Apparatus for Detecting the Angle of Rotation and Load Torque of DC Motor DC Motor Controller and Electric Motor-driven Power Steering System

摘要

assignment;A method of detecting a rotation angle of a DC motor that accurately detects a load torque without complicating the apparatus.;Solution;The DC motor 13 is driven for a drive time set so that the angular acceleration of the DC motor 13 is substantially constant at a predetermined drive torque and the drive time of the DC motor 13 and the generation voltage of the DC motor 13 after the drive And estimates the rotation angle of the DC motor 13 while the DC motor 13 is being driven.
