<P>PROBLEM TO BE SOLVED: To provide a small motor with encoder assembled with high precision in which detection of the magnetic pole of a drive magnet in a small motor such as an AC servo motor is integrated with detection of the rotational position of a rotary shaft. <P>SOLUTION: The small motor with encoder comprises a motor body having a drive magnet and a drive coil opposing the drive magnet, and an encoder having a signal magnet with a magnetic signal of pole position of each pole of the drive magnet in the motor body and a magnetic signal of rotational position of a rotary shaft in the motor body being formed in the same plane wherein the magnetic signal of the signal magnet is formed in a plane intersecting the rotary shaft perpendicularly. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
