Abstract

The invention discloses a synchronous reluctance motor. The synchronous reluctance motor comprises a stator and a rotor, and is characterized in that the stator comprises a stator core and a winding wound in a stator groove, the winding is an external star-shaped and internal triangular mixed winding, the star-shaped and internal triangular mixed winding is in serial connection, and the number ofturns of a coil of a triangular winding is twice that of a coil of a star-shaped winding. According to the synchronous reluctance motor, the star-delta hybrid winding is adopted, and compared with anexisting traditional star-shaped winding synchronous reluctance motor, the winding coefficient of the motor is increased, the fifth harmonic content and the seventh harmonic content are reduced, the output torque of the synchronous reluctance motor is increased, and the efficiency and the power factor are increased.

Description

technical field [0001] The invention relates to a motor, in particular to a synchronous reluctance motor. Background technique [0002] With the continuous reduction of fossil fuel resources in the world today, and the emphasis of various countries on environmental protection and sustainable development, energy conservation and consumption reduction has become an important issue of common concern to the international community. High-efficiency motor products are of great significance to environmental protection, energy-saving emission reduction, and sustainable economic and social development. Synchronous reluctance motors have advantages such as low cost, simple structure, high reliability, and high efficiency, and have great potential in the field of high-efficiency energy-saving motors. . [0003] In recent years, with the continuous increase of primary energy consumption and the enhancement of people's awareness of environmental protection, high-efficiency and energy-sa...
