Method For Determining Rotor Position Of Electric Motor, Elevator And Electrical Converter Unit
Patent No. EP3706306 (titled "Method For Determining Rotor Position Of Electric Motor, Elevator And Electrical Converter Unit") was filed by Kone on Mar 8, 2019. The application was issued on Jul 16, 2025.
Patent Summary
A method for determining the rotor position of an electric motor, particularly in elevator applications, that minimizes rotor movement during position determination. The method applies a controlled force to maintain the rotor in place while supplying an excitation signal, and then analyzes the resulting response signal to determine the rotor position. The controlled force is applied in a direction opposing rotor movement, and the excitation signal is designed to magnetically saturate the rotor core material.
