THEORY, CONSTRUCTION, AND OPERATION
geosci.uchicago.edunent magnets in synchronous machines are restricted to those with ratings much lower than large turbine-driven generators, which is the subject of this book. Turbine-driven generators (for short: turbogenerators) take advantage of the fact that magnetic fields can be created by the flow of electric currents in conductors.
Operation of Induction Generators.
www.egr.msu.edusynchronous speed no power is delivered. The reason why there is not power is because the difference between the synchronous speed and the operating speed is zero. But if a motor is driven at a higher speed than the synchronous speed, the torque will be negative and start acting as a generator rather than a motor.

web.mit.edugenerators. Of particular concern to utility engineers is how much current a generator can deliver during a fault on their system. Inverters generally produce less than 20% of the fault current as a synchronous generator of the same nameplate capacity. This is a very significant difference.
