“…There are two basic approaches to couple electromagnetic field with circuit simulation. One is the direct coupling approach where Maxwell 2D and 3D FEA models can be solved simultaneously with a transient circuit system simulation model [21][22][23]37]. Namely, a direct coupling co-simulation is achieved by a data exchange between transient solvers during each time step.…”

This paper introduces the detailed coupled field-circuit analysis including performance characteristics of a 4-kW in-running rotor permanent magnet synchronous generator (PMSG) used in rural-type small-scale wind turbines for water heating purpose. The content of the work consists of design, analysis, optimization, production and testing processes and validation studies. An integrated 2D electromagnetic field and circuit model are used in the design and analysis processes. The electrical machine design involves complex and time-consuming processes. This model provides comprehensive information on machine behavior under different conditions and is an effective to demonstrate compliance with real load conditions prior to the manufacture. The goal of the optimization process is to find a design that offers cost, manufacturability and efficiency as well as generator output values. For this, a multiobjective optimization approach has been used. Typical design and simulation principles are applied to the designed PMSG, respectively, including calculation and evaluation of various output parameters for different simulated wind speed rates and varying load conditions. Furthermore, the analytical studies related to finite element methods and parametric approaches are presented in collaboration with experimental studies carried out for different load rates.

“…Permanent magnet synchronous generator (PMSG) has received much attention in wind energy operation because of their property of self-excitation (no need of field winding and unreliable slip ring and brush), which allows an operation at a high power factor, efficiency, stability and reliability. A direct driven PMSG which can be connected with gearless, multiple numbers of poles to generate power at lower rotational speed, is also very attractive due to lower weight and better wind energy utilization [1], [2]. Some of the weakness of these generators include their large size (due to the high torque rating), requirements for large quantities of rare earth permanent magnets and the significant generator structures [3].…”

“…Considering the large air gap between the stator and rotor and the small mass of the MG rotor in these systems at high speeds, the transient processes will have a different characteristic compared to electric machines with permanent magnets with a rotational speed not higher than 60,000 rpm whose transients are well described in publications [22,23]. That is, it is not possible to make full use of known articles on transient processes in electric machines with permanent magnets [22,23] to assess the performance of MG in emergency operation modes.…”

Abstract-The article presents a research of the effect of different types of short circuits (SC) on the performance of the gas turbine and ultra-high-speed microgenerator (MG) in a wide rotational speed range (from 200,000 rpm to 1,000,000 rpm) at a power from 10 W to 1 kW. The studies are carried out on a specific two-pole 100 W 500,000 rpm microgenerator with permanent magnets with a toroidal winding. The research is carried out by finite element method using Ansys Maxwell software. Numerical study by the finite element method is performed at the rated operation mode and various types of short circuits: single-phase, two-phase, three-phase circuits coil inside MG. By the results of these studies, we estimate a negative impact of different types of faults on the parameters of MG and the mechanical characteristics of the gas turbine. Also various options MG with SC for various types of bearings were considered. Then, using the full-sized 100 W sample we carried out experimental studies of the MG operation in nominal operation mode at the 500,000 rpm. That allows to verify the developed computer model and confirm the results of our practice research. The obtained results can be used in the aerospace industry for design the high reliability complexes such as new energy systems for satellite power supply, unmanned aerial vehicles and microturbines. In addition, it can be used to design the ultra-high-voltage electric machines with a high fault tolerance for the compressor plants, air supply systems of hydrogen fuel cells, new medical tools and machine tools.
