Iron Core Hysteresis-Based Position Sensorless Control of PM Brushless DC Motors
A sensorless position detection technique based on iron core B-H hysteresis for PM brushless DC motors at standstill and low-speed is presented.A signal acquisition setup and a control method are provided.Experiments show that this technique has a good starting and low-speed control performance for both non-salient and salient motors.With this technique,a closed-loop starting can be achieved and the start-up time can be shortened.This technique has a wide adaptability and good application prospects.
