Embodiment 1
[0028] Embodiment 1: see figure 2 Describe this embodiment, the permanent magnet reluctance linear motor of this embodiment includes a primary, a secondary and an air gap, the primary includes a primary iron core, a primary armature winding and a permanent magnet, and the secondary includes a secondary iron core;
[0029] On the air gap side of the secondary core, there are teeth and slots in the transverse direction, and the teeth and slots are arranged alternately along the moving direction; on the side of the primary iron core facing the air gap, there are slots in the transverse direction, forming 24 teeth, and the phase number of the motor is Three-phase; the primary armature winding is a three-phase winding. Along the direction of movement, two adjacent teeth are used as a group, and the 24 teeth are divided into 12 groups. The 24th and 23rd teeth of the primary core are wound on the 24th and 23rd teeth. One coil, one coil is wound on the 22nd and 21st teeth, and so on,...
