Abstract

The invention provides a block rotor-type double-stator variable flux reluctance motor, which comprises an outer stator, an inner stator and an odd number-pole rotor, wherein the odd number-pole rotor is clamped between the outer stator and the inner stator and is prepared from an odd number of magnetic conductive materials; the inner stator is coaxially connected with the outer stator; each tooth of one of the inner stator and the outer stator is wound by an AC armature winding and a DC exciting winding which are driven by sine-wave current; an outer-layer air gap is arranged between the outer stator and the rotor; and an inner-layer air gap is arranged between the inner stator and the rotor. The number of rotor poles of the motor is the odd number; the output torque ripple is small; and the radial unbalanced magnetic pull of the odd number-pole rotor is obviously inhibited or even eliminated.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a block-rotor double-stator variable-flux reluctance motor. Background technique [0002] Because of its simple structure, reliable operation and low cost, switched reluctance motors are widely used in industrial, aviation and household circuits. But it also has obvious disadvantages, such as: low torque density, large torque ripple and large noise. [0003] In order to improve the performance of switched reluctance motors, IEEE Transactions on Magnetics, Issue 6, 2013, Volume 49, pages 3020-3028, "Electromagnetic Performance of Novel Variable FluxReluctance Machines With DC-Field Coil in Stator" proposes a stator for each A variable flux reluctance motor with DC field windings and AC armature windings wound on each tooth, and the rotor is a salient pole rotor of an ordinary switched reluctance motor, IEEE Transactions on Energy Conversion, Issue 99, PP Volume 1-1...
