Abstract
A rotor pole crossover connection joint for use in a rotating electrical machine is disclosed. The connection joint integrally couples a bottom rotor coil strap to a rotor pole crossover connector with a single piece connector that reduces, distributes or otherwise tolerates stress concentrations in the connector. A corresponding method of forming a rotor pole crossover connection and a rotor assembly including a rotor pole crossover connection joint are also disclosed

A method of forming a rotor pole crossover connection joint in a rotating electrical machine comprising:
- providing a rotor pole crossover leg;
- providing a stack of coil straps including a bottom coil strap and a first coil strap stacked atop said bottom coil strap so as to extend beyond a termination of said bottom coil strap exposing a bottom surface of said first coil strap;
- providing a single piece connector that couples said termination of said bottom coil strap to said rotor pole crossover leg having:
- a body member;
- a coil-side connector arm having a coil end;
- a first shoulder that couples said body member to said coil-side connector arm;
- a crossover-side connector arm having a crossover end;
- and
- a second shoulder that couples said body member to said crossover-side connector arm so as to space said crossover-side connector arm away from said coil-side connector arm;
- connecting said coil-side connector arm coil end to said bottom coil strap termination so as to extend generally coplanar with said bottom coil strap such that an arm surface of said coil-side connector arm is positioned adjacent to said exposed bottom surface of said first coil strap;
- coupling said crossover-side connector arm to said second shoulder;
- and
- connecting said crossover-side connector arm crossover end to said crossover leg.
