Title:
COIL SUBSTRATE, COIL SUBSTRATE FOR MOTOR, AND MOTOR
Document Type and Number:
Japanese Patent JP2023042670
Kind Code:
A
Abstract:
To provide a coil substrate with which a motor with stable performance can be obtained, a coil substrate for a motor that is formed by using the coil substrate, and a motor that is formed by using the coil substrate for a motor.SOLUTION: A coil substrate of an embodiment has a flexible substrate that has a first surface and a second surface on the opposite side of the first surface; and a coil that is formed by coil-shaped wiring provided on the first surface and coil-shaped wiring provided on the second surface. The coil substrate can be formed in a cylindrical shape by being wound in a circumferential direction centered on a shaft extending in an orthogonal direction orthogonal to the longitudinal direction, with a reference side at one end in the longitudinal direction of the flexible substrate as a starting point. The wiring has an orthogonal part extending along the orthogonal direction. The orthogonal part includes a first orthogonal part on the first surface and a second orthogonal part on the second surface. At least one of the first orthogonal part and the second orthogonal part is formed in a wave shape.SELECTED DRAWING: Figure 2
