MANUFACTURING METHOD OF STATOR FOR MOTOR

PROBLEM TO BE SOLVED: To make it possible to quickly and easily wind coils over a specified number of divided stator cores, by superposing a plurality of frame-like air-core coils on a straight line with a specified gap in-between, and inserting the plurality of the divided stator cores into these gaps in sequence. SOLUTION: A specified number of frame-like air-core coils 18 having a space 16 therein are formed. The plurality of the air-core coils 18 are superposed on one another with a specified gap 34 in-between, and are arranged on a straight line. Feet 22 of divided T-shaped stator cores 14 are inserted into gaps 34 between the plurality of the air-core coils 18 in sequence. Recesses 24 and projections 26 formed on heads 20 of the respective stator cores 14 are engaged with each other to form an annular stator 10a. The annular stator 10a is placed in an annular housing 12 to form a stator 10. Thereby, it is possible to easily wind the air-core coils 18 over a specified number of the stator cores 14.
