Embodiment Construction

[0060] In order to make it easy to understand the technical means, creation features, achieved goals and effects of the present invention, the present invention will be further described below with reference to the specific figures.

[0061] The modeling method of double-phase permanent magnet synchronous motor is characterized in that it includes three parts:

[0062] Step 1. Equivalent transformation from dual three-phase windings to three-phase windings

[0063] (1) Make assumptions and simplify data

[0064] 1) Two sets of stator windings A 1 B 1 C 1 and A 2 B 2 C 2 The space is staggered by 30° electrical angle, and each set of three-phase windings is symmetrical in space, that is, the number of turns of each phase winding is the same, and the phase winding interval is 120° spatial electrical angle.

[0065] 2) The normal operation of the motor is as follows: the three-phase symmetrical windings are fed with three-phase symmetrical currents, and the time difference...

Abstract

The invention relates to a method for modeling motors, in particular to a method for modeling double three-phase permanent-magnetic synchronous motors. The method first reasonably assumes the running states and related parameters of the double three-phase permanent-magnetic synchronous motors, thereby achieving the aims of few modeling parameters, easy determination and simple modeling process. Inaddition, the method transforms a double three-phase winding equivalently into a three-phase winding through simple steps, thereby realizing the aim of using a mature three-phase winding modeling method to solve an immature double three-phase winding modeling method and also achieving the aims of few modeling parameters, easy determination and simple modeling process.

Description

technical field [0001] The invention relates to a modeling method of an electric motor, in particular to a modeling method of a dual-phase three-phase permanent magnet synchronous motor. Background technique [0002] The dual-phase motor system has obvious advantages over the performance of the three-phase motor system: low-voltage standard power devices can be used to achieve high-voltage and high-power processing capability; the number of space harmonics with greater influence increases, the amplitude decreases, and the torque ripple decreases. ; The magnetomotive force waveform is improved; the motor efficiency is improved; the motor noise is reduced; the multi-phase redundant structure of the speed control system improves the reliability at the system level. [0003] There have been many studies on mathematical models and simulations of dual three-phase permanent magnet synchronous motors. Some combine the multi-loop theory of AC motor with the finite element method of ...
