Document Type and Number:
Japanese Patent JP6946065
Kind Code:
B2
Abstract:
Provided is a brushed motor in which noise in a high rotational speed range is effectively decreased. A bar-shaped flat attachment 28 of synthetic resin is inserted along an axial line L into an opening of a slot 16 formed in a core 14 of a rotor 7, and fixed with respect to the core 14 and/or windings 17 using adhesive agent. The flat attachment 28 has side surfaces 28b and an inner peripheral surface 28c. The side surfaces 28b are engaged from an inner peripheral side with inclined surfaces 15a of teeth 15 adjacent to each other across the opening of the slot 16. The inner peripheral surface 28c of the flat attachment 28 has two ridges 28d protruding therefrom which are abutted against the windings 17. The flat attachment 28 closes the opening of the slot 16 and shapes an outer peripheral surface 14a of the core 14 into a flat cross sectional shape suitable for suppression of wind noise.
