Study on Rotor Position Detection Error in Sensorless BLDC Motor Drives

In this paper, the main reason causing rotor position detection error in sensorless BLDC motor drives that the band pass filters are employed to get the zero-crossings of back-emf is presented. The effects on commutation that result from the rotor position detection error are investigated, and the simulation results are given. The correction method is suggested, and the experimental results are provided
