Abstract

See full text

A winding-start receiving groove in which a winding-start lead wire of a field coil is received is formed in an inner surface of a flange of an insulation bobbin. A holder is disposed on the flange and located on a radially outer side of the winding-start receiving groove. The holder is formed with a holder groove located on an extension line of the winding-start receiving groove and extending at an angle relative to a radial direction of the insulation bobbin. The winding-start lead wire of the field coil is received in the winding-start receiving groove and the holder groove and held by the holder. This makes it possible to obtain a rotor of a rotary electrical machine with a simplified configuration at low cost not only to improve winding workability but also to enhance electrical reliability and durability.
