Abstract
In a reluctance rotary electric machine, a movable part is arranged opposing part of an alignment of a plurality of stator poles to be movable in a predetermined direction. In the movable part, at least one pair of salient poles is configured to magnetically couple to the excited at least one first pair of the plurality of poles so as to form a first magnetic flux in loop thereamong. A segment magnetic-path portion is arranged to be magnetically separated from the at least one pair of salient poles. The segment magnetic-path portion works to magnetically couple therethrough between the at least one second pair of the plurality of stator poles so as to form a second magnetic flux in loop thereamong. The first magnetic flux and second magnetic flux create a reluctance force to move the movable part in the predetermined direction.
