<P>PROBLEM TO BE SOLVED: To provide a magnetic motor which can easily fix a magnetic sensor to an optimum position without limiting movement and mounting range of the magnetic sensor due to the presence of a coil, and which can optimally control an energization of the coil. <P>SOLUTION: The magnetic motor is partitioned to a plurality of regions I, II and III at an equal interval in a circumferential direction. The respective regions of the motor include a part in which a plurality of permanent magnets are aligned and a part in which a permanent magnet is not installed, and rotors 4, 5 disposed obliquely to a radial line extended from a rotary axis to an outside are mounted on a rotary shaft 6 in the permanent magnet. An auxiliary rotor 24 having the same constitution as the rotors 4, 5 is mounted at the end of the rotary shaft 6, and the magnetic sensor 25 is provided at the outside of the auxiliary rotor 24 in the circumferential direction. <P>COPYRIGHT: (C)2004,JPO |
