A systematic approach to the design of electrical machines is implemented by solving problems analysis and synthesis in various combinations at different stages design. The questions formulation implementation study modular-type magnetically commutated are considered. They aimed reducing weight, size cost while improving performance these newly designed machines. complex method parametric an au...

Axial field flux switching motor with sandwiched permanent magnet (AFFSSPM) is a novel of flux switching motor. Based on the vector control method, the mathematical model of the AFFSSPM is derived and the operating performance of the AFFSSPM in the overall operating region is investigated.A novel control method for the AFFSSPM drive system, including the id =0, maximum torque per ampere, consta...

This study investigates the tonal high frequency noise characteristics which are present within the cabin of an electric vehicle. As the human ear responds differently to different frequencies of sound and this response varies with age, both the level and the frequency are considered. In addition, the amount of annoyance these sounds will cause for the occupants is a function of the tonality an...

An electric traction machine for an electric or a hybrid electric vehicle is usually designed for a specific operating point or cycle. For such an operating point or cycle, the masses and the cooling circuit of the electric machine determine the time dependent temperature distribution within the machine. For a specific load cycle, the thermal simulation of the machine can reveal possible mass a...

The interest in adopting electric actuation in Navy ships, and in particular in submarines, usually founders on the issue of the mass and volume of electric actuators, which are perceived to be significantly worse than those of competing technologies. Certainly looking at the volume, mass, power and torque of a typical 3 phase induction machine, even in comparison with a typical automobile engi...

This paper presents how losses of electric machines are modeled as an extension of the Modelica.Electrical.Machines library. The theoretical background of the different loss models is elaborated and a Modelica implementation – the AdvancedMachines Library – is presented. Additional examples demonstrate the usage of the library.

Almost all electricity in the UK is generated by rotating electrical generators, and approximately half of it is used to drive electrical motors. This means that efficiency improvements to electrical machines can have a very large impact on energy consumption. The key challenges to increased efficiency in systems driven by electrical machines lie in three areas: to extend the application of var...

This paper presents a study on the application of fuzzy logic theory to control a directdrive dc motor. The design of fuzzy logic controller for speed of a DC motor is presented. Control performance of the fuzzy logic controller is studied by simulation. The simulation results with fuzzy control are compared with those of the conventional controller. 15:30 – Presentation of a Control Law for IM...

The rugged low-cost construction and constant power profile of a switched reluctance motor (SRM) make it suitable for hybrid electric vehicles (HEVs). This paper describes the development of a voltage-based control strategy for a SRM. The controller design is influenced by project constraints and goals as well as the use of a new power topology. A prototype SRM and controller were built and ful...
