| Abstract: | As to the drive control problem of multiple motors, the inversed series connection rule of symmetrical six-phasePMSM two-motor system is proposed. For harmonic coupling problems, fictitious multi-machine coupling models of symmet.rical six-phase PMSM two-motor inversed-series connection system are established. The influence mechanism of the even-order harmonics in the symmetrical six-phase PMSM on the decoupling operation of the series system is revealed, and it ispointed out that the symmetrical design of the rotor structure can eliminate the harmonic coupling and realize its decouplingoperation. A variable load simulation is carried out on two symmetrical six-phase PMSM inversed-series connection systemwith symmetrical rotor structures, which proves the feasibility of decoupling operation of the system. |
