Title: Takahiro Iida: Innovator in Motor Drive Technology
Introduction
Takahiro Iida is a notable inventor based in Ora-gun, Japan. He has made significant contributions to the field of motor drive technology, holding a total of 2 patents. His innovative designs focus on enhancing motor performance and efficiency.
Latest Patents
Iida's latest patents include a motor drive circuit that provides a low-speed start function and a soft start function. This invention features a first pulse generation circuit that generates a first pulse signal, with a duty ratio that increases as the drive voltage corresponding to the target rotation speed of the motor increases. Additionally, a second pulse generation circuit generates a second pulse signal with a different duty ratio. The drive control circuit supplies a drive current to the motor coil at the second duty ratio to initiate rotation and then switches to the first duty ratio after a predetermined time. Another patent involves a motor drive circuit that includes a first amplifier circuit to amplify the difference between first and second position detection signals. This circuit outputs a first amplification signal, while a second amplifier circuit amplifies the same difference with a gain that is opposite in phase to the first signal. The drive circuit then amplifies the difference between these two signals to output a driving voltage for the motor.
