2-magnetic-pole controller-free self-starting permanent magnet auxiliary synchronous reluctance motor

Abstract

The invention discloses a 2-magnetic-pole controller-free self-starting permanent magnet auxiliary synchronous reluctance motor, and relates to the field of the synchronous reluctance motor. At current, the reluctance motor can be only in operation by being equipped with a special controller, and needs a large number of rare earth permanent magnet material, so that the cost is high. The 2-magnetic-pole controller-free self-starting permanent magnet auxiliary synchronous reluctance motor comprises a machine base, a front end cover, a back end cover, a front bearing, a front bearing inner cover,a back bearing, a back bearing inner cover, a line stator, a rotor iron core, a rotary shaft, a bottom foot, a fan blade and a fan cover; the rotor iron core is formed by multiple iron core stampingsheets with two magnetic poles in an overlaying manner; rotary shaft holes are formed in the centers of the iron core stamping sheets; the two magnetic poles both comprise radially arranged reluctancegrooves of the same number; a fan-shaped permanent magnet is arranged in the middle of each reluctance groove; and an aluminum cast mouse cage is arranged on the periphery, on the outer sides of thereluctance grooves of the iron core stamping sheets, of the rotor iron core. By virtue of a combination of a permanent magnet synchronous motor and the synchronous reluctance motor in the technical scheme, and by combination of the aluminum cast mouse cage, use of a permanent magnet material is reduced, and high operation also can be realized without a controller, so that the motor cost is obviously lowered.

Description

technical field [0001] The invention relates to the field of synchronous reluctance motors, in particular to a 2-pole self-starting permanent magnet assisted synchronous reluctance motor. 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 provide a 2-pole self-starting permanent magnet assisted synchronous reluctance motor for the purpose of reducing costs. For this reason, the present invention takes the following technical solutions. [0004] A 2-pole non-controller self-starting permanent magnet assiste...
