Control Induction Induction motor Motor Phase Three phase

AI Thread Summary

In open loop voltage/frequency (v/f) control of three-phase induction motors, determining the frequency and amplitude of the triangular carrier wave for sinusoidal PWM is crucial for effective motor operation. The frequency should be chosen based on the desired switching frequency and the motor's response characteristics. The amplitude of the triangular wave typically matches the maximum voltage output of the inverter. Proper selection impacts the efficiency and performance of the motor control system. Further insights or resources on this topic would be beneficial for those working on similar projects.

I am doing project on open loop v/f control of three phase induction motor. How to decide the frequency and amplitude of triangular wave(carrier wave) for sinusoidal PWM ?

I have wondered this in the past and of course do not know the answer. If you find out elsewhere, let us know please.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
