Abstract
A direct drive reluctance machine is provided. An outer air gap is formed between the outer annulus of a rotor core and the inner annulus of an outer stator core formed by the stacking of silicon sheets; an inner air gap is formed between the inner annulus of the rotor core and the outer annulus of an inner stator core; keywalls are arranged in the inner annulus of the outer stator core and in the outer annulus of the inner stator core; the inner annulus of the outer stator core and the outer annulus of the inner stator core are respectively provided with an outer stator field copper and an inner stator field copper; a rotor cage of non-permeablility magnetic material is fixed on a shaft to support the rotor core; the shaft is embedded in the inner bore of the inner stator core through a bearing; a toroidal permanent magnet which is axially provided with a magnetic field is arranged in the lengthwise center of the rotor core and divides the rotor core into a left end iron core and a right end iron core; keywalls are respectively arranged in the inner bore and the outer annulus of the rotor core; the keywalls on the left iron core stagger one-half of tooth space with the keywalls on the right iron core circumferentially. The invention has the advantages of small cubage, light weight and reduced excitation consumption.
