Attached is a waveform of one winding of a three phase trapezoid drive
motor with another phase PWM drive on the bottom. This 3 phase 4 pole motor
is rotating at 1500 RPM with 120Vdc, 20KHz and about 8.0 amps peak on each
winding. My drive electronics but someone else's (enemy) software.

My question, does that current waveform, on top, look correct? At 3k RPM it
screams. Should not the top portion and bottom be similar?
