[0036] Specific implementation method
[0037] The principle of adding a compensation block to cancel the magnetic resistance of the present invention can be used in various types of permanent magnet synchronous linear motors. The present invention will be described in detail below.
[0038] figure 1 Among them, the permanent magnet synchronous linear motor is composed of a primary iron core 4, a coil winding 3, a permanent magnet 2, a secondary iron core 1, wherein the primary iron core 4 and the secondary iron core 1 are the non-linear ferromagnetic materials Steel_1008 commonly used in motors; The coil winding 3 is an enameled wire; the material of the permanent magnet 2 is NdFe30. The permanent magnet synchronous linear motor has a 9-tooth 10-pole structure (that is, the primary iron core 4 has 9 teeth, corresponding to 10 permanent magnets 2 on the secondary iron core 1), the coil winding 3 is a concentrated full-pitch winding, and the three-phase windings are distribut...
