Abstract: A motor speed controller ( 100 ) identifies the position of a pump rod ( 14 ). At one or more critical positions of the rod, the motor speed controller ( 100 ) adjusts the speed of the motor to change the movement of the pump rod ( 14 ). The critical positions and the rate of change of speed at each critical position can be user-specified.
