Title:
COIL PRODUCTION METHOD, COIL OF MOTOR, AND STATOR OF MOTOR
Document Type and Number:
WIPO Patent Application WO/2008/087994
Kind Code:
A1
Abstract:
A coil production method capable of improving the space factor of a straight angle
conductor with respect to the slot of a stator core, a coil of a motor, and a stator
of a motor. The coil production method in which one surface of a rectangular-section
straight angle conductor (15) is brought into contact with a guided shaft (83),
and edgewise bending is performed along the curved surface of the guided shaft
(83), wherein a deformation mechanism (62) for reducing the plate thickness
of a plate thickness changing portion (15a) equivalent to one of the corners of
a coil over the entire width of the straight angle conductor (15) is provided,
the deformation mechanism (62) is used to deform the plate thickness changing
portion (15a), and the plate thickness changing portion (15a) of the straight
angle conductor (15) is edgewise-bent to form a coil.
