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…
Function Generation and Linearisation: An important aspect of the closed loop control system is the use of Function Generation and Linearisation, e.g. in the control of induction motors there exists…
Field Oriented Control of Induction Motor: In the slip controlled drives using VSI or CSI discussed in the foregoing secÂtions, the stator voltage or stator current is controlled using slip…
Speed Control of Variable Frequency Induction Motor: Speed Control of Variable Frequency Induction Motor of a squirrel cage induction motor can be controlled very effectively by varying the stator frequency.…
What are Passive Filters?: Passive filters are mainly networks using inductors, capacitors and resistors. The classical theory employed was based on the image parameter theory which in turn was based…
FFT Spectrum Analyzer Using a Waveform Processing Software(SS-36): FFT Spectrum Analyzer - The Waveform Processing Software (SS-36) enables one to analyze waveforms very easily. The waveform is captured on a Digital…
Oscilloscope Operating Precautions: In addition to the general safety precautions, the following specific precautions should be observed when operating any type of oscilloscope. Most of the Oscilloscope Operating Precautions also…
Induction Motor Speed Control Methods: The only way to control the speed of a synchronous motor is to control the input frequency and voltage such as to keep V/f constant.…
