Model Order Reduction for Rotating Electrical Machines
The simulation of electric rotating machines is both computationally expensive and memory intensive. To overcome these costs, model order reduction techniques can be applied. The focus of this contribution is especially on machines that contain non-symmetric components. These are usually introduced during the mass production process and are modeled by small perturbations in the geometry (e.g., ...
متن کاملOverview and Comparison of Iron Loss Models for Electrical Machines
One important factor in the design process and optimization of electrical machines and drives are iron losses in the core. By using new composite materials and low-loss electrical SiFe steels, the losses in the magnetic ux conducting parts of the machine can be reduced signi cantly. However, it is necessary to have accurate but also easy implementable iron loss models to take the loss e ects in...
متن کاملNew high-efficiency protective coating containing glycidyl-POSS nanocage for improvement of solar cell electrical parameters
Various antireflection thin films are often used to cover glass to increase solar cell electrical parameters. In the recent years many efforts have been done to develop and improve of solar cell films with high electrical output. One of the most important challenges of obtaining of high-efficiency thin films of solar cells is creation an effective light trapping system. The new polymeric protec...
متن کاملCalculation of Local Iron Loss in Electrical Machines Using Finite Elements Method
Calculations of iron losses in the electrical machines are normally based on experimental characteristics of core material used in the machines. These methods with simplified machine analysis approximations are usually employed for calculation of total iron losses of electrical machines whilst local flux densities and corresponding local iron losses especially when designing of the machine and ...
متن کاملSlot Design for Dynamic Iron Loss Reduction in Induction Machines
The goal of this paper is to present a semi analytical method which makes it possible the calculation of the dynamic iron losses in a three phase induction machine taking the slotting effect into account. The particularity of this method is that it allows the distinction of the stator and the rotor slot openings contribution in the dynamic and, consequently, in the total iron losses. This analy...
