Title: The Innovative Contributions of Raymond H. Hannula
Introduction
Raymond H. Hannula is a notable inventor based in Delafield, Wisconsin, who has made significant contributions to the field of electrical engineering. With a total of 10 patents to his name, Hannula has developed innovative solutions that enhance the functionality and efficiency of electrical devices.
Latest Patents
Among his latest patents is the "Electromagnetic operator for an electrical contactor and method for controlling same." This invention features an electromagnetic operator that includes first and second coils wound coaxially. An armature partially surrounds the coils, channeling flux during energization. The armature is designed as a bent plate secured to a ferromagnetic support. A control circuit applies energizing signals to the coils during operation, with both coils energized initially. One coil is subsequently de-energized automatically, while a timing circuit removes current from the second coil after a variable time period, which may depend on the configuration of the timing circuit and the energizing signal.
Another significant patent is the "Electric contactor housing," which presents a unitary housing structure for an electrical switching device, such as a three-phase contactor. This housing includes internal partitions that separate the operator section from contact sections and isolate phase sections from one another. The partitions are contiguous with the side walls of the housing, inhibiting plasma flow within the cavities. The housing is constructed from a thermoplastic material molded as a single piece, with shields within the phase sections to protect against plasma and arcs.
