PROBLEM TO BE SOLVED: To provide a dynamo-electric machine capable of rotating while increasing the speed of a cooling blade for the rotating shaft, while suppressing power consumption.SOLUTION: A dynamo-electric machine 10 has magnet bodies 17 formed annularly by arranging M pole pairs of magnets 17b in the circumferential direction, K modulators 16a fixed to a rotating shaft 18, and magnet bodies 14m consisting of N magnetic members (segments and magnets). One or more blades 14a are fixed directly or indirectly to the magnet bodies 14m, and the magnet bodies 17, modulators 16a, and magnet bodies 14m are arranged, in this order, in the radial direction. With such an arrangement, the blades 14a provided in the magnet bodies 14m rotate by a reactance torque acting between the magnet bodies 17 or modulators 16a. Since power is not required separately, power consumption can be suppressed. When setting the number of the magnet bodies 17, modulators 16a and magnet bodies 14m, the blades 14a can be rotated while increasing the speed for the rotating shaft 18.SELECTED DRAWING: Figure 1 |
