Abstract
An actuator system having a controller, a motor, and a feedback device, wherein an output shaft of the motor is connected to the feedback device. The controller directs the application of power to the motor and the feedback device produces a signal indicative of the position of the output shaft. Advantageously, the signal may be read by the controller when the motor is not in motion.
Claims30
A system for driving a driven member, the system comprising:
- an actuator having a motor and a potentiometer, wherein the motor has an output shaft, a first drive contact and a second drive contact, and wherein the potentiometer has a first potentiometer contact, a second potentiometer contact and a potentiometer feedback contact, wherein the first potentiometer contact is connected to one of the first drive contact, the second drive contact and a grounded contact, the second potentiometer contact is connected to the potentiometer feedback contact, thereby producing a feedback signal indicative of a position of the output shaft;
- and
- a controller in communication with the actuator, wherein the controller has a feedback port, a first motor control port, and a second motor control port, the feedback port is connected to the second potentiometer contact and the potentiometer feedback contact, the first motor control port is connected to the first drive contact and the second motor control port is connected to the second drive contact.
A system for driving a driven member, the system comprising:
- an actuator having a motor and a means for producing a feedback signal, wherein the motor has an output shaft, a first drive contact and a second drive contact, and wherein the means for producing a feedback signal has a first contact, a second contact and a feedback contact, wherein the first contact is connected to one of the first drive contact, the second drive contact and a grounded contact, the second contact is connected to the feedback contact, thereby producing a feedback signal indicative of a position of the output shaft;
- and
- a controller in communication with the actuator, wherein the controller has a feedback port, a first motor control port, and a second motor control port, the feedback port is connected to the second contact and the feedback contact, the first motor control port is connected to the first drive contact and the second motor control port is connected to the second drive contact.
