Abstract

A magnetic flux modulation dual-stator dual-electric port motor, including coaxially arranged and independent of each other: a first stator, a second stator, a freely rotatable magnetic modulation ring connected to a driving component for torque transmission, the first stator There is an air gap between the first stator and the second stator, and the magnetic modulation ring is set in the air gap between the first stator and the second stator or sleeved on the outside of the first stator and the second stator so that the first stator and the second stator The magnetic field generated by the two stators is modulated. The first stator is equipped with the first stator winding with the number of pole pairs P1, and the second stator is equipped with the second stator winding with the number of pole pairs P2. The magnetic modulation ring includes N magnetic permeable blocks arranged at intervals, and P1+P2=N, P1, P2, and N are positive integers. The magnetic flux of the present invention converges into the air gap between the stator and the magnetic modulation ring, which can improve the torque transmission capacity and transmission efficiency, and in the case of P1+P2=N, can realize the maximum torque transmission capacity, two sets of independent Stator windings allow flexible four-quadrant control.

Description

technical field [0001] The invention relates to the field of motor and transmission technology, in particular to a magnetic flux modulation double stator double electric port motor. Background technique [0002] Flux modulated motors mainly include permanent magnet motors and double-fed reluctance motors. [0003] The working principle of the permanent magnet motor based on the principle of magnetic field modulation is described in detail in the patents CN102035320A, CN102355120B and CN102324820A. Through the analysis of the working principle of the modulated permanent magnet motor, it can be known that the core component to realize the work of this kind of motor is the magnetic block unit. Rotate the harmonic magnetic field to generate a constant electromagnetic torque to make the outer rotor of the motor rotate at a lower speed. The drive system produced by the direct combination of the magnetic gear and the external rotor of the traditional permanent magnet motor has a ...
