ABSTRACT:
A wireless encoder system facilitates operation and control of a motor, such as linear motor. The system includes an encoder sensor moveable with a first part of the motor. The encoder sensor is operative to sense movement of the first part relative the second part and provide an encoder signal having an electrical characteristic indicative of the sensed movement. A transmitter, which is associated with the encoder sensor, is operative to transmit a wireless transmitter signal based on the encoder signal. A remote receiver that receives the wireless transmitter signal thus may determine position and/or movement of the first part of the motor relative to a second part of the motor.
