See also. Full rated power of the generator is reached at very small slip values (motor dependent, typically 3%).
As the speed of the motor increases the counter torque reaches a max value of torque (breakdown torque) that it can operate until before the operating conditions become unstable. An induction generator produces electrical power when its rotor is turned faster than the synchronous speed. An induction machine requires externally supplied armature current; it cannot start on its own as a generator. Electric Machines. For a machine to run as an asynchronous generator, capacitor bank must supply minimum 4567 / 3 phases = 1523 VAR per phase. Because the rotor field always lags behind the stator field, the induction machine always "consumes" reactive power, regardless of whether it is operating as a generator or a motor. If the load also absorbs reactive power, capacitor bank must be increased in size to compensate. Therefore, claims of making a unit generates more power than its rated should get a closer examination. Minimum capacitance per phase:. This causes the stator flux to induce rotor currents, which create a rotor flux with magnetic polarity opposite to stator.
