Abstract
This electric motor includes first permanent magnets secured integrally to an outer periphery side rotor and second permanent magnets secured integrally to an inner periphery side rotor. The first permanent magnets and the second permanent magnets are arranged so as to offset the relative torque produced between the outer periphery side rotor and the inner periphery side rotor based on the magnetic flux of the inner peripheral permanent magnets and the outer peripheral permanent magnets.
