The axial-flux machines have been gaining popularity thanks to their higher torque density and short axial length compared to radial-flux machines. However, they are not easy to mass manufacture because of their thin form factor. Printed circuit board (PCB) technology offers a solution to the problem by utilizing the highly developed, precise, and consistent PCB manufacturing process. However, having a low copper fill factor and low inductance are the main disadvantages of the PCB motors. This thesis focuses on the design and development of double rotor single stator axial-flux permanent magnet synchronous machines with PCB stators. Multi-objective optimization algorithms are used and compared in order to improve the torque density with the developed analytical cost function of the PCB motors. The comparison of several stator winding topologies is investigated to find out which winding shape is suitable in different applications. The analytical calculation methodology of induced phase voltage and output torque of wave windings are developed and compared with test results. An integrated motor drive PCB motor with gallium nitride (GaN) switches at a 1 MHz switching frequency is developed to overcome the problem of low inductance. The motor is optimized using the constructed model, and the non-dominated sorting genetic algorithm (NSGA-II) and two stator types are designed to compare the effect of unequal trace width. A mechanical and thermal solution is offered by utilizing the copper traces of the stator board and the housings. The system is tested in both generator and motoring modes under various load conditions up to 7000 RPM. The overall system efficiency is found as 82% at rated torque with feed-forward compensated field-oriented control (FOC).

Mechanical and Thermal Design of an Optimized PCB Motor for an Integrated Motor Drive System with GaNFETs Tokgöz, Furkan; Gulsuna, Ozgur; Karakaya, Furkan; Çakal, Gökhan; Keysan, Ozan (2022-01-01) PCB motors are a viable alternative to commercial electric motors as they are easy to mass-produce and have low manufacturing costs. Moreover, integrated motor drives have gained popularity thanks to their high power density and ease of installation. However, the mechanical and thermal aspects are challenging due to reduced volume. In this paper, a GaNFET switched integrated motor drive axial-flux permanent magnet synchronous machine with a printed circuit board (PCB) stator is designed. The machine is opti...
Design of a GaN Based Integrated Modular Motor Drive Uğur, Mesut; Keysan, Ozan (2018-10-25) In this study, design procedure of an Integrated Modular Motor Drive (IMMD) is presented focusing on high power density. The design is based on a permanent magnet synchronous motor (PMSM) and GaN FETs. Fractional slot concentrated windings are used on the stator. Slot/pole combination and winding configuration is selected based on having low cogging torque and high winding factor. An extended motor drive inverter topology is proposed where 2-level voltage source inverters are connected both in series and pa...
Design optimization of variable frequency driven three-phase induction motors Ertan, B; Leblebicioğlu, Mehmet Kemal; Simsir, B; Hamarat, S; Cekic, A; Pirgaip, M (1998-01-01) An approach to optimize the design of three-phase induction motors for a wide speed range drive is considered. Two operating points in the speed range are taken into consideration. The problem is handled as a constrained optimization problem. An accurate model for the motor in terms of its dimensions has been developed which predicts the motor performance based on about 60 parameters of motor geometry.
Design, Development and Implementation of Sensorless Digital Control of an Electric Motorization Dida, Abdelkader Hadj; Bourahla, M.; Ertan, Hulusi Bülent; Benghanem, M. (2014-09-24) The most industrial applications use the variation of the torque, speed and/or position in process, for which extremely severe specifications are needed. In the field of the drive of the electric machines, the elimination of the mechanical speed sensor can present an economic interest and improve safety of operation. One thus tries to make fulfill the speed measurement by implementing in a Digital signal processor (DSP) an algorithm of speed estimation using the current and voltage acquisition. Those method...
