The invention relates to a novel motor. An annular hollow ring is defined by more than one hollow electromagnetic coil (4). After the electromagnetic coils (4) are energized, an annular magnetic lineof force flow is formed in the annular hollow ring. More than one imitated magnetic monopole (5) is fixed to an annular bracket (3) in the hollow ring. The imitated magnetic monopoles (5) move the annular bracket (3) in the annular hollow ring in one direction by means of the characteristic that the imitated magnetic monopoles move in one direction of the magnetic line of force. Thus, there is nocurrent and magnetic field transformation in operation, so ultrahigh speed and power can be obtained. The theoretical linear velocity is the speed of light when the centrifugal force limit of the annular bracket (3) and the system frictional resistance are not taken into consideration. Because of the difference in structure from a conventional motor, the method provides, by way of examples, two alternative ways for energy output including mechanical output and electrical energy output. The novel motor of the invention can also use other ways to output energy.
