MOTOR CONTROLLER (Cont’d)
Finally, the PWM modulated voltage generated by
the power stage is smoothed by the motor induct-
ance to get sinusoidal currents in the stator wind-
ings.
The induction motor being asynchronous, there is
no need to synchronize the rotor position to the
sinewave generation phase in most of the applica-
tions.
Part of the MTC dedicated to delay computation
and event sampling can thus be reconfigured to
Figure 75. Complementary PWM generation for three-phase induction motor (1 phase represented)

perform speed acquisition of the most common
speed sensor, without the need of an additional
standard timer.
This speed measurement timer with clear-on-cap-
ture and clock prescaler auto-setting allows to
keep the CPU load to a minimum level while taking
benefit of the embedded input comparator and
edge detector.
