Motor and ventricular assist device

Abstract

The invention relates to a motor and a ventricular assist device. The motor comprises a shell, a sensing assembly, a stator assembly and a control assembly. The shell defines a containing cavity. The sensing assembly comprises a sensing circuit board, and the sensing circuit board is accommodated in the accommodating cavity; the stator assembly penetrates through the sensing circuit board; the control assembly comprises a control circuit board electrically connected with the sensing circuit board, the control circuit board is contained in the containing cavity, and the control circuit board is arranged on the peripheral side of the stator assembly, so that the control circuit board does not occupy the space of the motor in the axial direction, the thickness of the motor is reduced, and the service life of the motor is prolonged. The risk that the ventricular assist device is in contact with other organs in the thoracic cavity when being implanted into the body of a patient is reduced, so that the safety performance of the ventricular assist device is improved.
