Low-energy-consumption and high-efficiency circulating electric motor

A low-energy-consumption and high-efficiency circulating electric motor, which comprises:

• a pedestal having a rotating-shaft;
• a magnetic driving device having a frame, a fan, and a DC electromagnet;
• wherein the fan is set on the rotating-shaft and is rotatable along the rotating-shaft;
• wherein at least one blade of the fan is set with at least one permanent magnet, and the DC electromagnet is set on the frame and corresponded to a path of the permanent magnet rotating with the fan;
• an intermittent conductive device having a circular cylinder-body set on the rotating-shaft, wherein the outer diameter surface of the circular cylinder-body is set with a continuous circumferential conductive portion, and a plurality of axial conductive portions are lined in interval and connected to the circumferential conductive portion;
• a second gear set on the rotating-shaft;
• a DC generator having a first gear;
• wherein the first gear meshes with the second gear;
• and
• a storage battery electrically connected with a control unit, the DC generator, the circumferential conductive portion, and the DC electromagnet;
• wherein the storage battery electrically contacts with the circumferential conductive portion through a first conductive element, and the DC electromagnet contacts with the outer diameter surface of the circular cylinder-body through a second conductive element;
• wherein the circular cylinder-body and the second gear are rotated via the rotating-shaft when the fan rotates;
• and then the DC generator is driven to rotate through the first gear to generate power to charge the storage battery;
• at the same time, the second conductive element orderly contacts and does not contact the axial conductive portions, wherein the DC electromagnet, the intermittent conductive device, and the storage battery are controlled by the control unit to intermittently form a current loop;
• further, the DC electromagnet intermittently generates a magnetic force which interacts with the permanent magnet to rotate the fan;
• wherein the permanent magnet is in a state which interrupts the current loop within an angular range of the rotation passing the DC electromagnet;
• and after the angular range is exceeded, the circuit loop is formed again to constitute cyclic charging and discharging to drive the fan to continuously rotate.
