| Abstract |
The magnitude of output torque in a BLDC Motor depends on torque angle so that the exact initial position of rotor is essentially required for good starting. This paper presents a novel starting control method for smooth starting in a position-sensorless controlled BLDC motor drive for reciprocating compressor of refrigerator. The proposed method starts a BLDC motor using information on the initial position of rotor, determined from current response characteristics, and shows robust starting capability to starting load variations. The effectiveness of the proposed method is verified through experimental results. |
