Problems solved by technology

The disadvantage of the above structure is that the permanent magnet is attached to the outer surface of the mover iron core. When the motor is working, the coil magnetic field will have magnetization and demagnetization effects on the permanent magnet, which makes the reciprocating motion of the motor not stable and reliable, and the mover has a large mass.
[0004] Chinese patent ZL201020164959.6 discloses a moving iron linear oscillating motor. Permanent magnets are installed between the stator yoke and the stator core, and 4 stator cores are evenly distributed on the inner circumference of the stator yoke. There are 2 coils, the structure is more complicated
This structure is more complex and the thrust density is lower

Abstract

The invention provides a permanent magnet linear oscillating 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 fixed on the shaft; the stator part includes a primary iron core, a permanent magnet, The coil frame, the first coil and the second coil, the primary iron core is provided with grooves for accommodating the permanent magnet, the coil frame, the first coil and the second coil, and the first coil and the second coil are symmetrical to the permanent magnet It is arranged on the coil frame, 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 axial direction of the shaft. The invention also relates to an electric device. In the permanent magnet linear oscillating motor and electric equipment of the present invention, the mover part has lighter weight, quick dynamic response, the permanent magnet is not easily demagnetized, and the motor runs more reliably.

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...
