Abstract
An ice maker mechanism provides a position sensor sensing the position of the ice tray to allow control of absolute position of the ice tray without the need for motor stalling such as generates heat and wastes energy. An ice maker mechanism provides two motors for rotating the ice tray adapted for high torques low-speed rotation and low torque high-speed rotation the latter used for agitation of the water during freezing.
