Clean Motor Output Wave
As a result of the five-
level PWM control, the
output current waveform
is close to a sine wave.
Harmonic currents in
the motor windings are
minimized so the heat
loss is negligible and
there is very little shaft
torque ripple. Illustrated
waveform is from the
similar TMdrive XL85 test.
