Abstract
An object of the present invention is to provide a small, high-power rotating electrical machine by suitably forming a distributed winding coil such that two stator magnetic poles each formed of in-phase coil turns are arranged within an electric angle of 360 degrees formed by magnetic poles of the rotor. The present invention provides a method for manufacturing a stator, the method including a first step of placing a distributed winding coilcomposed of a wire wound around a reel, as a whole, inside a stator core, and a second step of moving an insertion bladeso as to spread the distributed winding coilin the radial direction of the stator core, thus inserting the distributed winding coilinto a stator core slot
