Latest Patents

Hirofumi Nakano’s most recent inventions include a stepping motor that features rust inhibiting and eddy current minimizing characteristics. This innovative stepping motor design employs stator yokes with comb-tooth-shaped magnetic poles that are arranged coaxially with a rotor made from a permanently magnetized permanent magnet. The external circumference of the stator yokes is fitted with an excitation coil that, along with the stator yokes, is surrounded by a frame yoke. Each yoke is constructed from an Fe–Cr alloy that possesses a specific ferrite single-phase structure, effectively suppressing the development of eddy currents in alternating-current magnetic fields.

Another notable patent from Nakano involves the design and method of producing a stator yoke that enhances the magnetic characteristics and provides rust-proofing effects. This stator yoke utilizes a Fe-Cr type alloy, which improves magnetic properties. However, it is crucial to perform press working with careful attention to sustain these magnetic characteristics, as they tend to decline during the shaping process. By applying annealing techniques, Nakano overcomes this challenge, ultimately enabling recovery of magnetic characteristics while ensuring the rust-proofing effect remains intact.
