the common-mode inductor corresponding to a wiring film layer in the PCB board. By means of the technical solution of the present invention, a common-mode signal in a power source signal transmitted by means of a power source input port is effectively filtered, thereby enhancing the electromagnetic compatibility of a PCB board, and enhancing the electromagnetic compatibility of an electric pump.

    摘要： Provided is a motor apparatus in which no increase in its motor diameter while securing redundancy of motor power control. A motor apparatus (10) includes an electric motor (20) having a rotation shaft (23), a first control circuit board (41), onto which a first power circuit (41a) and a first control circuit (41b) are mounted, and a second control circuit board (42), onto which a second power circuit (42a) and a second control circuit (42b) are mounted. The two control circuit boards (41, 42) are arranged with an overlapping region when viewed along the axial direction (stippled line m) of the rotation shaft (23). The extension line (m) of the rotation shaft (23) of the motor (20) intersects the overlapping region.

    摘要： The present disclosure discloses an integrated electrical motor, comprising at least two sets of corresponding stators and rotors, wherein the at least two sets of corresponding stators and rotors are mounted within the same housing, and are connected to the corresponding controllers, and the rotors are mounted on the same shaft. The total output torque of the electrical motor can be distributed to the shaft from different stator/rotor pairs, and when one or more of the sets of stators and rotors have malfunction, the remaining stators and rotors maintain running. The integrated electrical motor of the present disclosure has compact structure, small axial dimension, distributable torque, high safety margin and high reliability.
