Abstract

The invention discloses a composite winding ironless linear permanent magnet synchronous motor and relates to a coreless linear permanent magnet synchronous motor, and solves a problem that when applied in the field of ultra-precision motion control, a linear secondary permanent magnet synchronous motor with double secondary coreless structure has large thrust fluctuation, low power density and large secondary eddy current loss. The composite winding ironless linear permanent magnet synchronous motor comprises a primary side and a secondary side. The primary side comprises a primary substrateand two primary windings. The two primary windings are arranged on the left and right sides of the primary substrate respectively. The windings in corresponding phases of the two primary windings areconnected in series. In the direction of motion, the windings in the corresponding phases of the two primary windings have a phase difference. The secondary side is a U-shaped bilateral structure andis arranged on both sides of the primary side. Two air gaps are arranged between the primary and secondary sides. The composite winding ironless linear permanent magnet synchronous motor is mainly applied to the field of ultra-precision motion control.

Description

technical field [0001] The invention relates to a coreless linear permanent magnet synchronous motor, which belongs to the field of motors. Background technique [0002] The structure of the traditional bilateral secondary ironless structure linear permanent magnet synchronous motor, see for details Figure 26 with 27 As shown, the secondary of the motor is composed of a yoke plate and a flat permanent magnet. The permanent magnets are magnetized in parallel in the transverse direction. The permanent magnets are arranged and fixed on the air gap side of the secondary yoke plate in sequence along the N and S phases along the moving direction. Both sides of the secondary The magnetization directions of the corresponding permanent magnets on the left and right sides are the same, and the primary is located between the two secondary. The normal component of the magnetic force line generated by the permanent magnet passes through the primary vertically, and the current of the pr...
