Embodiment Construction
[0035] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0036] In order to explain the structural features and beneficial effects of the semi-closed slot fault-tolerant permanent magnet cylindrical linear motor of the present invention more simply and clearly, a detailed description will be given below in conjunction with a specific five-phase fault-tolerant permanent magnet cylindrical linear motor.
[0037] In order to illustrate the present invention more clearly, the pole-slot ratio of the semi-closed slot-type fault-tolerant permanent magnet cylindrical linear motor of the present invention is embodied, and m=5 is selected, which is a five-phase motor, and the corresponding number of slots and poles of the motor N respectively s =2*m*2=20,N p =18. And the cylindrical linear motor of this embodiment adopts the concentrated winding phase-splitting mode.
