Systems and methods for refurbishment of motor generators

Abstract

Systems and methods are provided to refurbish a commutator in-place without disassembly of a motor generator. The disclosed system may include a drive/brake system for controlling the rotation of the commutator during the refurbishment process, and a multi-axis Computer Numerical Control (CNC) motion and machining platform for controlling processing and refurbishment devices that traverse the commutator surface. Such devices may include an undercutting device to remove dielectric material from between commutator bars, a stoning device to obtain a polished surface finish for the commutator, and a chamfering device to remove burrs at the edges of the commutator grooves left by the stoning process. Alignment and inspection devices may be utilized along with mobile panels and cameras. The subsystems and components of the disclosed system may comprise a modular implementation designed for transportation and assembly in space-constrained environments.
