Abstract: A field winding type synchronous machine has a stator having a stator core to which a stator coil is wound, and a rotor that rotates while facing a peripheral surface of the stator with an electromagnetic gap therebetween. The rotor includes a rotor core having a plurality of main pole portions and interpole portions, main pole windings wound around the main pole portions, interpole windings wound around the interpole portions, and a full-wave rectifier circuit for energizing the field current to the main pole windings. The interpole windings produce the induced current by a magnetic flux generated by a time harmonic current superimposed on a fundamental wave of the stator coil. The electromagnetic gaps between the interpole portions and a circumferential surface of the stator are configured larger than electromagnetic between the main pole portions and the circumferential surface of the stator.

Abstract: A bistable relay and a bistable actuator are provided. The bistable actuator includes a magnetic latching mechanism and an electromagnet. The magnetic latching mechanism includes a rotation shaft, a pillar-shaped permanent magnet, a columnar hollow magnetic conductor and two shells, and operates between a first and second stable states. The columnar hollow magnetic conductor surrounds the pillar-shaped permanent magnet wrapping the rotation shaft, and maintains a gap with the pillar-shaped permanent magnet. The electromagnet is connected to the columnar hollow magnetic conductor for driving the pillar-shaped permanent magnet to rotate, so as to switch the magnetic latching mechanism to the stable state. During a process that the magnetic latching mechanism is switched to the stable state, the rotation shaft rotates synchronously along with the magnetic latching mechanism to drive an impact system to move relative to a contact system, so as to contact or disconnect the contact points.
