Abstract

Torque ripple is a major concern in slow speed and pointing applications. Hence This paper aims in the analysis of torque ripple of multiphase BLDC motor. A five phase 3.2 Nm, 10000 rpm Trapezoidal type BLDC motor is chosen for analysis. Simulation is carried out for controlling the speed of five phase BLDC motor in MATLAB R2013a. Block level simulation is carried out in SIMULINK with the decoder logic subsystem, controller, driver and MOSFET switches.The speed profile is analysed for various speed input commands over the full range up to rated speed. Torque ripple is studied and it is compared with the same capacity three phase BLDC motor. The input voltage required for the full range of speed upto rated speed is obtained from simulation results. Controller fine tuning is carried out for smooth and precise speed control.
