Problems solved by technology

[0002] It is pointed out in the related technology that the structure of the motor is very compact, and after the magnetic ring is assembled on the end ring, the phenomenon that the magnetic field of the motor itself and the magnetic field of the magnetic ring will be superimposed will cause the Hall output signal to be unstable, and an abnormal signal will appear when the motor is locked.

Abstract

The invention discloses an induction machine. The induction machine comprises a stator, a rotor, a printed circuit board and a shielding element; the rotor is rotatably arranged in the stator and a magnetic ring is arranged on the rotor; the printed circuit board is arranged on the stator and located at one end, adjacent to the magnetic ring, of the stator, and a hall device is arranged on the printed circuit board; the shielding element is arranged on the printed circuit board to shield leakage flux of the stator and the leakage flux of the rotor so that the hall device is only capable of sensing the magnetic field of the magnetic ring. According to the induction machine, the shielding element is arranged on the printed circuit board to effectively avoid the superposition of the magnetic field of the induction motor and the magnetic field of the magnetic ring, and therefore, the stability of the magnetic field of the magnetic ring is guaranteed, and furthermore, the stability of hall output signals is ensured.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to an induction motor. Background technique [0002] It is pointed out in related technologies that the structure of the motor is very compact, and after the magnetic ring is assembled on the end ring, the magnetic field of the motor itself and the magnetic field of the magnetic ring will superimpose, resulting in unstable Hall output signals and abnormal signals when the motor is locked. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to propose an induction motor which can ensure the stability of the magnetic ring magnetic field. [0004] The induction motor according to the embodiment of the present invention includes: a stator; a rotor, the rotor is rotatably arranged in the stator, and a magnetic ring is arranged on the rotor; ...
