Implementation of food processor application using Brushless DC Motor control

Food processor requires wide range of variable speed response. Going on the trend of energy saving and carbon reduction, household and commercial using of food processor operation efficiency be much more paid attention to. At the present stage, food processor is mainly with UM and IM. While the operating efficiency and noise cause users must find new solution. Energy conservation, high efficiency SRM and BLDCM become to the market´s rising star. Current technology shows that the efficiency of BLDCM is higher than that of the SRM. Analysis and experiment for BLDCM required motion behavior control on the instant speed up, switching forward / reverse and braking in the food processor operation are discussed in this paper. The most suitable food processor required motion behavior control methods are provided. Experimental results proved that the proposed methods in fast dynamic response of food processor do never cause the system voltage and current unstable or over load condition.
