Abstract

The invention discloses a rotor structure with a split type pressing plate, and relates to the field of motor accessories, in particular to the rotor structure with the split type pressing plate; according to the technical scheme, the rotor structure comprises a rotor magnet yoke, wherein a plurality of magnetic pole modules which are arranged in a split mode are uniformly distributed on the outercircumference of the rotor magnet yoke, and pressing plates used for tightly pressing the magnetic pole modules are arranged at the two ends of the axial direction of the rotor magnet yoke; the rotorstructure is characterized in that the pressing plate on at least one end of the rotor magnet yoke is arranged as a split type pressing plate, and the split type pressing plate is composed of a plurality of deformation fan-shaped baffles with concentric modes and equal diameters, and the baffles are arranged corresponding to the magnetic pole modules; a ventilation gap is formed between every twoadjacent baffles, and at least two bolt holes are formed in each baffle; bolts for fixing the baffles and the rotor magnet yoke are inserted into the bolt holes; and mounting holes corresponding to the bolt holes are formed in the end plane of the rotor magnet yoke. The rotor structure is mainly used for assembling a rotor of a motor, in particular to a rotor assembly of a semi-direct drive permanent magnet wind driven generator.

Description

technical field [0001] The invention relates to the field of motor accessories, in particular to a rotor structure with split pressure plates. Background technique [0002] The rotor structure of the semi-direct drive permanent magnet wind turbine usually consists of a rotor yoke, magnetic pole modules distributed uniformly in the circumferential direction outside the rotor yoke, and pressure plates located at both ends of the rotor yoke. The existing pressure plates all adopt an integrated structure. During assembly, the rotor pressure plate on one side is installed first, then the magnetic pole modules are installed separately, and finally the rotor pressure plate on the other side is installed. This structure and installation method, on the one hand, after the installation of each magnetic pole module, if it is not pressed in time, it is easy for the magnetic steel to jump out or loosen, which has certain potential safety hazards, and it is easy to cause rework and reduce...
