Title:
MOTOR COIL SUBSTRATE, AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2024/084625
Kind Code:
A1
Abstract:
Provided are: a motor coil substrate whereby a high-torque, high-performance motor can be obtained; and a motor formed by using the motor coil substrate. The motor coil substrate according to an embodiment of the present invention comprises: a flexible substrate having a first surface and a second surface on the reverse side from the first surface; and a plurality of coils formed by wiring provided on the first surface and the second surface. Said motor coil substrate is formed into a cylindrical shape by being wound in the circumferential direction about an axis extending in an orthogonal direction that is orthogonal to the longitudinal direction of the flexible substrate, starting from a first end of the flexible substrate in the longitudinal direction. The percentage of the wiring that accounts for the total weight of the motor coil is 80.0% to 99.9%.
