Abstract
Abstract A reluctance rotary machine comprises stator coils (16) including a winding phase for being supplied with a 90°-leading armature current to generate a no-load induced electromotive force, and a substantially I-shaped rotor (14) disposed in the stator coils and having an extremely small magnetic reluctance in a first direction normal to a rotational axis and a large magnetic reluctance in a second direction normal to the first direction, the substantially IU-shaped rotor being constructed of silicon steel having a small magnetic reluctance.
