Abstract

The invention discloses a stator iron core with all phases of salient poles in concentrated arrangement and a motor with all phases of salient poles in concentrated arrangement, which belongs to the motor field. The salient poles of the stator iron core are arranged in q-phase n groups. Each group has z salient poles in each phase, and z salient poles are in adjacent concentrated arrangement. q, n and z are natural numbers. q is equal to or greater than 2. z is equal to or greater than 2. The salient poles are arranged in the circumferential direction of the stator iron core in the order of the first group of salient poles, the second group of salient poles, ..., and the n-th group of salient poles. The salient poles in each group are arranged in the order of the first phase salient pole, the second phase salient pole, ..., and the q-th phase salient pole. The motor is a motor using the stator iron core with all phases of salient poles in concentrated arrangement. According to the invention, all phases of salient poles in the stator iron core are in concentrated arrangement, which can simplify the operation of the split-phase wiring and reduce interphase mutual inductance.

Description

【Technical field】 [0001] The invention relates to the field of motors, in particular to a stator core with concentrated arrangement of salient poles of each phase and a motor with concentrated arrangement of salient poles of each phase. 【Background technique】 [0002] The salient poles of each phase of the existing motor are arranged alternately, that is, a pair of magnetic pole coils of any phase must intersect with a pair of magnetic pole coils of another phase. The existing motor design theory has not yet focused on the arrangement of the salient poles of each phase. the design of. For permanent magnet motors or switched reluctance motors, the staggered arrangement of magnetic pole coils will make the phase-separated wiring work more complicated. Especially for switched reluctance motors, the salient poles of each phase are arranged alternately, and the yoke is a common magnetic circuit. When a single phase is energized, the mutual inductance between phases is relatively...

AI Technical Summary

Problems solved by technology

Especially for switched reluctance motors, the salient poles of each phase are arranged alternately, and the yoke is a common magnetic circuit. When a single phase is energized, the mutual inductance between phases is relatively weak. At this time, the flux linkage is relatively simple, and the control calculation is relatively easy. The phases have overlapping working areas, and the two phases need to share the yoke magnetic circuit and use the salient pole magnetic circuit interchangeably. At this time, a relatively serious mutual inductance between phases occurs, which makes the magnetic field extremely complicated and difficult to calculate accurately, which in turn leads to complex control strategies.
