Abstract

The invention discloses a thrust fluctuation compensating secondary of an annular winding permanent magnet linear synchronous motor, which is composed of a plurality of plate-shaped secondary assemblies and forms a multi-faceted air gap structure with a primary armature with annular winding; the primary The cross section of the armature is rectangular, and the permanent magnet in the secondary assembly corresponding to its length interacts with the primary armature current to generate electromagnetic thrust. shift to achieve compensation for the electromagnetic thrust fluctuation component. The present invention can realize more stable electromagnetic thrust output while ensuring the improvement of thrust density and structural compactness.

Description

technical field [0001] The invention relates to the field of motors, in particular to a thrust fluctuation compensation type secondary of an annular winding permanent magnet linear synchronous motor. Background technique [0002] Permanent magnet linear synchronous motors have the advantages of high thrust density, fast dynamic response, and high positioning accuracy, and have broad application prospects in CNC machine tools, cordless elevators, and automated production lines. The toroidal winding is a toroidal coil wound on the primary iron core. The plane of the coil is perpendicular to the direction of movement of the motor. It has the advantages of non-crossing ends, small footprint and good mechanical strength. It has been widely concerned and applied in permanent magnet linear synchronous motors. However, the primary armature winding current and magnetic potential harmonics of the toroidal winding permanent magnet linear synchronous motor are relatively large, and larg...
