<p class="p__0">In normal motor operation, the stator flux rotation is much faster than the rotor rotation. This triggers the stator flux to cause rotor currents, which create a rotor flux with magnetic polarity opposite to stator. In this method, the rotor is dragged along behind stator flux, with the currents in the rotor induced at the slip frequency.</p>
<br>
<p class="p__1">The stator flux still causes currents in the rotor, however considering that the opposing rotor flux is now cutting the stator coils, an active current is produced in stator coils and the motor now operates as a generator, sending out power back to the electrical grid. Excitation [edit] Comparable circuit of induction generator An induction generator needs an externally-supplied armature current.</p>
<br>
<p class="p__2">A source of excitation existing for magnetizing flux (reactive power) for the stator is still required, to induce rotor current. This can be provided from the electrical grid or, once it begins producing power, from the generator itself. The producing mode for induction motors is made complex by the need to delight the rotor, which starts with only residual magnetization.</p>

<br>
<p class="p__3">For that reason, it is necessary to either snap the motor and connect it briefly to a live grid or to add capacitors charged at first by recurring magnetism and supplying the required reactive power throughout operation. ARC Systems Inc. is the operation of the induction motor in parallel with a synchronous motor functioning as a power element compensator.</p>

<br>
<p class="p__4">Then active energy is being offered to the grid. Another drawback of induction motor generator is that it consumes a considerable magnetizing existing I0 = (20-35)%. An induction generator can be started by charging the capacitors, with a DC source, while the generator is turning normally at or above generating speeds.</p>

<br>
<p class="p__5">An induction generator that has recently been running might also spontaneously produce voltage and current due to residual magnetism left in the core. Active power [edit] Active power provided to the line is proportional to slip above the concurrent speed. Complete ranked power of the generator is reached at very small slip values (motor dependent, normally 3%).</p>

<br>
<p class="p__6">When the driving speed is increased to 1860 rpm (case in point), complete output power is produced. If the prime mover is not able to produce sufficient power to fully drive the generator, speed will remain somewhere between 1800 and 1860 rpm range. Needed capacitance [edit] A capacitor bank should supply reactive power to the motor when utilized in stand-alone mode.</p>
