Title:

COIL ROTATION TYPE ELECTROMAGNETIC CLUTCH

Document Type and Number:

WIPO Patent Application WO/2010/024443

Kind Code:

A1

Abstract:

Brushes (20, 21), which slide on slip rings (23, 24) having power feeding terminals (51, 53) to be electrically connected with a power feed side, are provided with extensions (32, 36) extending in the radial direction of a feed core (3). The extensions (32, 36) are so formed as to be bent in a direction away from a coil bobbin (12), and third bent portions (32c, 36c) positioned at the ends are electrically connected with terminal portions (10d, 10d) of coil terminals. A mounting recess (3a) housing a power feeding unit (5) of the feed core (3) has an outer diameter (R1) made smaller than the inner diameter (R2) of the coil bobbin (12). As a result, the mounting recess (3a) can be so positioned in the feed core (3) as to be separated in the direction shown by an arrow (A) from a coil-wound portion (14) of the coil bobbin (12) by a distance (H), whereby the size of a coil rotation type electromagnetic clutch (1) can be reduced in the directions shown by arrows (A-B).
