Also, I have made a motor controller which matches that 5th harmonic component to eliminate the torque ripple. Not sure if it matters a whole lot in the end, but it is definitely an interesting project. However, if you're saying that nobody else ever does that, that would answer the part of my question about what drive waveforms the typical numbers are measured with. | |

To compare your measurements to the spec, it would be useful to know the speed you made them at, and load (if any). Re: drive waveforms; you can eliminate any suggestion that any driver would simulate a specific 5th harmonic component, but a trapezoidal waveform may happen to have some. | |
