Filed: 2007-02-07
Abstract: <P>PROBLEM TO BE SOLVED: To improve rigidity of one end part 3a of a field coil 3 (edgewise coil) to which a brush lead wire 5a is connected and to improve vibration resistance.  <P>SOLUTION: The brush lead wire 5a is connected to one coil end 3a pulled out from the field coil 3. A rib-like projection 7 projected to one wide face in a board thickness direction is arranged in one coil end 3a. Since section modulus with respect to a load on a vertical direction of the wide face of one coil end 3a becomes large, rigidity of the coil end 3a improves. Consequently, large displacement of the brush lead wire 5a connected to one coil end 3a of the field coil 3 due to engine vibration can be suppressed. Thus, vibration resistance of the coil end 3a can be improved, and disconnection of the brush lead wire 5a can be prevented.  <P>COPYRIGHT: (C)2008,JPO&INPIT
