Description

Technical Field

[0001] The utility model belongs to the technical field of micro motors, in particular to a reciprocating high-frequency motion micro motor. Background Art

[0002] The working principle of reciprocating high-frequency micro motors is to use electromagnetic fields to generate torque to rotate the motor. Specifically, the motor consists of a stator and a rotor. When current passes through the winding on the stator, a rotating magnetic field is generated, which drives the rotor to rotate. By changing the current and phase of the winding, the speed and torque of the motor can be controlled.

[0003] A reciprocating high-frequency micro motor will generate a lot of heat when working. If the heat is not dissipated in time, the motor may be damaged due to overheating. Heat dissipation holes are set on the motor to dissipate heat, so that a lot of dust will accumulate inside the motor when it is not working. Dust entering the motor can easily affect the operation of the motor and shorten its service life. Summary of the invention

[0004] The utility model aims to provide a reciprocating high-frequency motion micro motor, which can connect the interior with the external environment to dissipate heat when working, thus avoiding the risk of overheating; and can isolate the interior from the external environment when not working, thus preventing dust in the external environment from entering the interior, thereby extending the service life.
