Which Poles Do I Connect for Short Circuiting in a Wound Rotor Motor?

    Rotor Wound
AI Thread Summary
The discussion revolves around connecting the correct poles for short-circuiting a wound rotor motor with six output poles (a, b, c, a0, b0, c0) in order to run it via a frequency inverter. The motor, an old asynchronous type from VEB MEZ VSTEIN, is used in a testing facility to simulate wind speeds for a large fan. The user seeks advice on which poles to connect, as they have experience with simpler motors that have only three poles. The goal is to transition from the old connection scheme to a more modern control method using a frequency converter. Clarification on the pole connections is essential for successful operation.

Hello,
I have problem with an old asynchronous motor with wound rotor it is VEB MEZ VSTEIN.I am intending to run the motor via frequency inverter by connecting it to the stator windings. I need to short circuit the rotor, but there are 6 poles coming out (a,b,c and a0,b0,c0) from the wound rotor collector and I don’t know which one to connect to which. Can you help me with advice?
Thank you

It is quite huge motor it is in a testing facility. I t is rotating a big fan in a tunnel and its purpose is to simulate a wind with a particular speed.But the guys want to get rid of this old scheme connection and want to control it via frequency converter. Actually i did this but with a normal asynchronous motor with wound rotor with only 3 poles on the rotor which i had to get short circuit them to each other, but this monster has 6 poles as you can see on the scheme (maybe 3 for the beginning and 3 for the end of the rotor winds).

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...
