Phase conductor short circuit in star-connected motor?

ByMuecke64

Hello, I understand that in a star connection, there is no phase-to-phase short circuit at the bridge due to the phase shift and the fact that the voltages are always 0. But what would happen if I placed the bridge on the motor terminal board not at terminals U2, V2, W2, but at the top…

Power supply defective for bath electroplating?

There are several Eselsbrücken, for example for the Ohms Law:

In the Swiss canton

comes first the road

and then the city

Alternatively, you do not need formulas (or you can simply shake them out of the sleeve) if you have understood the units.

If you understand that

or

then the formula can be derived from it or simply the values can be used and calculated.

understand the physics behind it. You don’t forget an equation that you’ve derived yourself.

Many formulas can be gathered from the “logic”. Zb. s=v*t, If you are unsure, you can also compare the units, e.g. s=v*t so [km]=[km/h]*[h] the hour is shortened and km remains.

Classics from E-technology: U=R*I; you can remember this, through the canton “URI” in Switzerland…

Generally forming an “Eselsbrücke”, through an image, a place etc. – then it works significantly better than stupid memorization.

Over and over again, you’ll need to perform tasks. In the Abi, I did it so that I wrote up all the ones I had to do, and then wrote off the sheet so often until I was able to memorize it all.
