A Study on High Thermal Conductive Insulation for Claw Teeth Motors

Study on Downsizing Techniques for Conventional Motor with Solids Insulation System

“…Furthermore, as can be seen in Table , the errors in the estimated variability of the temperature reduction effect (S/N ratio) and in the temperature rise sensitivity relative to the confirmed values under superior heat dissipation conditions are approximately 19% and 30%, respectively. The confirmed threshold of reproducibility in the Taguchi method should be considered in general to be less than 30% , and thus good reproducibility is confirmed. Thus we chose a high heat dissipation structure for the SISM.…”

“…In this investigation, both the changes in the size due to the use of the heat dissipation element and the effect of temperature reduction in the heat dissipation element must be taken into consideration. We therefore performed an optimization study of the heat dissipation structure and the selection of a heat dissipation element using the Taguchi method in order to identify a configuration that allows maximal downsizing and provides a good temperature reduction effect . Below, the representative control parameters of the Taguchi method are explained.…”

“…High‐performance insulating resins with better characteristics than conventional products have been developed due to active research and development in recent years. For instance, a high thermal conductivity resin that have 10 times the thermal conductivity performance of past products while maintaining good insulation characteristics, and very strong and durable insulating resins using superior fillers and flexible materials, have been developed. This active development has included an attention to solid insulating resins with superior insulation performance to satisfy the demand for small and lightweight equipment.…”

Enlargement of Claw Pole Motor Using SMC Cores Divided in the Circumferential Direction

“…These fields have various required motor specifications and there is a need to develop dedicated application‐oriented motors for each sector . Based on these trends, attention has been focused on soft magnetic composite (SMC) claw pole motors , which are good candidates for miniaturization and flat design, and their performance has been studied by the development of design methods and trial fabrication . A new type of motor whose material and construction differ from past concepts, called the clawtooth® motor, has been created.…”
