ABSTRACT:
A brushless alternator for a vehicle comprising a field coil holding device formed by mounting a field coil winding spool directly on a field core using a bonding agent thus eliminating the need for a metallic cylindrical spool holder which requires precise machining in order to engage with the field core for welding. With this arrangement, a simple and inexpensive field coil holding device eliminates former precise machining. In addition, a field coil can be wound around the field coil winding spool in advance, before bonding to the field core.
