Problems solved by technology

[0003] Although the switched reluctance motor has the advantage of maintaining high efficiency in a wide speed range, its efficiency is still low compared with the permanent magnet motor. How to reduce the iron loss and improve the efficiency of the motor is a hot topic in the research of the switched reluctance motor
In addition, the switched reluctance motor itself has the disadvantage of large torque ripple, so it is necessary to improve the mechanical strength of the stator
Furthermore, the existing reluctance motors have slots that are wider near the stator yoke and narrower near the tip of the stator, making the magnetic flux leakage between teeth and slots relatively large

Abstract

The invention discloses a block-type straight slot stator coil auxiliary brushless DC motor, which belongs to the technical field of reluctance-type doubly salient brushless DC Motors. The block-typestraight slot stator coil auxiliary brushless DC motor comprises a first stator, a second stator and a rotating shaft. A first rotor, a left magnetic conductive ring, a main magnetic conductive ring,a right magnetic conductive ring and a second rotor are sequentially arranged on the rotating shaft; the first stator and the second stator are connected through a plurality of magnetic conductive strips; the first stator corresponds to the first rotor; a first stator tooth of the first stator is provided with a centralized winding; the second stator corresponds to the second rotor; and a second stator tooth of the second stator is provided with a centralized winding. The block-type straight slot stator coil auxiliary brushless DC motor can improve the motor efficiency, improve the stator tooth strength, reduce the weight of the motor, and ensure the stable operation of the motor.
