Abstract

The invention relates to a single-phase cylindrical switch-reluctance linear motor. The single-phase cylindrical switch-reluctance linear motor comprises a motor stator part, a motor rotor part and a linear bearing, wherein the motor stator part comprises a stator sleeve and a winding coil, an annular stator groove is formed in the stator sleeve, two planes of the stator sleeve are stator teeth, arc-shaped grooves are formed in the two stator teeth, one cambered-surface plate of the stator sleeve is a stator yoke part, and the stator teeth and the stator yoke part are formed in an integrating manner; the motor rotor part comprises three rotor tooth circular rings and a rotor yoke sleeve. According to the single-phase cylindrical switch-reluctance linear motor, the manufacturing process is simplified, and the utilization rate of a groove is improved; furthermore, the propelling force of a rotor is increased, the sealing performance is good, the structure is simple and firm, an end effect and a normal magnetic pull force of the motor are eliminated, the reliability of the motor is high, and requirements on a movement location of reciprocating linear vibration can be met; the single-phase cylindrical switch-reluctance linear motor is suitable for popularizing industrial linear oscillation.

Description

technical field

[0001] The invention relates to a linear motor, in particular to a single-phase cylindrical switched reluctance linear motor for linear vibration. Background technique

[0002] Linear motor is a transmission device that can directly and quickly convert electrical energy and mechanical energy generated by linear motion. Since the linear motor does not need an additional device to change the rotary motion into a linear motion, the structure of the system itself is greatly simplified, and the quality and volume are reduced. In the field of linear drive, linear motors can be directly driven, which can eliminate various positioning errors caused by intermediate links. There are various structures of linear motors. As a motor with a special structure, cylindrical linear motors are the structural evolution of ordinary rotating motors. Cutting and straightening the rotating motors along the radial direction can obtain flat linear motors. The motor, and then the fla...
