Abstract

Some embodiments of the disclosed invention provide a toroidal DC motor that reduces Back EMF and, therefore, minimizes the degradation of source potential. In addition, embodiments of the disclosed invention provide a motor that provides constant torque at constant current irrespective of the speed of the rotor. Likewise, some embodiments of the disclosed inventions provide output horsepower that increases with the rotational speed of the rotor.
