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
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.
