Is there a Way to tell if a motor is trapezoidal wound? Besides trying it both ways and seeing which works best. I did try spinning the motor and looking at what the back EMF was with a scope, and what I saw on the screen looked like a smooth sine wave to me. But maybe that isn't a valid test.

Some newer motors vibrate a bit when the wrong waveform is used, but for a motion control situation with a fair bit of mass and friction, generally it is not bad.
