Description

39-slot 12-pole three-phase permanent magnet synchronous motor winding embedding method for six-layer sleeve wave winding

technical field

The invention belongs to the field of electrical engineering and relates to a winding and embedding method for a six-layer sleeve wave winding suitable for a 39-slot, 12-pole three-phase permanent magnet synchronous motor.

Background technique

In some special applications, extremely high requirements are placed on the volume and weight of permanent magnet synchronous motors. Under such high requirements, the number of motor pole pairs needs to be selected more during motor design to reduce the thickness of the iron core of the stator and rotor yoke; at the same time, the axial length of the end of the stator winding should be designed as short as possible.

At present, the shortest axial length of the stator winding end of the permanent magnet synchronous motor is the fractional slot concentrated winding. Although the axial length of the end of the fractional slot concentrated winding is short, the harmonic component of the magnetomotive force of the fractional slot concentrated winding armature reaction is not only rich, but also has a high amplitude; if the permanent magnet rotor is a surface mount structure, and the motor speed is relatively high When it is high, high eddy current and hysteresis loss will be generated on the permanent magnet, resulting in low efficiency of the motor, and even demagnetization of the permanent magnet will occur in severe cases.

If fractional slot concentrated winding is not used, double-layer short-pitch distributed winding can be used. For the double-layer short-pitch distributed winding with a large number of poles, most of the coils are multi-turn, and the double-layer short-pitch distributed stacked winding is usually used. However, the axial length of the winding end of the simple double-layer short-pitch distributed stacked winding is relatively long; at the same time, there are many connecting lines between the coils under different magnetic poles; It will cause the winding end on the side of the motor winding lead-out line to be thicker or the axial length will be longer. When it is also considered that the permanent magnet electromotive force waveform of the permanent magnet synchronous motor is as close as possible to a sine wave, the number of pole pairs of the motor is selected more, and the number of stator slots is less, the number of slots occupied by each pole and each phase is a fractional slot; The 39-slot 12-pole three-phase permanent magnet synchronous motor is one of the slot-pole matching forms that can meet the above requirements. The connection wires between the wave winding coils are relatively short. For a 39-slot 12-pole three-phase permanent magnet synchronous motor, if the three-phase winding is separated according to the traditional 60° phase-band phase separation method, and the traditional double-layer short-distance When the distributed wave winding is embedded, the winding symmetry obtained is poor, and the axial length of the winding end is relatively long. It is necessary to adopt a new phase separation method and a new embedded wire process to ensure that the axial length of the stator winding end is relatively small. short, and the requirement that the three-phase winding be as symmetrical as possible.
