Claims

[Scope of utility model registration request]

In a wound rotary electric machine in which power is supplied to an external device through a slip ring and a brush to which a lead wire from a rotor coil drawn out to the end of the rotating shaft is connected, on the outer periphery of the end of the rotating shaft, A brush holder made of an insulating material to which a plurality of axially protruding brushes each having different rotation radii is attached is fixed, and a lead wire from the rotor coil is connected to each of the brushes through the brush holder. A wound rotary electric machine characterized in that a slip ring formed of a round rod shape and a ring shape is disposed on a stationary side facing each of the brushes connected to each other and projecting in the axial direction.
