MOTOR
Document Type and Number:
Japanese Patent JP2023095221
Kind Code:
A
Abstract:
To reduce manufacturing costs of a motor by reducing the size of an electronic substrate while suppressing damage to the electronic substrate due to static electricity.SOLUTION: A motor including a substrate 1 comprises: a shaft 4 which is a stepped structure with a rod-like projection 41 formed at one end in the axial direction and smaller in diameter than the outer diameter of the other portion except for the one end and concentric; a first circuit pattern 13 which is provided on the substrate 1 and to which a specific electronic component 14 is connected; and a second circuit pattern 11 which is formed on the substrate 1 at a position where the shortest distance from the shaft 4 which is charged with static electricity is shorter than those of both the first circuit pattern 13 and the electronic component 14, and discharges the static electricity from the projection 41.SELECTED DRAWING: Figure 3
