This paper describes advanced brushless DC motor drive without position sensor for home appliances with compressor to reduce the pulsating currents and vibration. The proposed method limits the motor currents during starting period and reduces commutation torque ripple during sensorless operating period. Experimental results show that the proposed method implemented in an inverter for a BLDC motor driven compressor considerably reduces not only the pulsating currents but also vibration of the home appliances.
