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.

A method of joining terminals by soldering is provided which allows control of increasing gas supply even in soldering performed in a gas atmosphere within a gas chamber. Utilizing a springback phenomenon occurring at a flat portion of a terminal, a solder joint of the terminal is immersed in molten solder. Then, laser soldering is performed using a gas chamber made of a material which transmits a laser beam at least in part.

After respective one ends of lead wires are fixed to a printed circuit board, the lead wires are bent, the printed circuit board is brought into a case and the other ends of the lead wires are bonded to terminals of the case. Since the lead wires are processed before the substrate is brought into the case, this eliminates the necessity to perform formation of the bent portions of the lead wires and fixing of the lead wires to the substrate in a narrow space of the case and allows simplification of bonding operation. Thus provided is a lead wire bonding method for bonding lead wires with bent portions to the substrate, which simplifies a bonding operation.

An automotive alternator rectifier including a terminal connection portion configured by connecting a terminal leading out of first unidirectional conducting element bodies disposed on a surface of a first heat sink so as to be spaced apart or a terminal leading out of second unidirectional conducting element bodies disposed on a surface of a second heat sink so as to be spaced apart with a circuit board terminal is disposed between a rotor and a circuit board. For this reason, temperature increases in the first unidirectional conducting element bodies and the second unidirectional conducting element bodies can be suppressed and workability when connecting the terminal connection portion is improved.
