A 400 V, 50 Hz, 6-pole, 940 rpm, star connected induction motor has the following parameters: stator and rotor resistances are 1.25 each, and stator and rotor leakage reactance are 2 each (magnetising reactance can be neglected). The motor is controlled by simultaneous stator voltage and frequency variation. Voltage boost is not used and the motor is controlled using V/f = constant law. The motor is supplied from a three-phase voltage source inverter d) A variable-speed electric drive can operate in two distinct speed control regions. Name these regions, explain the principal difference between them and specify which quantity is kept constant in each of the two [4 marks]
