Abstract

The invention provides a four-electrical port brushless double-fed motor with a reluctance rotor and double stators. The motor comprises two stators and the reluctance rotor which are an outer stator (1), an inner stator (5) and the reluctance rotor (3) and concentrically arranged from outside to inside; an inner air gap (2) is arranged between the inner stator (5) and the rotor (3); an outer air gap (4) is arranged between the outer stator (1) and the rotor (3); the outer stator (1) comprises an outer stator yoke (6), outer stator teeth (7), an outer power winding (8) and an outer control winding (9); the inner stator (5) comprises an inner stator yoke (10), inner stator teeth (11), an inner power winding (12) and an inner control winding (13); the outer control winding (9) of the outer stator (1) and the inner power winding (12) of the inner stator (5) form a work group; the outer power winding (8) of the outer stator (1) and the inner control winding (13) of the inner stator (5) form another work group; and the rotor (3) comprises magnetic conductive blocks (14) and non-magnetic conductive blocks (15) which are uniformly distributed along the circumference.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a brushless double-fed motor with reluctance rotors, double stators and four electrical ports. The motor can be used not only as a variable frequency speed regulating motor, but also as a variable speed constant frequency generator. The rotor of the motor has no winding and no permanent magnet, and has simple structure and high mechanical strength. The motor has four sets of windings, forming four electrical ports. Background technique [0002] Today, environmental pollution, fossil energy shortage, ecological deterioration and a series of problems threatening human survival are becoming more and more prominent. The use of fossil fuels is at stake here. In order to create an ecologically harmonious and sustainable environment suitable for future survival, it is very important to improve the traditional fossil energy-based energy supply structure. There are various forms of cle...
