The application discloses a linear-rotary low-speed cylindrical motor, and relates to the motor technology suitable for low-speed ocean wave power generation. A linear-rotary low-speed cylindrical generator, including a stator, a rotor and a mover installed from outside to inside, separated from each other by an air gap. The stator includes a stator core formed by laminating a plurality of U-shaped silicon steel sheets, a stator permanent magnet inserted into the middle of the stator core and alternately magnetized radially along the circumference, and a stator core wound on the stator core and the stator permanent magnet. Stator winding; the rotor includes a plurality of discrete rotor cores, and the inner wall of each rotor core is covered with rotor permanent magnets alternately magnetized in the radial direction; the mover is composed of a whole soft magnetic material, The outer peripheral wall has a plurality of protruding teeth distributed along the axial direction. Compared with the traditional cylindrical motor, the motor described in this application has simple heat dissipation, simple processing, longer stroke and lower cost, especially the flux linkage frequency of the turn chain in the stator winding is higher than the frequency of the linear motion of the mover, realizing Frequency amplification function.
Description
technical field [0001] The present application relates to the technical field of motors, in particular to a linear-rotating low-speed cylindrical generator. Background technique [0002] The traditional direct-drive wave power generation system generally uses a traditional cylindrical linear motor with a short stroke, which directly converts the kinetic energy of the linear reciprocating motion of the mover into the primary winding to generate electrical energy for external power generation. Due to the low motion speed of the sea waves, the frequency of the generated alternating current is low, which increases the subsequent rectification loss. Simultaneously, the reciprocating motion stroke of sea wave is long, can't make full use of its kinetic energy. However, considering the mechanical strength, processing difficulty and manufacturing cost, the pole distance of the mover cannot be further reduced, it is difficult to increase the frequency, and the stroke of the mover ca...
