WebOct 20, 2024 · induction generator working principle induction generator types 1. Above synchronous speed, operating an induction generator becomes impractical. It’s important to keep the generator’s rpm below the breakaway torque. When the speed exceeds the breakaway torque, the real power quickly drops to a negligible level. An induction generator produces electrical power when its rotor is turned faster than the synchronous speed. For a four-pole motor (two pairs of poles on stator) powered by a 60 Hz source, the synchronous speed is 1800 rotations per minute (rpm) and 1500 RPM powered at 50Hz. The motor always turns slightly slower than the synchronous speed. The difference between synchronous and operati…
