The application is a compressor with an old resistor starter where the resistors burnt out. They tried shorting out the slipprings and starting via a soft starter. The motor stalled and they blew up the soft starter! A rotor reactor looks an elegant solution as the impedence falls with the rotor...
Can anyone recommend the best way to calculate a starting reactor? Can it be as simple as X = Rotor volts/root 3.Rotor amps for full load torque(assuming negligable resistance)
