Quick Summary

A heteropolar machine, specifically an inductor alternator, is a type of synchronous generator where both the field and output windings are located on the stator. It generates voltage in output windings through flux pulsations caused by a toothed rotor. This design varies the magnetic reluctance of the air path as the rotor turns, creating these pulsations. Inductor alternators are useful for high-frequency generation and applications requiring high reliability due to their rotor having no electrical connections.1

A homopolar generator, on the other hand, produces direct current without reversals of potential or the need for commutation.2
