Methods for dynamo-electric machine insulation handling

Abstract

Methods and apparatus for insulating interior walls of lamination slots of dynamo-electric machine components are provided. The relative speeds and sequence of cutting, forming, and inserting a piece of insulation material into the slot of the lamination core of a dynamo-electric machine component may be determined by a central drive mechanism. The central driving mechanism may have a plurality of cams, rotating with a main shaft, to control the translations of cutting, forming and inserting members.

AI Technical Summary

Benefits of technology

"The present invention relates to methods and apparatus for cutting and shaping insulating material in a way that allows for precise placement in a predetermined slot of a lamination core. The invention includes a central drive mechanism that controls the movement of the cutting, forming, and inserting members, resulting in higher accuracy and reliability of the insulation handling operations. The central drive mechanism includes a rotatable shaft and several subsystems for transferring the shaft rotation into translations of the cutting, forming, and inserting members. The invention also includes an enclosure for the central drive mechanism to prevent contamination of the insulation and improve operator accessibility. The technical effects of the invention include improved accuracy and reliability of insulation handling operations, increased productivity, and simplified procedures such as lubrication, startup, and shutdown."

Problems solved by technology

However, such machines typically have a large number of moving mechanical parts and are generally difficult to lubricate and maintain.

Insulation material can become contaminated by lubricating procedures on some insulating handling machines.

Other machines have enclosed insulation handling mechanisms to minimize contamination of the insulation, but such enclosures generally impede lubrication of internal mechanisms.

In addition, closed configurations are cumbersome for setting up machine insulation operations or troubleshooting mechanical problems.

These difficulties increase the likelihood of breakdown and lead to unsatisfactory levels of accuracy, reliability, and productivity.
