A coil insertion method includes winding U-phase, V-phase, and W-phase coils; inserting the U-phase, V-phase, and W-phase coils into a transfer block, such that the U-phase, V-phase, and W-phase coils are held in a plurality of holding grooves of the transfer block so as to spirally overlap, the transfer block having a columnar shape, and the holding grooves being formed in radial fashion around the transfer block so as to open from a center part of the transfer block toward an outer periphery thereof; inserting the transfer block into an inner periphery of the stator core; and pushing a side part of the coils held in the holding grooves radially outward toward predetermined slots of the stator core so that the coils are inserted from the inner peripheral side of the stator core into the slots.

Coil insertion method and coil insertion device

The present invention provides a stator coiled in a spiral, capable of mechanically inserting a wound coil in the slot of a stator core. In a stator in which coils are overlapped in a spiral when viewed from the end surface of the stator core after each of one sides of a plurality of coils wound in advance is inserted in the slot of the stator core and each of the other sides of the plurality of coils is inserted in a different slot, by repeating the inserting operation twice or more, the loop of the coils overlapped in a spiral are piled in two layers or more in the radius direction of the stator core and the total coil sectional area inserted in the slots of the stator core is larger than a prescribed value based on the inside radius of the stator core.

Stator

Two embodiments of winding methods and apparatus for winding coils of a rotating electrical machine where the armature teeth are skewed. The winding mechanism and method operates so that the winding needle does not have to enter to the bottom of the slots between the pole teeth but the wire is wound around the pole teeth from one end thereof with an arrangement for causing the windings to progressively move down the pole teeth as the winding continues.

Method of winding skewed armature and device therefor

An automatic machine and method of winding of armatures having maximum coil density because the winding nozzle does not enter into the slots between the pole teeth and the wire is directed toward the core portion of the armature during winding to improve coil density.

Armature, method and apparatus thereof

Armature structures and methods that provide very dense coil windings and afford very rapid winding methods at a relatively low cost. In addition the likelihood of damaging the already wound wires by contact with the winding nozzle is substantially eliminated. This is achieved by moving the winding needle in varying distances and directions away from the pole teeth to induce varying degrees of slack in the wire during the winding and when the needle is not in the slot between the pole teeth.

Method of winding armature of revolving field electric machine and armature

An automatic machine and method of winding of armatures having maximum coil density because the winding nozzle does not enter into the slots between the pole teeth and the wire is restrained at at least one the ends of the core portion of the armature to facilitate winding.
