Patent ID: 6933818

Claim:
A torque motor comprising: a rotor having at least two magnets disposed thereon, the magnets being arranged and constructed so that the outer surfaces thereof alternately have a N pole and a S pole, the magnets having a total magnet angle of less than 360 degrees, and a stator having a core and at least one coil, the core having a first and second magnetic pole elements facing the rotor and a connecting element interconnecting the first and second magnetic pole elements, the at least one coil being disposed on the connecting element of the core, wherein the magnetic pole elements are arranged and constructed such that an angle defined between a first straight line passing through a center of the first magnetic element and a center of rotation of the rotor and a second straight line passing through a center of the second magnetic element and the center of rotation of the rotor is less than 180 degrees so that the rotor has an effective operating angular range less than 180 degrees.
