Abstract
A 2-D pointer motor provides for panning (sideways actuate motion) and tilt (yaw motion) and may be made smaller than one-cubic inch. The motor is preferably controlled by a microcomputer based controller using pulse-width modulation (PWM) to separately control each of its three coils. The coils are arranged orthogonally to provide a single unified torque vector which turns the rotor and accurately points it in the desired directions. The motor is especially adapted to carry a sensor such as a CCD array.
