Embodiment Construction

[0037] 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.

[0038] In order to solve the defects existing in the modeling of the double-three-phase motor system in the prior art, the present invention proposes a new mathematical modeling method for the double-three-phase permanent magnet synchronous motor.

[0039] This method is based on the principle of generating the same magnetomotive force and constant power. First, the dual three-phase windings are equivalently transformed into dual two-phase windings, and then the dual two-phase windings are equivalently transformed into two-phase windings. After two winding transformations, the dual three-phase winding is equivalently transformed into a two-phase quadrature winding. Apply the mature mathematical model in the two-phase rotating coordinate system t...

Abstract

The invention discloses a method for modeling a double three-phase permasyn motor based on winding complex transformation. The method is to equivalently transform a double three-phase winding into a double two-phase winding, and equivalently transform the double two-phase winding into a two-phase winding based on the principle of same magnetomotive force generation and invariable power. After twice winding transformations, the double three-phase winding is equivalently transformed into a two-phase orthogonal winding. By application of a mature mathematical model under a two-phase rotary coordinate system, mathematical modeling of the double three-phase permasyn motor under a d-q coordinate system and simulation modeling based on Matlab / Simulink can be completed. The method is relative simple, and has clear physical concept. The simulation result is compared with corresponding test data, and the maximum error between the two is within 5 percent.
