Latest Patents

Nobuo Takechi’s latest patents focus on three-phase armature winding configurations. The first patent describes a three-phase four-pole armature winding of the double-layer lap type. In this design, Takechi dispersively arranges three first pole windings of respective phases in first divided regions of the slot area, which is segmented into three equal parts. This innovative approach allows for the efficient coil insertion process, where all coils for the first through fourth pole windings of each phase can be inserted simultaneously using an automatic coil inserter. Additionally, the structural arrangement ensures that coil impedance is equalized across all phases due to the consistent radial position of the pole windings relative to the iron core.

The second patent presents a three-phase armature winding configuration of the concentrically wound double-layer type. In this design, the coil ends of the three-phase first pole windings are strategically placed on the outermost circumference, while subsequent pole windings are distributed on inner circumferences in a systematic arrangement. This design not only enhances the overall efficiency of the winding process but also promotes optimal performance in electrical machines by reducing adverse effects associated with uneven coil distributions.
