Title: Hideo Sawaoka: Innovator in Motor Control Technology
Introduction
Hideo Sawaoka is a prominent inventor based in Kariya, Japan. He has made significant contributions to the field of motor control technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and reliability of motor operations through innovative control methods.
Latest Patents
Sawaoka's latest patents include a motor control device and a motor control method. This invention features a rotational speed command output unit that receives and outputs a command value for motor rotational speed. A PWM duty calculator calculates the PWM duty based on the command value and the actual rotational speed of the motor. Additionally, a maximum speed estimator determines the maximum rotational speed achievable under PWM control, ensuring that the command value does not exceed this limit. This innovation effectively suppresses abrupt changes in motor speed due to voltage fluctuations.
Another notable patent is a pulse width modulation communication system. In this system, a sensor unit transmits reference pulses with duty cycles of 100% and 0% before sending a transmission signal containing compressed data. An input capture circuit measures the duty time and PWM cycle of the transmission signal, while a signal processing circuit produces a duty cycle correction factor. This allows for accurate data reception from pressure and temperature sensors.
