| Abstract |
This paper presents a optimization design of the single phase BLDC motor applied Notch shape. Cogging?Torque causes noise, vibration and torque ripple,?so?notched stator is proposed in this paper. Firstly, a single phase BLDC motor needs applying asymmetric air-gap shape because this type motor cannot help having dead-point which is zero torque position. However, using asymmetric air-gap structure causes cogging torque increase. Therefore, this paper proposes the notch shape structure. Notch shape structure has some advantages;?and?low cost, easy to apply. There are 4 optimal factors selected in optimization process, which are position and size of notches.?The result of FEA and the experimental measurement value?using the developed prototype?are?compared each other and then vailidity and utility of simulation?will be?verified. |
