Abstract

The invention discloses a 9n/10n pole segmented rotor switched reluctance motor. The motor stator teeth number is 9n, the rotor teeth number is 10n, the phase number is 3, and n is a natural number; The stator teeth comprise 3n wide teeth and 6n narrow teeth, one coil is wound on each wide tooth, and a wireless loop on the narrow tooth; The wide teeth are evenly distributed on the circumference ofthe wide teeth, and the difference is 120 DEG/n; 2 narrow teeth are arranged between the wide teeth and the wide teeth, each narrow tooth is 36 degrees/n different from its adjacent wide teeth, and the adjacent two narrow teeth are 48 degrees/n different from each other; The rotor is composed of 10n rotor iron cores and one non-magnetic permeable support frame, and the rotor iron core is fixed onthe non-magnetic permeable support frame; Each phase magnetic circuit is of short magnetic circuit structure, the loss of iron core is small, and the magnetic circuits between the phases are not coupled, and the windings are isolated from each other. The invention has the advantages of strong starting ability, small torque ripple, small wind resistance loss, small vibration noise, high reliability and fault tolerance.

Description

technical field [0001] The invention relates to a 9n / 10n pole segmented rotor switched reluctance motor, which belongs to the technical field of motor-type switched reluctance motors. Background technique [0002] The stator and rotor of the switched reluctance motor are double-salient pole structures, and the rotor has no windings and permanent magnets. It has the characteristics of simple and firm structure, low cost, high temperature resistance and high-speed adaptability. It is widely used in civilian fields. [0003] However, due to the salient pole structure of the rotor, the wind loss of the switched reluctance motor is greater, and the problem of vibration and noise is further aggravated, which weakens its application in the field of low noise. To this end, people have proposed a segmented rotor switched reluctance motor (Segmented Switched Reluctance Motor), in order to reduce wind resistance loss and reduce noise. The rotor of the motor has a cylindrical structur...
