Excitation winding

from Wikipedia, the free encyclopedia

When excitation winding which are coil ( field winding consisting of wire - windings ) in an electric machine referred to the magnetic field for the energy conversion ( main draw / air gap field generating), when executed by a electric current ( excitation current flows through). In the case of DC machines, one also speaks of the main pole winding . The part of the machine provided for this is called the pathogen.

The name is derived from the term magnetic excitation , the historical name of the magnetic field strength.

Machines with permanent magnets do not need an excitation winding. These, usually machines of low to medium power, are also referred to as permanent excited.
