Dictionary of Electrical Engineering

Commonly used terms in the Electrical industry.

eddy current
a circulating current in magnetic materials that is produced as a result of time-varying flux passing through a metallic magnetic material.
eddy current brake
a braking device in which energy is dissipated as heat by generating eddy currents.
eddy current drive
a magnetic drive coupled by eddy currents induced in an electrically conducting member by a rotating permanent magnet, resulting in a torque that is linearly proportional to the slip speed.
eddy current loss
the energy wasted in sustaining undesirable eddy currents in an electrical conductor.
