Latest Patents

Olson's latest patents include a "Method for fabricating a split-loop armature coil for a motor." This invention features a unique coil configuration that comprises eight individual parallel conductors, which are electrically insulated from each other. The design allows for a rectangular cross-section and splits the conductors into two groups of four, creating an air gap at the loop portion of the coil. This split-loop configuration enhances cooling surface area, reduces hot spot temperatures, and increases the current capability of the machine. Additionally, it mitigates the risk of shorted turns between conductors, thereby improving the machine's reliability.

Another significant patent is the "Insulated armature coil for dynamoelectric machine." This invention involves a multiple turn coil designed to fit into a rotor slot of a dynamoelectric machine. It consists of a bundle of individually insulated parallel bars of electroconductive material, surrounded by a pre-formed tube made of non-compressible, non-thermoplastic dielectric material. This design allows for flexibility and accommodates the thermal expansion and contraction of the insulated conductors, while a cross-shaped member enhances turn-to-turn insulation.
