Abstract
A motor includes two magnetically coupled, coaxially-nested Halbach cylinder rotors, one of which passes through a toroidal series of at least two stator coils while the other is attached to an axle or other means of transferring mechanical power. An embodiment is described comprising an additional third Halbach cylinder rotor in which a circumferential arrangement of permanent magnets is mounted rotatably and proximally outside the stator coils, coaxial with the stator coils. Adjacent stator coils are configured so as to produce opposing magnetic fields upon energizing of the motor. Alternating the current to the stator coils induces movement in the rotor. Commutation can occur brushlessly, or the motor can be configured to function without commutation by varying the frequency of the alternating current, and can be configured to operate by either DC or AC current. Alternatively, the rotor may be driven to generate an electric current in the stator.
