What do shading coils do

A not-for-profit organization, IEEE is the world's largest technical professional organization dedicated to advancing technology for the benefit of humanity.

Use of this web site signifies your agreement to the terms and conditions. Electromechanical contactors have the drawback of the mechanical movement of some of their parts and the wear related with it.

This movement causes the contacts to impact during closure, producing a bouncing of the contacts and consequently the estimated life of the contacts is dramatically reduced. Join Our Free Trial Now! Learn More About shading coil.

Homophones, Homographs, and Homonyms The same, but different. The main alternating magnetic flux induces currents in the Frager coil. So, these induced currents create an auxiliary magnetic flux. This auxiliary flux is out of phase from the main flux.

The property of property allows the armature sealed-in when the main flux falls to zero e. Without this shading ring, the armature would tend to open each time the main flux goes through zero and create noise, heat and mechanical damages on the magnet faces e.
