초록
This paper proposes a novel starting method of a high speed induction motor with air bearings for turbo blowers. The friction of air bearings varies according to rotating speed, operating temperature and usage time. Specially, friction torque at initial starting state under low bearing temperature usually results in starting failures of the conventional V/F control method. Therefore, this paper proposes a new starting method, which consists of an initial I/F control mode and smooth transition method to V/F control mode to overcome the starting failure. The experimental results are shown to verify the analysis and the usefulness of the proposed method.
