SimplIQ Software Manual Commutation
MAN-SIMSW (Ver. 1.4)
8-13
Most motors are wound to sinusoidal or trapezoidal winding forms, but no motor can be
exactly sinusoidal or trapezoidal. Trapezoidal motors are normally chosen for six-step
commutation, whereas sinusoidal motors are normally chosen for continuous commutation.

8-4: Winding Shape Function for Sinusoidal Motor
In order to optimize the SimplIQ drive for as many motors as possible, the SimplIQ drive can
be programmed to any winding shape function.
SimplIQ drives come from the factory
programmed, by default, for sinusoidal motors, but the motor waveform can be changed
using the Composer program.
