Abstract

It is recent trend that the manufactures of refrigerator use BLDC motor which RPM is changed by voltage of DC power, instead of induction motor in order to reduce energy consumption and noise radiation. It can be controlled two or more RPM suitable to environmental condition. For example it is operate much lower RPM than normal(usual) in the night. This paper introduce the method of noise control in the case of using BLDC Fan motor for refrigerator.
