Abstract
In recent years, the use of permanent magnet synchronous machines with fractional slot concentrated windings has received much attention in the industry. Also, the increasing need to use renewable energy sources has led to more and more attention to electric vehicles, including electric cars and electric-hybrid cars, which has led to the reduction of fossil fuel consumption and also reduce the emission of greenhouse gases. In order to achieve high power density and high torque density in applications such as electric vehicles drives, electric compressors, electric car fans, air compressors for heavy vehicles, elevators drives, etc., the processes related to the design of these machines is very important. Also, the advantages of concentrated winding include high power density, high efficiency, short end winding, high slot filling factor, low cogging torque, the ability to work in wider flux weakening region and the ability of higher fault tolerant. In this thesis the design and control of several interior permanent magnet synchronous machines with fractional slot concentrated windings with different number of poles and slots using the maximum torque per ampere control strategy in order to achieve an optimal combination of pole number and slot number, increasing efficiency and reducing parasitic effects including torque ripple, vibration and acoustic noise have been discussed. With the help of this control method, the required torque can be provided with the lowest amount of current.
