Current distribution in a Claw-pole Alternator
The device is a claw-pole automobile alternator with a three-phase output winding on the stator. A field coil around the rotor core is used to induce flux in the output windings as the rotor spins.
The full model is shown here, however for simulation purposes, two symmetry planes are matched with an even periodic boundary condition. The MagNet 3D analysis model consists of a 60 degree section comprising one rotor pole pitch pair.Open Report (Model 0070)
