Abstract
The invention discloses a thrust fluctuation active compensation type linear permanent magnet synchronous motor and belongs to the technical field of motors. By the thrust fluctuation active compensation type linear permanent magnet synchronous motor, the problems that the thrust fluctuation of a linear motor can be only restrained to a certain extent and an effective thrust of the motor can be reduced by using the conventional method for reducing the thrust fluctuation of the linear motor are solved. An air gap is formed between a primary and a secondary; the primary comprises an armature core and an armature winding; and the armature winding of the primary has a surface mounted structure or the primary has a tooth groove structure. The thrust fluctuation generated by a thrust fluctuation compensation unit arranged at the end of the armature core is counteracted with the thrust fluctuation generated by the linear permanent magnet synchronous motor by controlling current of a compensation winding through a compensation controller or by serially connecting the compensation winding and the armature winding; therefore, an aim of actively eliminating or reducing the thrust fluctuation of the linear motor can be fulfilled. The invention is applicable to linear permanent magnet synchronous motors.
Description

For permanent-magnetism linear motor,, be called end detent force F because the existence of elementary longitudinal end unshakable in one's determination and stator permanent magnet even under the cold situation of motor windings, also exists tangible longitudinal end efficacy
End, it is the main component that causes the thrust performance fluctuation, and is as shown in Figure 8, has tangible end effect in elementary two ends unshakable in one's determination.End detent force F
EndRelevant with many factors such as elementary physical dimension unshakable in one's determination and winding construction, motor pole span, permanent magnet pole are wide, be the periodic function of pole span, its amplitude depends primarily on the ratio of pole span and effective air gap, and is irrelevant with the linear motor driving electric current.For the end detent force F that causes force oscillation
End, can make that getting into winding magnetic flux unshakable in one's determination through air gap keeps consistency preferably, thereby make end detent force F through changing the length and the end shape of elementary iron core
EndReduce.

Slot, and cause force oscillation.F
SlotClosely related with tooth pitch, be the periodic function of tooth pitch, irrelevant with the linear motor driving electric current.For the teeth groove detent force F that causes force oscillation
Slot, can it be reduced through methods such as the cooperation of choose reasonable utmost point groove, elementary skewed slot, the oblique utmost point of secondary permanent magnet, optimization permanent magnet width and slot forms in theory.
