Title: Ryo Maeda: Innovator in Rotation Angle Detection Technology
Introduction
Ryo Maeda is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of rotation angle detection technology, holding a total of 15 patents. His innovative work has been instrumental in advancing the capabilities of direct current motors.
Latest Patents
One of Maeda's latest patents is a rotation angle detection device and method. This device includes a current meter that measures the current flowing in a direct current motor. It features a filter that extracts a ripple component from the current, a ripple detector that identifies the ripple from the filtered signal, and a rotation angle detector that determines the rotation angle of the motor based on the number of detected ripples. The rotation angle detector also measures an observation period based on consecutive ripples and calculates an estimation period between them. It ensures that the observation period remains within a normal range, allowing for the correction of the number of ripples when necessary.
Another notable patent involves a rotation angle detecting method that measures the current flowing through a motor. This method obtains the rotation angle based on the measured current value. It takes into account the inertial rotation of the motor, utilizing the rotational angular velocity immediately before a specified time point and the time periods between key events during the motor's operation.
