Patent ID: 7723889

Claim:
A reluctance electric machine comprising: a stator core having a plurality of stator poles aligned in a predetermined direction with pitches therebetween; a plurality of multiphase windings installed in the stator core and configured to sequentially excite at least one first pair of the plurality of stator poles when energized, at least one second pair of the plurality of stator poles remaining between the excited at least one first pair of the plurality of stator poles; and a movable part arranged opposing part of an alignment of the plurality of stator poles to be movable in the predetermined direction, the movable part comprising: at least one pair of salient poles 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; and a segment magnetic-path portion arranged to be magnetically separated from the at least one pair of salient poles, the segment magnetic-path portion working 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 creating a reluctance force to move the movable part in the predetermined direction.
