Abstract

A coil mutual-induction coupled linear switch reluctance motor comprises a primary pole and a secondary pole. The primary pole consists of iron cores which are laminated by a distributed multi-phase armature winding and a silicon steel sheet. The secondary pole is laminated by silicon steel sheets without winding. The primary pole and the secondary pole have salient pole structures. Pole numbers of the primary pole and the secondary pole and the rotation switch reluctance motor can be made into the forms such as 4 / 6 pole and 8 / 12 pole. The structure form can be one-sided or two-sided, can be a moving coil type or a moving iron core type. A motor winding is a distributed winding. The three-phase windings are mutually inducted and coupled. Two-phase excitation always exists in any working time. The reluctance motor solves the problems of low winding utilization rate and low motor power density of present linear switch reluctance motors and can be used as a motor also as a generator.

Description

technical field [0001] The invention belongs to a switched reluctance linear motor in the field of linear motors, in particular to a linear switched reluctance motor with coil mutual inductance coupling. Background technique [0002] The primary winding of the traditional linear switched reluctance motor is a concentrated winding, and only one phase is excited at any time during operation, so the utilization rate of the winding is low, the power density of the motor is low, and the mutual inductance between the windings is independent. Contents of the invention [0003] In order to solve the problems of low winding utilization rate and low motor power density of the existing switched reluctance motor, the present invention provides a linear switched reluctance motor with coil mutual inductance coupling that can make full use of materials and has high power density. [0004] In order to achieve the above-mentioned purpose, the technical scheme adopted by the present inventi...
