Parrallel motor cables in trefoil, phase formation. 2

See also PRYSMIAN’S WIRE AND CABLE ENGINEERING GUIDE page 21

Hello, thank you for the answer.

I've seen the ABC ABC ABC recommendations in many places, but i suspect it is the general recommendation because it is easy, and it will almost always be a sufficient formation.
Although the ABC ABC ABC formation should be sufficient, I'm wondering if the solution with clockwise rotated phase formation is better.
If it is better i see no reason to not create a more balanced drive supply.



Thanks in advance

Hi we have this in our National Standard (equivalent to IEC I believe). Since your stated goal is maximum reduction of current imbalance you should follow table D1.

The ABC ABC etc configuration is only for when your cable spacing is such that the influence of the magnetic fields no longer overlaps (significantly) and therefore there is no interaction.
