AI Technical Summary
Existing methods for measuring the rotation angle of motor rotors suffer from problems such as frictional loss, complex installation, and poor long-term reliability. Traditional contact sensors are difficult to meet the requirements of high-performance control.
A non-contact rotor structure is designed by uniformly distributing arc-shaped recesses on the outer circumference of the rotor, using elliptical arcs to form the contour of the recesses, and combining them with a non-contact position sensor to detect signal changes in real time and calculate the rotor angle.
It achieves high-precision angle measurement with simple structure and easy processing, eliminates mechanical wear, improves system life and environmental adaptability, and enhances the versatility and measurement accuracy of the sensor.
