Title: Masato Sakai: Innovator in Electric Power Steering Systems
Introduction
Masato Sakai is a notable inventor based in Katsuta, Japan. He has made significant contributions to the field of electric power steering systems, holding a total of 2 patents. His innovative designs have enhanced vehicle steering technology, making it more efficient and responsive.
Latest Patents
Sakai's latest patents include an electric power steering control system and an electric power steering apparatus. The electric power steering control system features an electric motor that produces assisting torque for the vehicle's steering system through a reduction gear. It incorporates a steering torque sensor, a controller that adjusts motor input based on sensor output, a battery for power supply, and a voltage step-up circuit to drive the motor at a higher voltage than the battery. The controller effectively manages the motor's operation to enhance steering performance.
The electric power steering apparatus consists of a steering shaft, a detector for monitoring the power steering operation, and an electric motor that generates assisting force for steering. It also includes a reduction gear with an input shaft driven by the motor and an output shaft connected to the steering shaft. The planetary gear mechanism within the reduction gear reduces the rotational speed of the input shaft and transmits this reduced speed to the output shaft. An electromagnetic clutch is integrated into the gear case, allowing for the switching between locked and unlocked positions based on the detector's output.
