Principle of Adjustable Speed Control Stator field Rotor Rotor speed Rotational speed of stator field Stator Usually, a constant speed generatormotor is excited by the DC excitation system fixed on the rotor. The rotational speed of the rotor field equals the rotor speed. Rotor field Frequency of excitation system Adjustable generator-motor However, an adjustable speed generator-motor is excited by the AC excitation system fixed on the rotor. Therefore, the rotational speed of the rotor field equals the sum of the rotor speed and the frequency of the AC excitation. nS=nR n2 This document contains information proprietary to Mitsubishi Electric Corporation.
