Abstract

A controller-free self-startup permanent magnetism auxiliary synchronous reluctance machine relates to the motor field. At present, a general reluctance machine needs to be configured with a special-purpose controller to operate and does not have a self-startup operation function, at the same time, for a general permanent magnet synchronous motor, a lot of rare earth permanent magnetism materialsare adopted, so that the cost is higher. A rotor iron core of the present invention is formed by laminating the iron core punching sheets around and on which a plurality of magnetic poles surround andare distributed uniformly, the geometric center lines of the magnetic poles are the magnetic pole axes, and the rotating shaft holes are arranged in the centers of the iron core punching sheets. Theplurality of magnetic pole are all equipped with the permanent magnets which are arranged along the magnetic pole axes and of which the numbers are same, the reluctance grooves are arranged at the twosides of each permanent magnet, and a cast-in aluminum squirrel cage is arranged at the periphery of the rotor iron core located at the outer sides of the reluctance grooves of the iron core punchingsheets. According to the technical scheme, by adopting a mode of combining the permanent magnet synchronous motor and the synchronous reluctance machine, and combining the cast-in aluminum squirrel cage, the usage of the permanent magnetism materials is reduced, the motor can operate very well on the condition of not having a controller, and the cost of the motor is reduced substantially.

Description

technical field [0001] The invention relates to the field of motors, in particular to a self-starting permanent magnet assisted synchronous reluctance motor without a controller. Background technique [0002] At present, the general reluctance motor needs to be equipped with a special controller to operate, and has no self-starting operation function. At the same time, for the general permanent magnet synchronous motor, a large amount of rare earth permanent magnet materials are used, resulting in high cost. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the existing technical solutions, and to provide a self-starting permanent magnet assisted synchronous reluctance motor without a controller for the purpose of reducing costs. For this reason, the present invention takes the following technical solutions. [0004] A self-starting permanent magnet assisted synchronous...
