PROBLEM TO BE SOLVED: To provide a magnetic force rotation device which solves problems of efficiency improvement and downsizing of the device.SOLUTION: A magnetic force rotation device 10 includes a stator 12 and a rotor 14. A plurality of electromagnets 17 are fixed to a frame 23 of the stator 12. A core 30 of the electromagnet 17 has a trunk part 28 extending in an axial direction of the shaft 37 and two legs 29 extending from the trunk part 28 to the shaft 37. Each leg 29 is formed into a rectangular parallelepiped shape which is long in the axial direction of the shaft 37 and short in a circumferential direction. The trunk part 28 is formed into a rectangular parallelepiped shape which is short in a radial direction of the shaft 37 and long in the circumferential direction. A cross sectional area of the trunk part 28 is the same as a cross section area of each leg 29.SELECTED DRAWING: Figure 5 |
