Title: Paul S. Johrde: Innovator in Dynamoelectric Machine Technology

Introduction

Paul S. Johrde is a notable inventor based in Franklin, PA (US). He has made significant contributions to the field of dynamoelectric machines, holding a total of 3 patents. His innovative work focuses on enhancing the efficiency and reliability of electrical components.

Latest Patents

One of his latest patents is a casting assembly for stator coils and method. This invention encapsulates the terminal portion of a winding end turn conductor, which projects from the core member of a dynamoelectric machine, in an epoxy potting compound. The casting assembly comprises a detachable conformable pad, a plastic sleeve mold, and a portable vise. The conformable pad provides a temporary barrier to axial flow of the epoxy compound during casting. The plastic sleeve is positioned around the terminal portion in a spaced relationship, creating a barrier to radial flow. Clamping means, such as a portable vise, are used to establish a compressive union at the interface of the conformable pad and the conductor, preventing leakage. Additionally, spring members hold the sleeve in place during the casting process. A sealing compound is applied to prevent leakage, and once the epoxy has cured, the assembly can be reused for other conductors.
