Magnetic field in a wound rotor induction motor
- Mauro Andriollo
Move the slider "STATOR ELECTRIC ANGLE" and see how the stator and rotor magnetic fields and rotate at the same speed. The rotor lags behind them (you can change the lagging by the slider SLIP, the higher the slip the slower the rotor. The rotor stops for . Take notice that rotor current frequency is times the stator current one (see sinusoids at the left). For the rotor rotates backwards with respect to the magnetic field (dissipative braking operation), for the rotor rotates faster than magnetic field ().
