Problems solved by technology

[0004] In an existing single-phase AC permanent magnet synchronous linear generator (public number: 109617361A), since the stator core is only laminated in the circumferential direction without block splicing, the processing cost is high, the core loss is large, and the quality of the stator is high. Large, poor heat dissipation condition of the motor

Abstract

The invention discloses a stator structure of a cylindrical linear motor. The stator structure comprises a motor shell, wherein the bottom of the motor shell is connected with a lower end cover through a fastener, a coil winding and a stator iron core are sequentially installed in a cavity of the motor shell, the top of the motor shell is connected with an upper end cover through a fastener, the stator iron core comprises a stator iron core block, and a plurality of stator grooves are formed in one end of the stator iron core block. The stator iron core is formed by laminating a plurality of silicon steel sheets along the circumferential direction, so that the eddy current loss of the stator iron core can be effectively reduced, the mass of the motor stator is reduced by means of partitioning of the stator iron core, the processing cost is reduced, the power density of the motor is improved, and the heat dissipation of the cylindrical linear motor is facilitated because a large numberof gaps exist between different blocks of the stator iron core.

Description

technical field [0001] The invention relates to a stator structure of a cylindrical linear motor, belonging to the technical field of linear motors. Background technique [0002] The linear motor can be considered to be evolved from the convenient conversion of the rotary motor. It can be seen as cutting a rotary motor radially, and then developing the circumference of the motor into a straight line. In this way, the original linear motor evolved from the rotary motor is obtained. The side evolved from the stator of the rotating motor is called the primary, and the side evolved from the rotor of the rotating motor is called the secondary. The radial, circumferential, and axial directions of the rotary motor correspond to the normal, longitudinal, and transverse directions of the linear motor, respectively. Sometimes the moving part of the linear motor is called the mover, and the stationary part is called the stator. [0003] The linear motor mainly has the following char...
