Nowadays, low cost manufacturing and high speed electric motors are still big challenge with Vietnamese electric motor companies because current design and manufacturing technologies are poor and backdate due to lack of modern design tools. Moreover, their producing technologies were developed from 1980s with co-operation of Russia and Hungary. The traditional designs and technologies are not yet updated with new magnetic materials. Modern Finite Element Method (FEM) for design and evaluation of electrical motor has not applied to improve efficiency.
Currently, only induction motors with are made by Vietnamese electrical motor manufacturers such as Hanoi Electromechanical Manufacturing Company (HEM) and Vietnam Hungary Electrical Manufacturing Company (VHEM). Therefore, their motor can apply only for ventilation and pumps. They are also unable to produce other kinds of motors with high performances such as Switched reluctance motors, BLDC motor, IPM and Servo motors. In coming time, if they want to increase their competitive abilities in the markets or give out more products they have to produce other kind of motor with high performance and low manufacturing cost. Modern designs and advanced technologies of electric motors for industrial electromechanical manufacturing companies are very necessary and high demands. However, industrial companies have no scientific experts and R&D center for improving current products. .
In order to maximize efficiency, torque and power performances, advanced technologies have to apply in designs, developments and manufactures. Therefore, many novel approach have been applied to optimize electromagnetic structures. A Finite Element Method (FEM) is widely used to design geometry diameters of stator, rotor teeth and magnet shapes
