Title: The Innovations of Robert E. Campbell
Introduction
Robert E. Campbell is a notable inventor based in Anderson, IN (US), recognized for his contributions to technology and engineering. With a total of 4 patents to his name, Campbell has made significant advancements in the field of alternating current generators and engine sensors.
Latest Patents
One of Campbell's latest patents is for a stator assembly for an alternating current generator. This innovative stator core is a one-piece molded part made from iron powder, which has a particle size ranging from about 10 to 250 microns. The powder is bound together by a thermoplastic material that insulates the particles from each other. Additionally, the particles may be coated with phosphorus, which is then overcoated with the thermoplastic material. The design includes a three-phase output stator winding carried by the core, with conductor portions located in core slots.
Another significant patent is for an engine detonation sensor with a double shielded case. This detonation sensor is designed for mounting on a vehicle engine component and features a cylindrical outer case with an open end. Inside, an inner cylindrical case is positioned coaxially within the outer case, held slightly axially separated by a magnetostrictive rod and a magnet. The edges of the outer case are crimped over a washer that abuts the closed end of the inner case, exerting axial stress on the magnetostrictive rod. Both cases are made from magnetic material to shield the coil from external electromagnetic signals.
