Abstract
An inductor motor includes a stator block, a substantially cylindrical excitation coil, and a rotor including two substantially columnar magnet rotors coaxially arranged, and the magnet rotors are individually inserted inside two stator blocks coaxially arranged. The stator is formed of a substantially flat plate-shaped preformed member of a magnetic material having a plurality of protruding pieces circumferentially formed and protruding radially outwardly, and has stator teeth formed by bending the protruding pieces to stand up. The rotor has an intermediate circumferential groove with a smaller diameter than a magnet portion between the two magnet rotors coaxially arranged. A holding plate portion of the stator placed on an axially intermediate side in each stator block is placed around the intermediate circumferential groove of the rotor.
