Optimization of Claw-Pole Alternators Using 3D Magnetic Field Calculation

  • G. Henneberger

Claw-pole alternators are used as automobile generators. The increasing amount of electronic components and small drives in cars help to make vehicles safer and more comfortable. So the alternator has to deliver more current, but at the same time its total volume must not change. Parallel the average speed of the combustion engine decreases because of increasing traffic density. So the alternator has to be improved at lower speeds especially.
