Description

technical field [0001] The invention relates to the field of microwave oven components, in particular to a novel brushless microwave oven cooling fan motor. Background technique [0002] In the prior art, a microwave oven is generally equipped with a transformer, and the transformer is installed below the magnetron at the bottom of the oven cavity. When the microwave oven operates for a period of time, the temperature of the transformer rises rapidly. In order to cool the internal components of microwave ovens, blow away the water vapor generated by food, and dissipate heat from transformers and magnetrons, cooling fan motors are generally installed in microwave ovens. However, the existing cooling fan motors for microwave ovens generally use shaded pole motors, which consume a lot of power. , the noise is loud, and it is not in line with the current energy-saving environment. [0003] In order to overcome the above defects, the present invention makes beneficial improvemen...
