Abstract

In this paper a novel configuration to a low cost converter which make a spindle motor at lofty speed with high starting torque employing the bipolar starting and unipolar running algorithm is proposed. This topology is straightforward and developed with merely eight switches in the converter to drive the spindle motor at elevated speed with high starting torque. These motors are mainly used in electric vehicle (EV) applications because of its high speed and compact size. In order to read and write the enormous data with quick rate, the spin speed of spindle motor should be high with high starting torque. The proposed topology has been controlled with fuzzy controller and its performance is compared with conventional PI controlled drive. The proposed concept can be implemented with MATLAB/SIMULINK software, to verify the speed response with PI and Fuzzy logic controllers.
