Title:
RECIPROCAL ROTATION ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2021/097705
Kind Code:
A1
Abstract:
The present invention relates to a reciprocal rotation electric motor. The electric motor comprises an electric motor shell, a stator assembly, a rotor assembly, an end cover and a limiting assembly, wherein the limiting assembly contains a first magnet arranged at a first position, a second magnet arranged at a second position, and a movable magnet capable of swinging in a swinging area between the first magnet and the second magnet along with the rotation of the rotor assembly; the movable magnet is opposite magnetic poles, in the same direction, of the first magnet and the second magnet; magnetic force among the rotor assembly, the movable magnet, the first magnet and the second magnet enables a rotating shaft of the rotor assembly to reset to a middle position of reciprocating rotation when the electric motor is disconnected from a power supply; and when a starting current is input into the electric motor, magnetic force among a rotating magnet, the movable magnet, the first magnet, the second magnet and the stator assembly enables the rotating shaft to be maintained at the middle position of reciprocating rotation. The electric motor is short in terms of reversing time, has a long service life and is capable of accurately rotating in a reciprocating manner.
