Embodiment Construction
[0030] The following is a detailed description of the double redundant permanent magnet synchronous motor with double Y phase shift of 30° and no electromagnetic coupling between the windings of each phase of the present invention in combination with the embodiments and accompanying drawings.
[0031] In the present invention, there is no electromagnetic coupling between the phase windings of the double Y phase shift of 30°, and the double redundant permanent magnet synchronous motor is mainly through the selection of the number Z of large teeth on the stator of the six-phase permanent magnet synchronous motor. 0 (Multi-turn coils are wound on each large tooth) and the number of pole pairs of the permanent magnet rotor p 0 Coordination between, the number of motor phases is 6, Z 0 is an even number, p 0 is an odd number, Z 0 with p 0 There is no common divisor between them, and there exists Z 0 = 2p 0 The relationship of ±2; and there are 12 small teeth arranged on the st...
