Sullivan alternator
All Sullivan Pancake Alternators use rare earth magnets for high power density and high efficiency. They have no brushes or slip rings to wear, and with few or no moving parts, they have very low noise and excellent reliability.

These units produce an AC voltage that varies in amplitude and frequency with RPM. Within their operational range, the faster they spin, the more power they can supply.

In most cases these alternators mount directly to an engine or drive shaft. No transmission is needed. The alternator hub is machined to accommodate the bolt pattern of the drive hub, or crankshaft interface.

It is also possible to drive the alternator with a coupling or to mount pancake alternators on a secondary shaft and drive them with a belt or gears. While less efficient than direct driving, this is an approach that can be used when space constraints prevent mounting directly to the drive hub.
