The invention relates to a device for providing a motor that delivers a larger amount of produced energy than the amount required for the operation thereof, eliminating the need for a primary energy supply. The device consists of electromagnets produced with coils of incomplete turns arranged in a stator and permanent magnets arranged in a rotor. When an electric current is applied to the coils of incomplete turns, a force is generated in the magnets, causing the rotor to rotate and generate mechanical energy. The coils of incomplete turns are characterized in that, when the rotor rotates, they allow the magnets of the rotor to pass continuously through said coils.
