摘要：This invention provides a dynamo-electric machine that makes it possible to minimize windage losses and excels in terms of rotor strength. Also, the number of poles in said dynamo-electric machine is reduced. A plurality of connecting-hole pairs each comprising two connecting holes 34 that connect to the outer circumference of the rotor
13b are formed in said rotor 13b in the direction of rotation thereof. The area between the two connecting holes 34 constituting each connecting-hole pair forms a center bridge 32 that joins a core section 31 of the rotor 13b to an umbrella-shaped section 33 on the outside in the radial direction of the rotor 13b, and the side of each connecting hole facing away from that center bridge 32 connects to the outer circumference of the rotor. Between the connecting-hole pairs, the rotor 13b has a plurality of radial protrusions 36 and 36a that protrude in the radial direction of the rotor 13b from the axis of rotation
14a. Each of said radial protrusions 36 and 36a has side protrusions 361 and 362 that protrude towards the umbrella-shaped sections 33 that are adjacent in the direction of rotation of the rotor 13b. Some of said side protrusions 362 cover the umbrella-shaped sections 33 or parts thereof from the outside of the rotor.
