When the three-phase voltage is present and all conditions are normal, the NO contact on the phase monitor relay (typically pins 1-8 on a plug-in product) closes, allowing the motor starter or contactor to be operated as normal...
Three phase squirrel cage induction motors can also be used as generators For this to work the motor must either be connected to a grid supply or an arrangement of capacitors to provide excitation current For the motor to work as a generator instead of a motor the rotor must be spun faster than its stator's synchronous speed...
Steadfast in his promotion of three-phase development, Mikhail Dolivo-Dobrovolsky invented the cage-rotor induction motor in 1889 and the three-limb transformer in 1890 Furthermore, he claimed that Tesla's motor was not practical because of two-phase pulsations, which prompted him to persist in his three-phase work...
