Abstract
The utility model discloses a heat dissipation hole type light-duty rotor body of a wind driven generator. The heat dissipation hole type light-duty rotor body comprises a rotor shaft and a rotor sheet body arranged on the rotor shaft, wherein permanent magnets are arranged on the outer circumferential surface of the rotor sheet body; and cylindrical holes are formed in the rotor sheet body in the axial direction of the rotor shaft. The utility model has the advantages that heat transfer can be accelerated, and heat is dissipated through the metal outer surfaces of a front end cover, a rear end cover and a stator casing, so that the temperature of the rotor body is lowered, and meanwhile, the temperature of gas in both a front cavity and a rear cavity is lowered; and the rotor body not only brings convenience for the permanent magnets to better play the performance in low temperature, but also ensures that a winding and other insulating materials can not quickly get aged, so as to meet the requirements for long service life and high performance. Moreover, the weight of the rotor body is reduced.
