Abstract

The invention discloses a brushless alternating current reciprocating rotation motor which comprises a stator assembly, a rotor assembly and a reciprocating driving assembly. the stator assembly comprises a stator magnet, the rotor assembly comprises a motor shaft and a rotor lamination arranged on the motor shaft, lamination poles corresponding to the stator magnet are arranged on the rotor lamination, the reciprocating driving assembly comprises a driving lamination, a coil and a driving magnet, and two ports at an opening of the driving lamination are arranged towards the driving magnet; when alternating current is supplied to the coil, with the change of the current direction of the coil, the two ports at the opening of the driving lamination generate continuously-changing polarities,the driving magnet can drive the rotor assembly to swing back and forth, and therefore the motor shaft is driven to rotate around the axis in a reciprocating mode. After the rotor assembly rotates bya certain angle around the axis, the stator magnet applies magnetic force to drive the rotor lamination to reset to the original position, so that inertia is increased, and amplitude attenuation caused by damping is reduced, a brand-new motor structure is adopted, reliability is high, and the service life is long.

Description

technical field [0001] The invention relates to the field of motors, in particular to a brushless AC reciprocating motor. Background technique [0002] The AC reciprocating motor is a motor in which the motor shaft reciprocates at a certain angle around the axis after the AC power is applied. This kind of micro motor is widely used in electric toothbrushes, massage sticks, grinders and other fields. At present, such motors generally have the problems of poor structural reliability and short life. Contents of the invention [0003] The purpose of the present invention is to solve at least one of the technical problems in the prior art, and provide a brushless AC reciprocating motor, which adopts a brand new motor structure, has high reliability and long service life. [0004] According to the first aspect of the present invention, there is provided a brushless AC reciprocating motor, comprising: [0005] The stator assembly includes a casing, a first magnet bracket and a...
