Document Type and Number:
Japanese Patent JP6503590
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve embedded holding of a permanent magnet in a rotor.SOLUTION: A dynamo-electric machine includes: a rotor 5 in which a permanent magnet 3 is rotatably arranged to a circumferential direction; a first stator 7a to which a winding 6a is provided; a second stator 7b to which a winding 6b is provided; and a case 8, and includes a control part 18 that comprises: an electric power supply device 9 that rotates and drives the rotor by supplying an electric power to one winding; and an electric power collection device 10 that fetches out an induction current generated in the other winding by the rotation of the rotor to be driven. The rotor has a cylindrical body in which both ends of a cylindrical part are freely edges, and the first stator or the second stator include magnet gap forming means of forming a radial direction gap by floating the rotor between the first stator or the second stator and the rotor with a magnetism force and magnet position setting means of properly setting an axial direction relative position. The permanent magnet 3 forming each pole of a rotation magnetic field is embedded with an interval of a plurality of small magnets 3p into the rotor.SELECTED DRAWING: Figure 1
