Abstract
A permanent magnet type motor primarily includes ring stator core 22, the stator 21 with many stator windings 1U, 1V, 1W, 2U, 2V, 2W around the core 22, and numerous permanent magnets 28, 30 housed in the interior of the rotor core 26. By means of the space of stator 22 and the freely rotating rotors maintaining a fixed gap 29 with the inner surface, the stator windings 1U, 1V, 1W, 2U, 2V, 2W are conducted with current so that the rotors 24 can be rotated. It is characterized by that the permanent magnets 28, 30 of rotor 24 are shaped with arc cross section, in addition, the permanent magnets 28, 30 are installed in rotor core 26 so as to face the protruded portion 28a, 30a toward the rotation center axis of rotor 24. All portions of permanent magnets 28, 30 are magnetized to generate the readily magnetization orientations, which generate the distribution of the radiation directions from certain center point C over the curvatures center side of the permanent magnets 28, 30. The distance L, from the point C to the center axis of the center along the thickness direction while passing the permanent magnets 28, 30, and the average curvature radius R of the permanent magnets 28, 30 can be correlated with the following relationship: 1.0 x R {SYMBOL 163 \f "Symbol"} L {SYMBOL 163 \f "Symbol"} 7.5 x R
