Method for assembling large-diameter electric motor

A method for assembling a large-diameter electric motor, comprising

• a preparing step:
• providing two or more stator segments for forming a stator and two or more rotor support segments for forming a rotor support;
• a splicing step:
• splicing the two or more stator segments and the two or more rotor support segments in a predetermined manner to form the stator and the rotor support that are coaxially assembled, respectively, and maintaining a predetermined gap between the stator and the rotor support in a radial direction;
• and
• an assembling step:
• inserting a plurality of magnetic pole modules into the predetermined gap, and assembling the plurality of magnetic pole modules to a mounting surface of the rotor support;
• wherein the assembling step comprises
• pre-arranging a plurality of pressing strips on the mounting surface of the rotor support, so that each of mounting rails is formed between each two adjacent pressing strips;
• placing the plurality of magnetic pole modules on the mounting rails respectively;
• and
• pressing the pressing strips on the adjacent magnetic pole modules and fixing the pressing strips on the mounting surface;
• the placing the plurality of magnetic pole modules on the mounting rails respectively comprises
• placing the plurality of the magnetic pole modules on first mounting rails and second mounting rails in sequence, respectively, and the mounting rails comprising a plurality of first mounting rails and a plurality of second mounting rails respectively distributed at 180° in the circumferential direction of the rotor support.
