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.
