Embodiment Construction

[0076] The present invention will be described in further detail below with specific embodiments in conjunction with the accompanying drawings.

[0077] according to figure 1 As shown, the present invention is composed of (single-slot) three-section compound stator poles and a radial-phase-splitting inner rotor three-phase 9 / 3-pole short magnetic circuit reluctance motor composed of a three-salient pole multi-arc boss rotor. It is a (single slot) compound stator pole L that is arranged radially and equidistantly distributed on the circumference of the continuous stator core 1. 1 L 2 L 3 L 4 L 5 L 6 L 7 L 8 L 9 The main and auxiliary magnetic poles are divided into three sections along the axial direction. The middle section is as long as the main magnetic pole, and is made of silicon steel sheets in the axial direction, and the two ends of the two sides are made of soft iron. Finally, they are combined by connecting technology to form a complete annular groove with - ...

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.
