Winding apparatus for divided stator core

Abstract

In the winding splitting type stator, the invention can maximally enlarge the claw part in iron core split by pole unit to make the gap between claw parts smaller and to make continuous winding in each pole part at the condition of all iron cores being assembled together. On one side the winding equipment lets the stator iron core mounted on the driving shaft to transfer a pole via the driving shaft, on other side it makes copper wire pass through interval between claws to make continuous winding on pole. The part of stator iron core extending outward is located in the winding device, and all iron cores are assembled along circumferential direction.

Description

technical field [0001] The present invention relates to a winding device for winding a coil on an outer rotor type stator core constituted by a unit structure of a rotating electric machine. Background technique [0002] The prior art discloses a structure (refer to Japanese Patent Document 2001-402936), such as Figures 1 to 4 As shown, in the outer rotor type stator core of the rotating electrical machine, the core element 4 divided into the magnetic pole unit composed of the yoke part 1, the magnetic pole part 2 and the claw part 3 is mutually arranged in the circumferential direction through the yoke part 1. It can be assembled movably within a certain range, unlike the prior art, which is assembled by press-fitting, and each core element can be easily assembled at one time in a state of being arranged in a circle. [0003] Each core element 4 is provided with a downwardly protruding arm portion 5 at the upper stage on one side of the yoke portion 1 and an upwardly proje...

Problems solved by technology

[0009] The problem to be solved is that in the split stator core, the split stator core cannot ensure sufficient clearance for passing the coils between the claws of the individual core elements in the assembled state, and there is the following complicated operation The problem is that the coils are wound on each core element separately in advance, and the wiring of each coil end is performed after assembly.

[0010] Moreover, since the method of arranging the divided core elements in a linear form has the following problems, that is, to continuously wind the individual core elements, a special winding device must be used, and the handling of the individual core elements that are continuously wound is reduced. Poor, poor operability when assembling them into one body
