초록 ▼

A reaction force generating apparatus is provided which generates a reaction force for a rotationally operated member to be manually or mechanically operated. An alternating motor is provided that has a stator with three-phase coils; a rotor including permanent magnets; and a rotational axle extending from the center of the rotor and having a rotationally operated member attached to its one end. A direct voltage is supplied to the three-phase coils of the alternating motor, thereby producing a magnetic field on the stator. The magnetic field is oriented in one direction and cooperates with the permanent magnets to generate an electromagnetic attraction force for maintaining the operated member in a predetermined angular position. When the operated member is moved, a torque, or reaction force, is generated to restore the initial position of the operated member.
