The revolving Section of alternators might be the armature or the magnetic field. The revolving armature kind has the armature wound on the rotor, wherever the winding moves through a stationary magnetic subject. The revolving armature sort is hardly ever applied.[eighteen] The revolving industry style has magnetic discipline over the rotor to rotate via a stationary armature winding. The gain is then the rotor circuit carries much less ability when compared to the armature circuit, making the slip ring connections scaled-down and fewer pricey; only two contacts are desired for your direct-latest rotor, While generally a rotor winding has 3 phases and various sections which would Every demand a slip-ring connection.
