Doubly-fed induction generator (DFIG) technology has been challenged recently by more stringent network requirements, the fault ride-through requirement in particular, and adaptations have been made to respond to these issues.
(See How real For a four pole machine, 60 x 50 / 2 = 1500 rpm so the same size motor at 5.5kW, 400v but 4 poles will have a nominal speed of 1500rpm but will run near 1455 rpm. An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. ABB is a pioneering technology leader that works closely with utility, industry, transportation and infrastructure customers to write the Induction generators operate by mechanically turning their rotors faster than synchronous speed. The impedance is the passive parameter of the AC voltage, and for DC it is resistance. The turbine-control characteristics equivalent to the generators are X 1 =60(60 - f), X 2 = 120(70 - f), X 3 = 140(80 - f) Where, f denotes the system frequency in Hz, and X 1, X 2, X 3 are the power outputs of the turbines in MW.

Power-to-weight ratio is a measurement of actual performance of any engine or power source. Doubly-fed induction generator (DFIG) technology has been challenged recently by more stringent network requirements, the fault ride-through requirement in particular, and adaptations have been made to respond to these issues. Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources to enable the comparison of one unit or design to another. This is an AC generator. Since motors and generators are similar in construction, it should be possible to use a generator as a motor, and conversely, to use a motor as a generator.

An induction generator or asynchronous generator is a type of alternating current (AC) electrical generator that uses the principles of induction motors to produce electric power.
Standard. The history of linear electric motors can be traced back at least as far as the 1840s, to the work of Charles Wheatstone at King's College London, but Wheatstone's model was too inefficient to be practical.
