摘要： A rotary machine comprising a stator having magnetic poles each provided with a stator winding, and an armature mounted for rotation within said stator and provided with an armature winding. Each of said magnetic poles is integrally formed at the end thereof with two oppositely directed polepieces which are aligned along the surface of said armature with a gap therebetween, said two polepieces being bisymmetrical so as to provide a larger sectional area of the magnetic path through a trailing one of said two polepieces in the rotating direction of the armature than that through a leading one of said two polepieces, whereby the output capacity of the rotary machine is increased.

摘要： A system for propelling a train by a linear synchronous motor comprising a group of propelling coils disposed in pairs along a train track on the ground on opposite sides of the center line of the train track and opposite to field coils mounted on the vehicle with a predetermined gap defined therebetween, said coil pairs in the propelling coil group being connected in parallel respectively to constitute a group of short-circuited coil units which interact electro-magnetically with the field coils to stabilize the vehicle against rolling movement.
