Design and production of a double-sided slotted axial flux permanent magnet synchrounous motor for electrical vehicles

In recent years, interest in electric vehicles (EV) has been increasing. The most important reasons are environmental pollution caused by the density of cars in large residential centers, depletion of fossil fuels, the world's shortage of energy resources, advances in efficient and cost-effective electric motor and drive technology, improvements in batteries that store electrical energy and driving safety. One of the most important factors that provide energy efficiency in electric vehicles is the motor. The axial flux permanent magnet synchronous motor (AFPM), which is a dominant magnet in the field of motor, has many advantages over other types of motors. Since there is no excitation zone, the efficiency is higher due to the significant reduction of rotor losses. In addition, one of the major advantages of AFPM is the high power density. AFPM are also superior in terms of vibration and noise levels. Besides, they have an easily adjustable airgap. Its direct integration into the system is also important feature for use in EV. In this thesis, double rotor AFPM is designed and this motor is called as TORUS motor in literature. The most prominent feature of this motor is that it can produce high torque even at low speeds. In addition, their efficiency is higher than other motors. In this study; information about AFPM and the optimization method used in the design of TORUS motor, which is a member of this motor class. TORUS motor design equations were removed, optimization, analysis, and production was carried out.
