Title:
RIPPLE COUNT CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2019/137934
Kind Code:
A1
Abstract:
A motor control system includes a variable voltage supply in signal communication with a direct current (DC) motor. The DC motor includes a rotor induced to rotate in response to a drive current generated by a variable supply voltage delivered by the voltage supply. The rotation of the rotor (103)generates a mechanical force that drives a component. A ripple count circuit (104)is configured to filter the drive current based on a rotational speed (ω) of the rotor (103), and to generate a pulsed output signal indicative of the rotational speed (ω) of the rotor and a rotational position (θ) of the rotor.
