<p><P>PROBLEM TO BE SOLVED: To solve various constitutional problems such as displacement of an electromagnetic steel plate, by efficiently transmitting a torque generated at a rotor to a load. <P>SOLUTION: A ring coil motor includes: a stator unit 300 having a stator core 304 and a ring coil 310; a rotor unit 400 having a rotor core unit 401 with a rotor magnetic tooth 403 and a rotor magnetic pole 402, and a first and second rotor core holders 307, 308 mutually fixed tightly to sandwich end of the rotor core unit 401 from both sides in the radial direction, and disposed on the same axis as the rotor core unit 401. The rotor magnetic teeth 403 are formed of the electromagnetic steel plate, and the torque generated at the rotor unit 400 is transmitted to a rotational shaft through the rotor core holders 307, 308. An end surface 415 along the rotational axis of the rotor magnetic teeth 403 is made flat and continuous, and is brought into contact with the first rotor core holder 307 in the end surface 415. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
