Title: Hiroaki Watano: Innovator in Motor Control Technology
Introduction
Hiroaki Watano is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of motor control technology, particularly in the design of circuits for paper shredders. With a total of three patents to his name, Watano's work emphasizes energy efficiency and innovative motor control mechanisms.
Latest Patents
One of Watano's latest patents is a motor control circuit for paper shredders. This invention enables the control of power consumption and achieves energy savings by realizing a torque characteristic of low torque at high speed or high torque at low speed while maintaining a steady output level of the motor. The circuit is designed for a paper shredder that includes a driving motor for a rotary cutter, which has an inverted linear flow characteristic between rotation speed and torque. The control circuit consists of a detecting block for the motor's rotation speed, a voltage control block that restricts the motor's voltage output within a specific range according to the rotation speed, and a current and voltage detecting block that monitors the motor's current flow. If the motor's current exceeds a certain level, the operation of the motor is suspended or reversed by a delaying circuit, ensuring efficient performance during paper shredding.
