Modeling and Simulation of Multiphase BLDC Motor Drive Systems for Autonomous Underwater Vehicles

An Optimized Speed Controller for Electrical Thrusters in an Autonomous Underwater Vehicle

“…The electrical and mechanical systems of a hydro quad rotor has been designed and implemented using Brushless DC motors as thrusters motors in order to study its static stability at various depths [6]. A seven phase BLDC motor for the propulsion of AUV has been functionally modelled and simulated in MATLAB/SIMULINK for studying its dynamic characteristics [7]. The analysis of electrical characteristics using Finite Element Analysis along with a comparative analysis of PI and Fuzzy controller has been done for a seven phase BLDC motor [8] 1167 is mechanically designed as a low cost thruster in AUV has been studied for its compatibility in a depth of more than 1 meter [97].…”

Speed Control of an Eleven-Phase Brushless DC Motor

“…Multiphase PMBLDCMs have some advantages in compare with traditional three-phase PMBLDCMs that have been listed in the following [1], [6]:  low amplitude of torque pulsations  high frequency of torque pulsations  high torque per ampere ratio in comparison with a similar machine volume  low phase current of stator without increasing phase voltage  high reliability  high power density A.
