<p> Provided is an electric motor that, by rotating efficiently, allows power consumption and radiated heat to be minimized with minimal reduction in output. An electric motor (10) is provided with a rotor (20), a stator (30), and a controller (40). The rotor (20) has permanent magnets disposed along the circumferential direction. The stator (30) has coil portions (33) disposed facing the permanent magnets, each of the coil portions (33) having therein a magnetic body as a core that becomes magnetized and attracted to the permanent magnet when the permanent magnet approaches wound wires (33a) that generate a magnetic pole repulsing the permanent magnet. The control device (40) does not pass electricity through the coil portions (33) for attracting the permanent magnet by a core (33b), but passes electricity through the coil portion (33) for repulsing the permanent magnet by the wound wire (33a) in the direction of rotation of the rotor (20). The control device (40) can cause the rotor (20) to rotate efficiently because the rotor (20) rotates by the permanent magnet being repulsed by the coil portion (33) and the permanent magnet is attracted to the core (33b) even without the flow of electricity through the coil portion (33).</p> |
