Abstract
A motor and a motor speed control system are disclosed. Two power signal lines and one feedback/speed-control signal line are coupled between a control device and the motor. The two power signal lines electrically connect the control device to the motor. The feedback/speed-control signal line bi-directionally transmits signals coming from the control device to the motor and from the motor to the control device.
