초록
The rotor of the BLDC motor has permanent magnets on its surface, and is alike the structure of the rotor of synchronous motors. When designing the BLDC motor which has a limited volume in a specific environment, it is important to consider the geometry of the rotor and the length of the airgap. This paper describes a design procedure by analyzing the induced voltage and cogging torque with changing the width of magnets and length of the airgap. And we made a prototype of BLDC motor with this design procedure and our experiment result shows that the cogging torque can be reduced significantly. Also we find a good agreement between the result of experiment and simulation values using Finite Element Analysis.
