The revolving Element of alternators is often the armature or even the magnetic area. The revolving armature type has the armature wound to the rotor, where the winding moves by way of a stationary magnetic area. The revolving armature variety is rarely utilized.[18] The revolving area kind has magnetic subject over the rotor to rotate through a stationary armature winding. The gain is usually that then the rotor circuit carries significantly less ability compared to the armature circuit, building the slip ring connections lesser and fewer pricey; only two contacts are wanted for that immediate-present-day rotor, Whilst often a rotor winding has a few phases and many sections which might each demand a slip-ring connection.
