Also, a modulator is used, which slows down communication between the incoming voltage and frequency signals and the need for the motor to respond to this changing signal. Although the motor is mechanically simple, the drive is electri-cally complex. Evolution of direct torque control

3-Phase Induction Motors - UNLV
www.egr.unlv.edu• The basic idea of an electric motor is to generate two magnetic fields: rotor magnetic field and stator magnetic field and make the stator field rotating. The rotor will constantly be turning to align its magnetic field with that of the stator field. • The 3-phase set of currents, each of equal magnitude and with a phase
