The main advantage is that hybrid field motors only use half of the amount of rare-earth magnet, compared to a synchronous motor, that you can see in today's hybrid or electric vehicles.

Thane Heins succeeded to recover this back-EMF and, instead of letting it cause resistance, he transformed it into useful power. This claim has brought him opposition for many years from the scientific community, because it seems to violate Lenz's law.
