Method And Apparatus For Measuring Speed Of A Brush Motor

View page
US Patent:
20120330595, Dec 27, 2012
Filed:
Jun 11, 2012
Appl. No.:
13/493665
Inventors:
Stefan Mark Atay - Lexington KY, US
International Classification:
G01P 21/00
US Classification:
702 96
Abstract:
A system for determining motor speed of a brush DC motor in an apparatus, including circuitry for sensing current in the brush DC motor; a first filter for receiving a substantially DC component of the sensed current and parameters corresponding to the brush DC motor, for calculating a speed estimate thereof; an adaptive bandpass filter having a center frequency corresponding to the speed estimate of the first filter, for receiving the sensed current and substantially isolating a periodic current fluctuation thereof; a block for determining a frequency of the periodic current fluctuation, the periodic current fluctuation frequency being a commutation frequency of the brush DC motor and corresponding to motor speed of the brush DC motor. The motor speed determined from the periodic current fluctuation of the motor current is then used to control the speed of the motor.

US Patent:
20120326704, Dec 27, 2012
Filed:
Jun 11, 2012
Appl. No.:
13/493754
Inventors:
Stefan Mark Atay - Lexington KY, US
International Classification:
G01P 3/48
G01P 3/46
US Classification:
324177
Abstract:
A system for determining motor speed of a brush DC motor, including a first filter for receiving a substantially low frequency portion of a sensed current of the motor and parameters corresponding thereto, for calculating a speed estimate of the motor; an adaptive bandpass filter having a center frequency corresponding to the speed estimate of the first filter, for receiving the sensed current and substantially isolating a first periodic current fluctuation thereof. A detected frequency of the first periodic current fluctuation corresponds to the speed of the brush DC motor. The system may include a tracking frequency selection block for selecting a frequency component of the sensed current and providing same to the first filter, wherein the speed estimate is based in part upon the selected frequency component.

US Patent:
20120326705, Dec 27, 2012
Filed:
Jun 11, 2012
Appl. No.:
13/493777
Inventors:
Stefan Mark Atay - Lexington KY, US
International Classification:
G01P 3/48
US Classification:
324177
Abstract:
A system for determining motor speed of a brush DC motor in an apparatus, including a first filter for receiving a substantially DC component of the motor current and parameters corresponding to the brush DC motor, for calculating a speed estimate thereof; an adaptive bandpass filter having a center frequency corresponding to the speed estimate of the first filter, for receiving the motor current and substantially isolating a periodic current fluctuation thereof; a block for determining a frequency of the periodic current fluctuation, the current fluctuation corresponding to motor speed of the brush DC motor. The adaptive bandpass filter uses debounce filtering to reduce rapid filter passband switching, and a run-in period prior to passband switching to obviate transient effects of filter switching.
