20080238232 | Motor, rotor structure and magnetic machine - A motor includes a stator having first and second armatures to form a rotating magnetic field, an inner rotor having first and second permanent magnets, and an outer rotor arranged between the stator and the inner rotor. The outer rotor has a rotor body which supports first and second induction magnetic poles such that they are embedded therein. A phase of the first induction magnetic pole is matched with a phase of the second induction magnetic pole. The first and second induction magnetic poles are assembled to the rotor body such that they are inserted into linear slits formed in the rotor body in the axis direction. Because the first and second induction magnetic poles are aligned in the axis direction, the outer rotor has a simple structure and an increased strength, and also support and assembling of the first and second induction magnetic poles in the outer rotor are facilitated. | 10-02-2008 |
20080296997 | Rotor for rotating electrical machine - A rotor body for an electric motor is comprised of connecting outer peripheral portions of first and second flange members made of electrically conductive material to the opposite ends of a plurality of connection members made of electrically conductive material of weak magnetic material arranged at predetermined distances therebetween in the circumferential direction with bolts and by supporting induction magnetic poles made of soft magnetic material between the connection members which are adjacent in the circumferential direction. Coupling portions of the first and second flange members and the connection member are electrically insulated by insulation coating so that an eddy current flowing in a closed circuit comprised of the first flange member, the connection member, the second flange member and the other connection member can be reduced and heat dissipation and energy loss accompanied by the eddy current can be minimized at the time of an operation. | 12-04-2008 |
