  • Patent number: 11824407
    Abstract: A method for manufacturing a distributed straight-angle armature winding according to the present invention comprises a step (a) of preparing a raw material in which at least a pair of intra-slot winding areas and an end winding area provided between the pair of intra-slot winding areas are continued, a step (b) of forming an inclined surface by processing a contact surface in contact with an inner surface of a slot of at least a stator of the circumferences of the pair of intra-slot winding areas, and a step (c) of bending a space between the end winding area and the intra-slot winding area.
    Type: Grant
    Filed: September 28, 2018

  • Patent number: 11581773
    Abstract: A flat-angled coil having a three-dimensional shape for maximizing a space factor according to the present invention comprises a unit coil comprising multiple layers which are provided to surround the peripheries of teeth of a core provided on an electric motor and laminated along the longitudinal direction of the teeth of the core so as to be integrally connected to each other continuously. The unit coil is formed such that at least a part of an adjacent portion thereof, which is adjacent to another unit coil provided in the same slot formed between the surrounded teeth of the core and the teeth of an adjacent core, is non-parallel with the side surfaces of the surrounded teeth of the core.

  • Patent number: 11404944
    Abstract: Disclosed is a method for manufacturing an MSO coil, comprising: a pressing step of forming a bent surface on a part of a unit coil layer, which has a ring shape such that both ends thereof face each other, thereby endowing both ends of the unit coil layer with a height difference; a fixing step of connecting and fixing a plurality of unit coil layers to each other, each unit coil layer having the bent surface formed thereon, such that the first end of both ends of a unit coil layer having the bent surface formed thereon contacts the second end of both ends of another unit coil layer having the bent surface formed thereon; and a bonding step of bonding connection parts defined by contact of the first and second ends of each of the plurality of unit coil layers that are connected and fixed to each other.
