Title: Isamu Yasunobu: Innovator in Motor Control Technology
Introduction
Isamu Yasunobu is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of motor control technology, holding a total of 2 patents. His work has been instrumental in advancing the efficiency and functionality of motor control systems.
Latest Patents
One of Yasunobu's latest patents is a motor controller that features a circuit arrangement for controlling the starting current of a motor. In this innovative motor control apparatus, a motor is driven by rectifying alternating current (a.c.) voltage and smoothing the rectified voltage using a capacitor. The voltage across the capacitor is monitored to determine if it falls below a reference voltage, utilizing a first comparator. If the voltage is indeed below the reference, an output voltage is generated. This output voltage is then employed to adjust another reference voltage of a second comparator, which detects whether the current to the motor or the motor drive circuit exceeds the reference level. When the current surpasses the reference, the comparator produces a low-level output, prompting a control circuit to manage the drive circuit and reduce the current to the motor.
