The single-phase capacitor-run induction motor is widespread for small power applications where the price is an important concern. In order to save costs, one tries to estimate the speed on the basis of voltage and current measurements and thus avoid a speed sensor. This paper deals with the rotor speed measurement on the basis of the capacitor voltage and proposes a low cost command device for a rolling shutter induction motor.
