Abstract

The invention discloses a double-primary coplanar multiphase linear permanent magnet synchronous motor, belonging to the technical field of motors. The invention aims to solve the problems of large secondary structure deformation, poor rotor stability, low thrust density and poor dynamic response when an existing double-side secondary coreless structure linear permanent magnet synchronous motor outputs large thrust. The double-primary coplanar multiphase linear permanent magnet synchronous motor comprises two primary units, a secondary unit, a rotor supporting mechanism and an engine base, wherein each primary unit comprises a primary winding and a primary substrate on which the primary winding is arranged; the secondary unit comprises an upper secondary unit, a lower secondary unit and a middle supporting plate; the two primary windings are arranged on the left side and the right side of the primary substrate respectively and are correspondingly connected in series, and phase differences exist between the corresponding phase windings in a movement direction; and the secondary unit is of a bilateral structure and arranged on the two sides of the primary units, and two air gaps are formed between the primary units and the secondary unit. The invention is applicable to the linear permanent magnet synchronous motor.

Description

technical field [0001] The invention relates to a double-primary coplanar multi-phase linear permanent magnet synchronous motor, which belongs to the technical field of motors. Background technique [0002] Figure 1-Figure 3 It is a structural schematic diagram of a traditional double-sided secondary ironless structure linear permanent magnet synchronous motor. The secondary of the motor is composed of a yoke plate and a flat permanent magnet. Arranged in sequence and fixed on the air gap side of the secondary yoke plate, the magnetization directions of the corresponding permanent magnets on the left and right sides of the bilateral secondary 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 primary winding interacts with the magnetic field of the secondary permanent magnet to generate electromagnetic force and pus...
