<p><P>PROBLEM TO BE SOLVED: To provide a rotary electric machine capable of efficiently generating a Lorentz force by increasing the rate of a current path where a magnetic flux passing through a magnetic material covering the current path is linked to a current with the shape of the magnetic material. <P>SOLUTION: A stator core 2 includes two disks 20a, 20b parallel with each other at both axial ends, and a stator coil 23. A rotor core 3 includes inner peripheral surfaces 31a, 31b, a first magnetic path 33a, a second magnetic path 33b, a coupling magnetic path 35, and a current path 37. A magnetic flux of the rotor core 3 by the first magnetic path 33a, second magnetic path 33b, and couling magnetic path 35 travels radially outward in the first magnetic path 33a and radially inward in the second magnetic path 33b. A current reflowing through the current path 37 flows through the first magnetic path 33a axially from below to above and also flows through the second magnetic path 33b axially from above to below. Consequently, the Lorentz force is applied peripherally in the same direction through the first magnetic path 33a and the second magnetic path 33b to efficiently generate a turning force. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
