PROBLEM TO BE SOLVED: To provide a motor structure that minimizes damages to a permanent magnet, by improving a cooling power of a motor structure, and permits rapid starting and acceleration, obtains generation of high torques, and drives at ordinary temperature by supplying high values of electric current. SOLUTION: In a motor structure in which coils are wound on a coil bobbin, and the coil bobbin is housed within a case; the coil bobbin and the case are formed with thermal conductive non-magnetic materials. For instance, a rotor and a stator are housed within a case, and a refrigerant material is introduced so as to fill the interior of the case. For instance, a fin is provided to agitate the refrigerant material of the rotor. COPYRIGHT: (C)2005,JPO&NCIPI
