Abstract

A method for manufacturing a neutral ring includes connecting a cut-off neutral ring to an arc-shaped connection element. The method also includes filling an insulator between the cut-off neutral ring and a connection element. The neutral ring shunts the rotor coil in three phases.

Claims (6)

1. A method for manufacturing a neutral ring for use in a rotating electrical machine, the method comprising steps of:

cutting off the neutral ring in part, wherein the rotating electrical machine includes a rotor coil, a rotor core, a bind that receives centrifugal force of the rotor coil, and a lead-out wire that extends from the rotor coil and of which one end is connected to the rotor coil and the other end is connected to the neutral ring;

connecting the cut-off neutral ring to an arc-shaped connection element;

forming a plurality of members in the arc-shape to overlap with one another; and

filling an insulator between the cut-off neutral ring and the connection element, wherein

the neutral ring shunts the rotor coil in three phases.
