Rotor Position Detection and Start-up Methods of a Sensorless BLDC Motor

摘要：

　　A novel method based on the winding inductance variation is proposed which can estimate the rotor position within a maximum error of plus or minus 7.5 in electrical degrees and start the BLDCM afterwards.This means uses voltage pulses generated in two-phase and three-phase conduction modes to identify the rotor position,and combines voltage vectors to deliver a proper torque.Experiments on a sample BLDCM prove the feasibility of this new method.
