[0002] The traditional permanent magnet wind turbine assembly process is mainly to wrap the rotor magnetic steel with magnetic isolation material, and then assemble it with the permanent magnet wind turbine stator. This purpose is mainly to prevent the magnetic steel from being absorbed by the stator core during the assembly process, causing damage The impact damage of the magnetic steel, but the positioning of this method is not good, the assembly efficiency is low, and the magnetic steel wrapping effect directly determines whether the magnetic steel can be protected during the assembly process, and the efficiency of this method is low in the mass production process , the assembly quality is also difficult to guarantee

Embodiment Construction
[0026] The present invention will be further described below in conjunction with specific embodiment:
[0027] A method for assembling and positioning based on the rotor drive shaft structure of a permanent magnet wind power generator, characterized in that it comprises the following steps:
[0028] A. Install the rotor transmission shaft 4 on the platform 8
[0029] Lift the rotor transmission shaft 4 to the middle of the platform 8, and fix the rotor transmission shaft 4 on the platform 8 through T-shaped bolts 9; the working surface of the platform 8 should be flat and clean, so the platform should be cleaned before installing each component 8. Keep the platform 8 clean;
[0030] B. Place square box 7
[0031] Place the square box 7 for supporting the permanent magnet generator stator frame 6 on the described platform 8; according to the outer diameter size of the permanent magnet generator stator frame 6, the equal height square box 7 is placed in a suitable position, so...
