Abstract
This paper presents the improvement of dynamic characteristics in interior permanent magnet (IPM) type BLDC motor with notch. The notch is applied on the surface of the rotor to reduce the cogging torque and to improve dynamic characteristics. The current, inductance and torque of initial model and optimal model are analyzed by FEA. The validity of improved dynamic characteristics is confirmed.
