<P>PROBLEM TO BE SOLVED: To provide a magnetic inductor type rotary motor capable of suppressing the influence of a magnetic field generated by a drive coil for generating torque, and improving detection accuracy of a rotation position of a rotor by a magnetic sensor. <P>SOLUTION: A magnetic inductor type rotary motor 1 comprises: a stator core 8 composed of first and second stator cores 9 and 10, separated at a predetermined distance in an axial direction, and teeth 9b and 10b arranged coaxially by matching circumferential positions thereof; stator coils 11 concentratedly wound around each pair of the teeth 9b and 10b, facing in the axial direction; a rotor 3 including first and second rotor cores 4 and 5, positioned in an inner peripheral side of the first and second stator cores 9 and 10, respectively, which rotor cores are coaxially fixed on a rotating shaft 2 by shifting the first and second rotor cores 4 and 5 by a half salient pole pitch in a circumferential direction; a field coil 12 interposed between the first and second stator cores 9 and 10; and a magnetic sensor 14 arranged between the teeth 9b and 10b, facing in the axial direction, for detecting a magnetic flux change flowing between the teeth 9b and 10b in the axial direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
