Conduct Research

A special type of brushless motor is called a limited-angle torquer (LAT). LATs are constrained to produce torque through a rotation angle of less than 180 . But they are widely used to operate servovalves, direct laser mirrors, position missile-guidance radar antennas, open shutters...
