Latest Patents
One of Hisashi Kitahara's latest inventions is a magnetostriction type torque sensor. This innovative device features first and second sets of grooves that define elongate projections. These projections are subject to compression and elongation when the shaft experiences torque. The design includes two yoked coils, excited with alternating current, positioned close to the projections. As the projections compress and elongate, the magnetic flux flowing along them changes, which in turn affects the inductance of the coils. This configuration forms part of a bridge circuit that is sensitive to changes in inductance, allowing for accurate torque measurement. Another similar patent also focuses on a torque sensor for automotive transmissions, utilizing the same principles to enhance performance and reliability.
