Brushless two-pole generator main field leads connection to rectifier assembly
TLDR
In this paper, the leads are arranged so that they extend through a generally axially extending hole in the rotor with their free ends being connected in a parallel splice configuration which extends radially outward from the hole.Abstract:
An electric generator and a method of securing a connection between flexible electrical leads from a rectifier and a main field winding in a rotor of the generator wherein the leads are arranged so that they extend through a generally axially extending hole in the rotor with their free ends being connected in a parallel splice configuration which extends radially outward from the hole with the connected free ends being secured with respect to the rotor so as to remain in the radially outward extending position during rotation of the rotor. The rectifier is located at one end of the magnetic core and field winding of the main generator with the rectifier leads extending through a hole in the magnetic core and a field winding insulator to the opposite end of the magnetic core and field winding for connection with the field winding leads. Rotational forces will not pull the lead wire connections apart and the connections are readily accessible for repair.read more
