Abstract:
 Aiming at the decouple operating of double Y shift 30° permanent magnet synchronous motor
( PMSM) series-connected system driven by generalized zero-sequence harmonic,the Fourier transform
expressions of double Y shift 30° PMSM concentrated winding function are setup,and the magneticmotive
force( MMF) expressions of couple relation between the series-connected two motor are achieved. The influence
laws of high order space harmonic of PMSM on decouple operating for the series-connected system
were researched. The multi-dimension space mathematic models of PMSM1 containing 5th and 7th harmonics
were setup. The simulating analysis of variable speed and variable loads was proposed,which
shows the couple effects of the 5th and 7th space harmonics. The essential requirement of stator winding
design for the series-connected system decouple control was revealed.
