Abstract

The invention discloses a dual-stator asynchronous starting cursor motor. The dual-stator asynchronous starting cursor motor comprises an external stator, an internal stator and a rotor, wherein the external stator comprises an external stator core and an external stator winding, the internal stator comprises an internal stator core, the rotor comprises a rotor core, a rotor damping winding, a rotor starting winding and permanent magnets, the external stator core is an annular shape and is used for accommodating the external stator winding, the rotor core coaxially sleeves the external statorcore, the top of a rotor groove is used for accommodating the rotor damping winding, the bottom of the rotor groove is used for accommodating the rotor starting winding, the internal stator core coaxially sleeves the external stator core, the difference of an internal stator groove in space is a mechanical angle of half groove pitch, and a plurality of permanent magnets are arranged in the rotor core. The dual-stator asynchronous starting cursor motor provided by the invention employs the two stators, the rotor employs two sets of rotor windings, the breakage of the permanent magnets on a magnetic path during starting and in a steady state can be prevented, the starting performance can be ensured, and the steady-state performance also can be compatible.

Description

technical field [0001] The invention belongs to the technical field of motors, and more specifically relates to a double-stator asynchronous starter vernier motor. Background technique [0002] my country is rich in rare earth resources, and the research level of rare earth materials and rare earth permanent magnet motors has reached the international advanced level. Therefore, giving full play to the advantages of rare earth resources, vigorously researching and promoting the application of various permanent magnet motors represented by rare earth permanent magnet motors has important theoretical significance and practical value for our country. Compared with traditional asynchronous motors, permanent magnet motors are simple in structure and reliable in operation; small in size and light in weight; low in loss and high in efficiency; the vernier motor has the advantage of high torque density, and its torque density can reach that of ordinary permanent magnet motors more t...
