Transient Analysis of Induction Motor: Usefulness of analysis of transient operating conditions of a drive, e.g. starting, braking, load changing, speed changing, etc. is already explained. A rigorous analysis of…
Dynamic Braking of Induction Motor(or Rheostatic Braking): (a) AC Dynamic Braking - AC Dynamic Braking of Induction Motor is obtained when the motor is run on a single phase supply…
Braking of Induction Motor Drive: Following methods are employed for Braking of Induction Motor Drive: Regenerative braking Plugging or reverse voltage braking Dynamic (or rheostatic) braking further categorised as: ac…
Starting of Induction Motor Drives: Starting of Induction Motor Drives arrangement is chosen based on the load requirements and nature of supply (weak or stiff). It may be required to…
Harmonic Equivalent Circuit of Induction Motor: When fed from an inverter or cycloconverter, the motor terminal voltage is non-sinusoidal but it has half-wave symmetry. A non-sinusoidal waveform can be resolved…
Three Phase Induction Motors: Three Phase Induction Motors are of two types: squirrel-case and wound-rotor. In squirrel-cage, the rotor consists of longitudinal conductor-bars shorted by circular connectors at the two…
Field Oriented Control of Three Phase Induction Motor: The stator current of an induction motor has the functions of producing the required air gap flux (magnetisation) as well as developing…
Wound Rotor Induction Motor with Subsynchronous Converter Cascade in the Rotor Circuit: The following points favour the application of a slip ring motor having static slip energy recovery scheme in the…
