Abstract

The invention discloses a magnetic ring stator cylindrical linear switch reluctance motor which comprises a stator cylinder and a rotor cylinder. The stator cylinder comprises a stator magnetic ring and a non-magnetic stator sleeve, the stator magnetic ring is fixed to the non-magnetic stator sleeve or is coaxially spliced with the non-magnetic stator sleeve, and the stator cylinder is formed. The rotor cylinder comprises a rotor iron core, the rotor iron core is formed in a one-off mode or is formed by splicing a plurality of parts in the axial direction, rotor teeth, an annular rotor groove and a concentric rotor winding which is arranged in the annular rotor groove and winds around the axle wire of the rotor cylinder are arranged on the rotor iron core. According to the magnetic ring stator cylindrical linear switch reluctance motor, a stator yoke portion is omitted, the using amount of materials for manufacturing the iron core of the motor is reduced, the utilization rate of the iron core materials is improved, insulation between phases for the rotor groove is omitted, manufacturing technologies are simplified, utilization rate of the grooves is improved, and the magnetic ring stator cylindrical linear switch reluctance motor has the advantages of being high in propulsion density, simple and reliable in structure and the like.

Description

technical field

[0001] The invention relates to a cylindrical motor, in particular to a cylindrical linear switched reluctance motor with a magnetic conduction ring stator. Background technique

[0002] The linear motor directly converts electrical energy into mechanical energy of linear motion, which not only omits the intermediate transmission mechanism, but also reduces system loss, and is very suitable for linear direct drive systems.

[0003] The flat linear motor is an open flat structure with both ends broken. There are transverse breaks on both sides of the motor core, which has obvious lateral edge effects, resulting in discontinuous distribution of the magnetic field in the motor and affecting the operating performance of the motor. The winding mode of the flat linear motor is similar to that of the rotary motor, and there are end windings. When the length of the iron core is long and the distributed winding form is used, the utilization rate of the winding is low,...
