Patent number: 11923850Abstract: A motor control system includes a DC motor and a ripple count circuit. The DC motor includes a rotor that rotates in response to a drive current. The rotation of the rotor generates a mechanical force that drives a component. The ripple count circuit includes an active filter circuit and a parasitic pulse cancellation circuit. The active filter circuit is configured to filter the drive current and to generate a pulsed signal. The parasitic pulse cancelation circuit is in signal communication with the ripple count circuit to receive the pulsed signal and generates a ripple count signal that excludes parasitic pulses included in the pulsed signal having a parasitic voltage level that exceeds a voltage level of a voltage threshold. The parasitic pulse cancelation circuit actively adjusts the voltage level of the voltage threshold based at least in part on a rotational direction of the rotor.Type: GrantFiled: April 7, 2022Date of Patent: March 5, 2024Assignee: INTEVA PRODUCTS, LLCInventor: François Breynaert

Publication number: 20220416705Abstract: A ripple circuit includes a sensor, and oscillator circuit and a logic gate. The sensor monitors operation of a motor that is powered by a power signal provided by a motor circuit. The sensor outputs a data signal having a first state or a second state based on the operation of the motor. The oscillator circuit generates an oscillating signal having a fixed frequency. The logic gate includes at least one input in signal communication with the sensor and the oscillator circuit and at least one output in signal communication with the motor circuit.
