Optimal Design of Axial Flux Permanent Magnet Synchronous Motor for Electric Vehicle Applications Using GAand FEM

Axial Flux Permanent Magnet (AFPM) machines are attractive candidates for Electric Vehicles (EVs) applications due to their axial compact structure, high efficiency, high power and torque density. This paper presents general design characteristics of AFPM machines. Moreover, torque density of the machine which is selected as main objective function, is enhanced by using Genetic Algorithm (GA) a...

Digital Control of Permanent Magnet Synchronous Motors

Permanent Magnet Synchronous Motor (PMSM) variable-speed drive is widely used in the industry because of its particularly high mechanical power density, simplicity and cost effectiveness. Eliminating the mechanical sensor mounted on the shaft of the motors gives further improvement. These drives are referred to as “sensorless” electrical drives. In this paper a novel sensorless algorithm is pro...

Novel Torque Control Technique for High Efficiency/High Power Interior Permanent Magnet Synchronous Motors

HV The motors of hybrid electric vehicles must be able to offer high efficiency, a high power/weight ratio, and excellent reliability across the entire rotor speed range. Interior permanent magnet synchronous (IPM) motors are used to satisfy these requirements. The goal of this study was to develop an IPM motor control method that would increase the torque and the efficiency at high and medium ...

Study on interior permanent magnet synchronous motors for hybrid electric vehicle traction drive application considering permanent magnet type and temperature

Recently, interior permanent magnet synchronous motors (Interior-PMSMs) have become known as a good candidate for hybrid electric vehicle (HEV) traction drive application due to their unique merits. However, the dynamic and steady-state behaviors of these motors are quite dependent on the permanent magnet (PM) type, configuration, and volume in rotor structures. This paper uses a novel structur...
