Abstract
The utility model discloses a permanent magnet linear synchronous motor, comprising a primary iron core and a secondary iron core. The primary iron core may further comprise an iron core with a main tooth, an iron core with additional teeth, and a polyphase winding. The secondary iron core may further comprise a magnetic conduction yoke, and a permanent magnet topology. According to the permanent magnet linear synchronous motor and inhibition method for tooth socket thrust thereof, the thrust ripple generated by an iron groove is reduced without using chute or oblique magnetization; and the motor secondary adopts a special-shaped magnetic steel disclosed in the utility model, thus making the distribution of the tooth socket thrust more uniform. The servo performance of the permanent magnet linear synchronous motor is improved, and the dynamic characteristic, and location precision of a motion system are also improved.
Description
Technical field
The utility model relates to the inhibition method of a kind of motor and thrust thereof, relates in particular to the inhibition method of a kind of permanent magnetic linear synchronous motor and teeth groove thrust thereof.
Background technology
It is secondary that the high thrust permanent magnetic linear synchronous motor adopts the high-performance rare-earth magnet steel to do more, and the spline silicon steel sheet core is done elementary, to improve exerting oneself of unit volume motor, i.e. pushing force density.Just because of the existence of teeth groove, cause motor gas-gap inhomogeneous, cause force oscillation, i.e. teeth groove power.This thrust also causes the noise of high-speed motion system easily except that the low-speed performance of motion-affecting flatness and precise motion system.
In the prior art, in order to reduce teeth groove power, generally adopt the method for skewed slot or oblique magnetic, select different skewed slots or oblique magnetic degree, can reduce teeth groove thrust, but also can weaken effective push simultaneously, and slot effect is more little, the amplitude that effective push is cut down is big more; Secondly, skewed slot or oblique magnetic can increase the difficulty and the manufacturing cost of manufacturing process.
The utility model content
Technical problem to be solved in the utility model is to be a kind of permanent magnetic linear synchronous motor need be provided, and the inhibition method of teeth groove thrust, with reduce or overcome because of skewed slot or tiltedly magnetic to the influence of effective push.
In order to solve the problems of the technologies described above, the utility model provides a kind of permanent magnetic linear synchronous motor, comprising: elementary iron core and secondary iron core.
Described elementary iron core may further include: with the iron core of main tooth.
Described elementary iron core can further include: the iron core of band additional teeth.
Described elementary iron core also may further include: polyphase windings.
Described secondary iron core may further include the magnetic conduction yoke.

The permanent magnetism topology is bonded on the described magnetic conduction yoke.
The magnet of described permanent magnetism topology can be diamond structure.
The magnet of described permanent magnetism topology also can be width ratio and the optional diamond structure in inclination angle.
Can be provided with groove on the described elementary iron core, be used to embed winding.
The utility model permanent magnetic linear synchronous motor, and the inhibition method of teeth groove thrust under the situation that does not adopt skewed slot or oblique magnetic, reduce because the force oscillation that the iron core fluting produces; The special-shaped magnet steel that motor secondary adopts the utility model to disclose can make being more evenly distributed of teeth groove thrust.The utility model helps to improve the servo performance of permanent magnetic linear synchronous motor, and the dynamic characteristic of kinematic system and positioning accuracy.
