Optimum Design of a Five-phase Permanent Magnet Synchronous Motor for Underwater Vehicles by use of Particle Swarm Optimization
Abstract: Permanent magnet
synchronous motors are efficient motors which have widespread applications in
electric industry due to their noticeable features. One of the interesting
applications of such motors is in underwater vehicles. In these cases, reaching
to minimum volume and high torque of the motor are the major concern. Design
optimization can enhance their merits considerably, thus reduce volume and
improve performance of motors. In this paper, a new method for optimum design
of a five-phase surface-mounted permanent magnet synchronous motor is presented
to achieve minimum loss and magnet volume with an increased torque. A
multi-objective optimization is performed in search for optimum dimensions of
the motor and its permanent magnets using particle swarm optimization. The
design optimization results in a motor with great improvement regarding the
original motor. Finally, finite element analysis is utilized to validate the
accuracy of the design.
