Title:
ELECTRIC CONTACT MECHANISM FOR SMALL MOTOR
Document Type and Number:
WIPO Patent Application WO/2005/096474
Kind Code:
A1
Abstract:
[PROBLEMS] To provide an electric contact mechanism for a small motor in which durability of electric contacts can be improved by reducing mechanical abrasion and electrical abrasion. [MEANS FOR SOLVING PROBLEMS] In an electric contact mechanism for a small motor especially for one having a relatively high driving voltage or power consumption, carbonaceous materials are employed as the contact material. The carbonaceous materials are bundled together into a brush shape having lengths ranging from several hundreds μm to several mm. Consequently, mechanical sliding abrasion can be reduced, and furthermore generation of arc can be suppressed, thereby reducing electrical abrasion (electrical corrosion).
