Embodiment Construction
[0062] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0063] The modeling method of double three-phase permanent magnet synchronous motor is characterized in that it includes three parts:
[0064] Step 1. Equivalent transformation from double three-phase winding to three-phase winding
[0065] (1) Make assumptions and simplify the data
[0066] 1) Two sets of stator windings A 1 B 1 C 1 and A 2 B 2 C 2 Staggered by 30° electrical angle in space, each set of three-phase windings is symmetrical in space, that is, the number of turns of each phase winding has the same wire gauge, and the phase windings are separated by 120° spatial electrical angle.
[0067] 2) The normal operation of the motor is as follows: three-phase symmetrical windings are fed with three-phase symmetrical currents, and th...
