WELDED COPPER POLE SYNCHRONOUS MACHINES

CHALLENGE

The copper conductors of the coil should have as little electrical resistance as possible. In the corners, the longitudinal ladders must be connected to the transverse ladders. This connection should have the strength and the electrical properties of the base material.  The internal dimension of the coil should ensure an optimum gap to the core.

SOLUTION

The longitudinal ladders and transverse conductors are accurately welded, cleanly grounded and assembled in a Lehre in the TIG process.  The welding process was tested and released according to ISO15614-6.  The execution of over 250 connections is carried out by our certified welders.
