Conversion is based on the use of two capacitor banks, one, delta connected and one star connected. Both banks may be permanently connected to the phase terminals of the motor or they can be connected separately during start-up and loading. Two relays with interconnected coils are between one...

The working characteristics are analyzed and compared in order to establish the advantages...
conductors. This connection is called astar, or wye, connection. Alternatively, since the three winding voltages also sum to zero at every instant, the three windings can be connected in series—a′ tob,b′ toc, andc′ toa—to form adelta connection. The output can then betransmittedusing ...
In such cases, the stator is star connected in the lower speed range and switched to a delta connection above a threshold speed. In this study, a new switching scheme is proposed wherein the stator coils are always connected in a star, while the stator is connected to different voltages ...

SUBSTANCE: synchronous generator has stator carrying three-phase winding and shaft-mounted rotor with field winding. Phase circuits of stator winding are provided with selector switch affording their series-parallel connection and changing over from star to delta connection and vice versa. Rotor field ...
Usually AC generators are star connected, but in this case the generator is delta connected. The stator configuration has some similarity with the rotor winding of a DC motor. The basic principle of operation in such a set-up remains the same, and is applied for a very large number of ...
