Abstract

A Hard Disk Drive (HDD) spindle motor is a brushless dc (BLDC) motor which has been used in high speed applications due to its high efficiency and good controllability. This paper presents a novel topology for a low cost converter which drives a spindle motor at high speed with high starting torque using the bipolar starting and unipolar running algorithm. This topology is simple and uses only eight switches in the converter to drive the spindle motor at high speed with high starting torque. The proposed scheme has been simulated on MATLAB/SIMULINK platform, the results are presented and discussed. The proposed topology is best suited for low power drives.
