Abstract
The invention discloses a variable reluctance motor and a rotor structure thereof. A stator portion of the variable reluctance motor comprises a plurality of E-shaped stator segments; and an inner circular surface of the stator is in a cylindrical surface shape or a drum shape. A rotor portion is an annular eccentric rotor in a cylindrical shape or a drum shape; the ring-type eccentric rotor in the cylindrical shape includes an inner ring and an outer ring, wherein the outer ring is a magnet collecting ring. The magnetic collection capability of the outer ring of the ring-type eccentric rotor in the cylindrical shape is utilized, thereby reducing the magnetic flux leakage and improving efficiency. When a load works, magnetic forces generated between the ring-type eccentric rotor in the cylindrical shape and the E-shaped stator segments are mostly used for working. Meanwhile, because the direction of the magnetic field of the stator is almost not changed, the iron loss is substantially reduced; due to application of the radial force to the working and the structure of the ring-type eccentric rotor in the cylindrical shape, the output torque, compared with that of the traditional variable reluctance motor, is more stable and thus the vibration and noises are reduced. In addition, the ring-type eccentric rotor in the cylindrical shape has the light weight and the dynamic performance of the rotor is superior to that of a traditional switch reluctance motor.
