“…The optimization methodology applied in this paper has been used in previous PMSG design to minimize the active material cost being validated by a prototype [3]. The strategy of including the cost of losses as a part of the PMSG cost has been proposed previously by Grauers T. de P. M. Bazzo, J. F. Kolzer, R. Carlson that considers an average cost of losses obtained prior to the optimization process is carried out [4].…”

This paper shows the results of an optimization strategy that takes into account the annual wind profile of a wind turbine to minimize the generator cost and maximize the energy yield. The optimally designed machine is a 3-phase permanent magnet synchronous generator with 48 poles and 30 kW for direct drive wind turbines. The energy yield is considered in the optimization method by including the cost of losses in the objective function, which is then the sum of cost of losses, cost of materials and structure costs. To show the advantages of employing this strategy, the results of a standard optimization strategy, which minimizes the generator costs not regarding energy production, are also presented and compared. It is shown that this strategy results in a machine that produces more energy during its lifetime, which compensates its higher cost. Finite element analysis software is used to verify and validate the resulting machine.

“…Thanks to all these benefits, HSEMPM is widely used in aircrafts such as F-35 [2], spacecrafts and satellites [3][4][5], in hybrid vehicles [6][7][8], ships, machine-tool industry, turbochargers, and medicine. HSEMPM are also used in virtually all distributed power generation plants (Capstone, Elliot, Turbec) [9][10][11][12].…”

Abstract-This paper solves the problem of minimizing losses in the stator magnetic core of high-speed electric machines with the use of amorphous iron. A fundamentally new technology for manufacturing of a stator magnetic core from segments of amorphous steel is developed by the authors. The feature of the new stator design is the possibility to use technological ducts located inside the stator as cooling ducts. This aspect significantly improves the heat dissipation from the active zone of the stator and, accordingly, minimizing temperature. The efficiency of this solution was studied using two power generators of 100 kW and 200 kW and rotational speeds of 60,000 rpm and 45,000 rpm respectively in the software complex Ansys Maxwell. Harmonic compositions of currents and voltages, flux density distributions in active elements of the generator in various operating modes were studied: under load, in a three-phase short-circuit and at idle. Also, the obtained data were compared with analogous models of an electrogenerator made of electrical steel. The results of the study showed the operability and effectiveness of the proposed technology. Based on the results of the research, a prototype of the stator magnetic core made from amorphous iron was created. Losses in the generator were experimentally measured. Also the results of experimental studies of aerodynamic losses are presented.
