Problems solved by technology

In addition, the existing linear switched reluctance motor has a low utilization rate of the iron core material due to the long yoke of the stator core, and the phase-to-phase insulation is required in the mover slot, so the utilization rate of the mover slot is low

Abstract

The invention discloses a dispersed magnetism-conducting block type straight-line switched reluctance motor with a single-side stator and a rotor with unequal tooth widths, comprising the stator and the rotor, wherein the stator comprises a stator engine base and a plurality of dispersed magnetism-conducting blocks; the dispersed magnetism-conducting blocks are fixedly arranged in the stator engine base; the stator engine base is provided with a single side and the stator is placed at one side of the rotor; the rotor comprises a rotor iron core; the rotor iron core is provided with rotor teeth, a rotor groove and a rotor yoke part; the tooth widths of the adjacent rotor teeth are unequal; the tooth widths of every other one rotor tooth are the same; and a rotor winding is placed in the rotor groove. The stator disclosed by the invention is the dispersed magnetism-conducting block so that a stator yoke part is omitted; the manufacturing process is simple, the use amount of an iron core material in a process of manufacturing a motor is reduced and the utilization rate of the iron core material is improved; the winding is a concentrated winding and a copper use amount of the end part is reduced; and each rotor groove is internally provided with one set of the winding so that inter-phase insulation is avoided and the utilization rate of the rotor groove is improved.

Description

technical field [0001] The invention relates to a linear switched reluctance motor, in particular to a linear switched reluctance motor with a single-side stator with unequal mover tooth widths and discrete magnetic conduction blocks. Background technique [0002] In the modern industrial production process, most advanced production processes require precise linear motion. To complete the linear motion, the traditional way is to convert the rotary motion into linear motion in the transmission conversion device, but the existence of the transmission conversion device has greatly increased The size of the transmission device is reduced, the reliability and efficiency of the system are reduced, and the equipment cost and maintenance cost are high. In addition, the transmission conversion device will significantly increase the vibration and noise of the transmission system, and reduce the control accuracy and performance of the system. In view of the above reasons, more and more...
