A vehicular starting and charging rotary electric machine includes a rotor, a stator, brackets, a brush, and a rotation detection sensor. The rotor has a field winding. The stator has a stator winding. The brackets supports the rotor and the stator. One end of the brush is brought into contact with the rotor to supply field current to the field winding of the rotor. The rotation detecting sensor is arranged coaxially with a rotating shaft of the rotor, for detecting a state of the rotor and functioning as a motor or a generator. The magnetic pole position detecting sensor is integrally fixed to the bracket.

A method for varnish application to a dynamoelectric stator is disclosed. The method includes a varnish treatment process and application by preheating the stator; adjusting a viscosity of the varnish; dripping the varnish onto a coil end of the stator from radially outside the stator while rotating the preheated stator around a central axis; and hardening the varnish dripped onto the coil end by heating the stator. The varnish viscosity is adjusted so that said varnish dripped onto said coil end passes through the coil end from radially outside to radially inside, and the varnish is dripped onto said coil end along a direction which is perpendicular to the central axis of the collective coils.
