Short magnetic circuit reluctance motor, and double stator magnetic poles, rotor core and wound rotor

Abstract

The invention discloses a short magnetic circuit reluctance motor, and double stator magnetic poles, a rotor core and a wound rotor. The three-phase 9 / 3 pole short magnetic circuit reluctance motor divides nine groups of double stator magnetic poles distributed on the circumference of a stator (1) at equal intervals into three sections in axial direction, wherein the length of the middle section is equal to that of a main magnetic pole and the middle section is manufactured by overlapping silicon-steel sheets; other main and auxiliary magnetic poles are manufactured into appropriate shapes by soft iron so that the three sections of main and auxiliary magnetic poles can be formed into the double stator magnetic pole with an annular groove for placing exciting windings after being combined together; then, the nine exciting windings (L1, L2, L3, L4, L5, L6, L7, L8 and L) are respectively arranged in each annular groove to obtain three-phase exciting windings (L1, L4, L7 and L2, L5, L8 and L3, L6, L9) on the circumference of the stator (1) in turn according to the rule of equilateral triangles; and then, a three-salient pole rotor core (3) consisting of a multi-cambered surface lug boss is arranged on a hollow rotor shaft lever (4) with internal thread and forms rotating connection with a stator part through a periphery connecting and fixing device of a motor.
