sinusoidal trapezoidal back emf
hi peeps, can anyone tell me what the trade offs are for driving a trapezoidally wound motor with a sineusoidal controller? i have a trap motor and wanted to learn more about space vector modulation (because of its high DC bus utilization characteristics). this modulation technique will produce sine waves as an output, i wonder if i will really get any benifit from the modulation when it is applied to a trap motor. or will it even work? the feedback from the hall effect sensors will look trapezoidal instead of like a sine wave.. maybe the SVPWM won't even deliver sine waves output?
are there any research papers on this subject?
thx
