Title: Jun Tarui: Innovator in Motor Control Technologies

Introduction

Jun Tarui is a notable inventor based in Kariya, Japan, recognized for his contributions to motor control technologies. With a total of 16 patents to his name, Tarui has made significant advancements in the field, particularly in shift range control systems and encoder technology.

Latest Patents

One of Tarui's latest inventions is a shift range control apparatus. This apparatus is designed to control the driving of a motor within a shift range switching system. It features a drive controller that adjusts the motor's operation to fit an engaging member into a recess based on the current shift range. Additionally, a polarity determination device assesses the stator's polarity facing the rotor. The drive controller then facilitates the movement of the engaging member and implements cancel energization control to reduce the magnetic flux density of the stator according to its polarity.

Another significant patent is a controller for determining the abnormality of a pulse outputter. This controller utilizes an encoder that generates four-phase pulse signals corresponding to the rotor's rotation. It can conclusively identify abnormalities in the encoder by monitoring the pulse output against a set timing rule. This innovation enhances the encoder's noise-proof characteristics, preventing false abnormality determinations even in the presence of noise interference.
