Title: Innovations by Shoutarou Hashimoto: Pioneering Motor Control Technology
Introduction
Shoutarou Hashimoto is an accomplished inventor located in Yamanashi, Japan, with an impressive portfolio of 18 patents. His innovative work primarily focuses on motor control technologies, showcasing his expertise and impact on the field.
Latest Patents
Among Hashimoto's recent patents, two notable contributions stand out. The first is a **motor control apparatus equipped with a boosting unit**. This invention comprises a converter that transforms AC voltage from an AC power supply into DC voltage. It then channels this DC voltage to a DC side before passing it through an inverter that generates AC voltage for motor operation. A unique boosting unit steps up the DC voltage fed to the inverter according to deviations between the speed command for the motor and the actual speed information it receives.
The second significant patent is a **motor controller**. This innovative controller contains a rotation speed estimating unit that projects the motor's rotation speed based on current and primary frequency information. It features a proximity switch that outputs signals indicating the position of the motor's rotating body. Moreover, it includes a rotation speed calculating unit that uses these signals to compute the motor's speed, alongside a speed command compensating unit aimed at minimizing the error between the commanded and calculated speeds. Finally, a speed control system integrates these components to ensure precise motor control.
