Title:
COIL SUBSTRATE FOR MOTOR, AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2024/084624
Kind Code:
A1
Abstract:
Provided are a coil substrate for a motor with which a motor having high torque and high performance can be obtained, and a motor formed by using the coil substrate for a motor. A coil substrate for a motor according to the present embodiment has a flexible substrate having a first surface and a second surface on the side opposite the first surface, and a plurality of coils formed by wiring provided to the first surface and the second surface, the coil substrate for a motor being formed into a cylindrical shape by being wound in a circumferential direction with a first longitudinal-direction end of the flexible substrate as a starting point, centered on an axis extending in an orthogonal direction that is orthogonal to the longitudinal direction. The occupancy ratio of the coil in a cross-section of the coil substrate for a motor is 50-99%.
