In an abduction-type motor having a divided core 5(a-l) formed by dividing a stator core into plural blocks and a motor stator having such a structure as the divided core may be reassembled, the motor has a coil winding frame 6 continuously formed a continuous unit of coupling parts, a part of which is flexible and made of insulation material, embedded into the individual divided cores, and a coil 7 arranged and wound by supporting the divided core so that the teeth top parts of the divided core may be directed inside and located on a circle, in which its coil winding structure has the number of coil stages at the teeth top part (external peripheral part) of the divided core larger than the number of the coil stages at the internal peripheral part, and the diameter of the teeth top part of the divided core after assembly is identical to the diameter of the teeth top part while coil winding work, and the length of the crossover line 7s between the coil windings is made enough to be equivalent to a single slot or more, not excessive or not insufficient.
An abduction-type motor having a divided core formed by dividing a stator core into plural blocks and a motor stator having such a structure as said divided core may be reassembled, wherein said motor has a coil arranged and wound by supporting said divided core so that teeth top parts of said divided core may be directed inside and located on a circle, and lead lines for a start of a coil winding and an end of a coil winding are arranged at said teeth top parts.
An assembly method of a stator of an abduction-type motor having a divided core formed by dividing a stator core into plural blocks with its teeth top parts arranged in a direction to outside and having such a structure as be reassembled with said divided cores, wherein said motor stator is assembled by means that a coil winding frame formed as a series of units, each coupled at coupling parts made of insulation material and embedded into said individual divided core, a part of which can be flexibly bended, is embedded into said individual divided core, coupling parts of said coil winding frame is made deformed and arranged while coil winding work so that teeth top parts of said divided core may be arranged on a hypothetical circle and directed to its inside, coil winding work is applied continuously to said divided cores, and that coupling parts of said coil winding frame is deformed after coil winding work so that teeth parts of said divided core may be directed to outside.
