Abstract

The invention relates to a double stator-rotor multiple-pole switching reluctance motor. The motor comprises a stator and a rotor, which are laminated by silicon steel sheets and have double salient structures, wherein iron cores of the stator and the rotor consist of two sections respectively, lengths and diameters of the two sections of the iron core of the stator are the same as those of the iron core of the rotor; two sets of concentrated windings or layer windings are respectively arranged on teeth of the two sections of the stator; and armature windings on two teeth at the same phase position of each set of windings are connected in series or in parallel to form a phase. The motor is characterized in that: magnetic poles of the two sections of the stator are aligned, and the magnetic poles of the rotor are different from the stator by a 1/2 stator pole angle; or the two sections of the rotor are aligned, and the two sections of stators are different by a 1/2 stator pole angle. The pole number of the stator is twice of that of the rotor, and pole numbers of the stator and the rotor are an even number combination, so the motor solves the problem that a plurality of grooves and a plurality of poles cannot be manufactured in the traditional switched reluctance motor, and has the characteristics that: the cost is low, the efficiency is high and the motor is easy to control.

Description

technical field [0001] The invention relates to a switched reluctance motor, in particular to a double-stator-rotor double-pole switched reluctance motor. Background technique [0002] At present, the switched reluctance motor is a double-salient switching motor, and its stator poles are wound with concentrated windings; the motor can be divided into 3-phase, 4-phase and multi-phase switched reluctance motors according to the number of phases, of which 3 Phase 6 / 4, 12 / 8, 4 phase 8 / 6 structures are mostly, switched reluctance motor has simple structure, easy to manufacture, easy to adjust speed, reliable operation, not easy to damage, high power factor, high operating efficiency, large starting torque , small starting current, strong overload capacity, heavy load starting and other advantages, and at the same time, it has good performance in a wide range of high-speed constant power range. [0003] As the number of phases and poles of the switched reluctance motor increases,...
