TL;DR: In this paper, an electric motor, having a stator ( 465), a rotor ( 470), and an apparatus for evaluating a signal provided for controlling a motor (110), comprises a receiving unit (430, 440 ) for receiving a control signal (PWM_mod), which is a pulse width modulated signal onto which a data signal (DIR, DATA) is modulated.
Abstract: An electric motor, having a stator ( 465 ), a rotor ( 470 ), and an apparatus for evaluating a signal provided for controlling said motor ( 110 ), comprises a receiving unit ( 430, 440 ) for receiving a control signal (PWM_mod), which is a pulse width modulated signal (PWM) onto which a data signal (DIR, DATA) is modulated. An evaluation unit ( 440 ) is provided for evaluating the modulated control signal (PWM_mod). The unit is configured to extract, from the modulated control signal (PWM_mod), data provided for operation of the motor ( 110 ). The control apparatus includes a signal generator ( 450 ) configured to generate, on the basis of the extracted or ascertained data provided for operation of the motor ( 110 ), at least one control signal for the motor ( 110 ), such as a commanded direction of rotation. Piggybacking other control data onto the PWM power level signal reduces hardware investment, by permitting omission of a signal lead which would otherwise be required in the motor structure.
