Problems solved by technology

[0029] However, as mentioned above, although the motor can rotate forward or backward at high speed, it cannot do high-speed reciprocating rotation in a certain area
In this way, it cannot be applied to machinery or equipment that requires high-speed reciprocating rotation
In addition, if it is adopted, a conversion mechanism for converting rotary motion into linear motion must be additionally installed, which leads to a problem of cost increase

Abstract

A vibration motor includes: a first tooth having recesses and protrusions on its front surface; a stator having first teeth formed in pairs on the surface of its inner circumference; a rotor having a front surface of its second teeth having recesses and protrusions, and engages the recesses and protrusions on the first tooth of the stator. The motor can rotate reciprocally in the rotating area without any conversion device to convert it into linear motion. Plus, it can be easily connected to existing equipment.

Description

technical field [0001] The present invention relates to a vibration motor, and more particularly to a vibration motor whose concavities and convexities are arranged on the inner circumferential surfaces of a rotor and a stator to increase the contact area, thereby increasing the torque of the motor, and controlling the AC power applied to the motor , to variably control the area where the rotor reciprocates, thereby increasing the efficiency of the compressor. Background technique [0002] Generally, an electric motor controls the operation of a switching device to turn on or off power to a coil wound on a polyphase stator to generate a rotational torque. Because the excitation state of the rotor and stator of the motor changes continuously, a forward rotational moment is formed through the generated magnetic attraction force. If the excitation state between the rotor and the stator of the motor does not change, the rotor will stop at a specific Location. [0003] In addit...
