Abstract

The invention provides a permanent magnet linear oscillation motor, which includes a mover part and a stator part; the mover part includes a shaft and a mover iron core, and the mover iron core is installed and fixed on the shaft; the stator part includes a primary iron core, a permanent magnet, Coil bobbin, first coil and second coil, the primary iron core is provided with a groove for accommodating the permanent magnet, coil bobbin, first coil and second coil, the first coil and the second coil are symmetrical with respect to the permanent magnet. It is arranged on the coil bobbin, and when the first coil and the second coil are energized, a magnetic field is generated, thereby driving the mover part to reciprocate along the axis direction of the shaft. The invention also relates to an electric device. In the permanent magnet linear oscillation motor and electric equipment of the present invention, the mover part is lighter in weight, has fast dynamic response, the permanent magnet is not easy to lose magnetism, and the motor operation is more reliable.

Description

technical field

[0001] The invention relates to the field of oscillating motors, in particular to a permanent magnet linear oscillating motor and electric equipment. Background technique

[0002] Traditional technology usually uses transmission mechanisms such as ball screws, gears, and cranks to convert the rotary motion of the rotary motor into reciprocating linear motion, which has low transmission efficiency, low mechanical reliability, and difficult maintenance. The linear motor is used to directly drive the load for reciprocating motion, which reduces friction loss, reduces the mechanical time constant of the system, and improves the efficiency and reliability of the system. The linear oscillating motor uses electromagnetic force to generate reciprocating linear motion, and is generally used in electric toothbrushes, air compressors, shavers, camera electromagnetic shutters, speakers, electric hammer machines, mixers, refrigerators, sewing machines, packaging and bindi...
