摘要： An excitation device supplies a three-phase AC excitation current to a variable speed generator-motor, and controls the variable speed generator-motor based on a three-phase AC excitation current command value obtained by vector-synthesizing, based on a slip phase from an exciting phase detector, a torque direction excitation current command value from a power adjustment computing device, and a magnetic flux direction excitation current command value from a voltage adjustment computing device by an excitation current adjustment computing device.

摘要： There is provided a single-phase AC synchronized motor that does not need smooth of rectifier waves but stably performs shift from a starting operation to a synchronized operation. In the motor, based on detected signals of a position sensor, rectified current is reciprocally flowed to each direction of a single-phase coil which starts the motor. The motor includes a start-up operation circuit with a sensor starting period that increases a rotational speed until reaching to a first predetermined rotational speed; and a control device that controls operation of the motor as that shift to synchronized operation is performed when a rotational speed of a permanent magnetic rotor is reached to a second predetermined rotational speed nearby a synchronized rotational speed but not exceeding the synchronized rotational speed, and when the rise and fall of detected signals of the position sensor and the zero-cross point of AC current are approximately correspondent to each other.

摘要： A motor system includes an air core motor having a rotor with opposed permanent magnet poles defining therebetween a magnetic airgap and driving magnetic flux across the magnetic airgap. A stationary armature with air core windings is located within the magnetic airgap. The permanent magnet poles produce a magnetic flux density through the air core windings to produce a back emf in the windings comparable to the voltage of the line power when the rotation of the permanent magnet poles is synchronous with the line power. A electronic variable speed drive coupled by a switch to the air core windings ramps up the frequency of power to the air core windings for accelerating the rotor to near line synchronous speed. When the frequency of the back emf approaches the frequency of the line power, the switch decouples the electronic variable speed drive and couples the air core windings to the line power for synchronous operation.

摘要： A system for preventing objectionable large torque pulsations during the starting and synchronization of a line-start permanent magnet motor compares motor speed with motor synchronous speed and power source phase with the motor back-emf phasor. The motor starting armature is coupled to the power source and the PM armature is disconnected from the power source before motor speed has reached to within a predetermined margin of synchronous speed and before the back-emf phasor has dropped below a predetermined phase difference. After motor speed has approached synchronous speed to within the margin and the phase difference has dropped below the predetermined phase difference, connections are reversed so that the starting armature is disconnected from the power source and the PM armature is coupled to the power source.
