“…Furthermore, the problem of impossible self-starting, which had been the biggest weakness of synchronous motor, was resolved by magnetic pole position detection and improved control performance, to the extent that even micro speed control became possible. On the other hand, because the rotor of a motor is connected directly to the mechanical load rotating at high speed, stable stress distribution is essential and it should be designed to fully tolerate critical speed [5][6][7][8][9]. Therefore, an important technology is the structural design of the motor.…”

-Recently, the interior permanent magnet (IPM) motors for electric vehicle (EV) traction motor are being extensively researched because of its high energy density and high efficiency. The traction motor for EV requires high power and high efficiency at the wide driving region. Therefore, it is essential to fully consider the characteristics of the motor from low speed to high-speed driving regions. Especially, when the motor is driven at high speed, a significant centrifugal force is applied to the rotor. Thus, the rotor must be stably structured and be fully endured at the critical speed. In this paper, aims to examine the characteristics of the IPM motor by adjusting the width of air-barrier according to the permanent magnet position which is critical in designing an IPM motor for EV traction motors and to conduct a centrifugal force analysis for grasping mechanical safety.

“…Another objective is to obtain the proper number of stator slots per pole for two winding distributions [8]. Moreover, this paper presents an optimal design process for selected winding based 3 kW PMaSynRG, to achieve a wide constant power speed range (CPSR), high efficiency, and good power factor using the LPM and the DES [9,10]. Furthermore, iterative processes are performed for minimizing cogging torque and torque pulsations, until results of LPM and FEA predictions are converged.…”

In this paper, design and performance analysis of robust and inexpensive permanent magnet-assisted synchronous reluctance generators (PMa-SynRG) for tactical and commercial generator sets is studied. More specifically, the optimal design approach is investigated for minimizing volume and maximizing performance for the portable generator. In order to find optimized PMa-SynRG, stator winding configurations and rotor structures are analyzed using the lumped parameter model (LPM). After comparisons of stator windings and rotor structure by LPM, the selected stator winding and rotor structure are optimized using a differential evolution strategy (DES). Finally, output performances are verified by finite element analysis (FEA) and experimental tests. This design process is developed for the optimized design of PMa-SynRG to achieve minimum magnet and machine volume as well as maximum efficiency simultaneously.
