Abstract:
In order to improve efficiency across a range of applications, brushless direct current (BLDC) motors are being used to replace induction motors. This paper explores the feasibility of utilizing a single-phase BLDC motor for external fan applications with respect to operation incident external airflow and in mitigating their increased torque ripple. A method for improving alignment to support different startup conditions is also described. Compensation for increased torque ripple is addressed by both changing motor construction and control methods. Finally, a Hall-based imbalance handling algorithm is also proposed.
