Infolytica Corporation today released new versions of their industry-leading MagNet, ElecNet, ThermNet and OptiNet simulation software. There are many significant improvements and new features in this release, including improved nonlinear material treatment in AC/time-harmonic simulations and expanded circuit modeling tools for complex control systems. A virtual prototype that is increasingly realistic – that is the driving force behind the improvements and new features in MagNet, ElecNet, ThermNet and OptiNet v7.8. The suite of computer aided engineering software can handle the most complex electromagnetic and electric field simulation requirements. Engineers, scientists or designers can simulate the real physics and complex systems which impacts the electromagnetic fields or electric fields and in turn, the predicted performance of a device or component. The design of electric transformers, motors, inductors and other ferromagnetic-cored devices require accurate treatment of nonlinear effects, which also affect the accuracy of iron losses. Transient solvers that have significantly longer solution times, accurately handle nonlinear effects. Solution times, nonlinearity effects and losses are important in the design of large devices such as power transformers. Time-harmonic solvers balance the need of fast solution times and non-linear approximation. The MagNet 7.8 release improves the nonlinear approximation of the time-harmonic solvers, such that the accuracy of the iron losses is close to that of a transient solve with a 90 % reduction in solution time, as shown in the table below. The table compares the results of the two solvers in a 100 kVA single-phase power transformer. The accuracy of the iron losses with respect to the transient solver is further confirmed by the iron loss distribution (W/m3) as seen in the following figures. Switching effects in nonlinear inductors, transformers and rotating electric machines can be analysed within MagNet 7.8, by including current and voltage controlled switches. Accounting for switching effects, in addition to core nonlinearity, gap and 3D effects, will significantly improve the design of inductors used in switch-mode converters and power supplies, and the design of wireless power transfer coils. A 3D MagNet model incorporating controlled switches in its circuit can fully consider these effects. For example, the following 27 kW boost converter circuit steps-up the battery voltage from a DC bus voltage of 200 V up to 650 V, for an electric vehicle drive. The PWM driven voltage controlled switch regulates the output voltage, and can be used to analyze the effect of switching frequency on inductor losses. A current controlled switch can be used to regulate the inductor or load current. The inductor average current was regulated to around 40 A as shown in the next chart using a current controlled switch. The instantaneous inductance was then determined from the energy and flux linkage methods, whose average is about 420 μH, as seen in the inductance chart. MagNet, ElecNet, ThermNet and OptiNet v7.8 are now available for Microsoft Windows 7, 8 and 10.

This paper proposes a neural network (NN) based noise prediction model for electric machines, applied to the case of synchronous reluctance motors (SynRMs). The natural frequencies of various vibration modes for a SynRM stator with generalized tooth geometry and slot numbers have been obtained using structural FEA based computations and then used to build a NN based surrogate model. The accuracy of the surrogate model has been tested and applied to predict the noise level in SynRMs. Also, varying trends in the noise levels for single-barrier SynRMs have been analyzed as a function of the rotor's flux carrier and barrier widths using the natural frequency prediction model. © 2016 IEEE.

In this paper, the effect of different excitation patterns on both the iron loss and flux inside solid magnetic steel plates and laminated silicon steel sheets is investigated. Some practical approaches to nonlinear and anisotropic eddy-current problems under 3-D excitation conditions are proposed, in which the usual measured loss data is not adequate within the penetration depth where the eddy currents are induced by fluxes normal to the lamination. The benchmark results based on member models of Problem 21 with new extensions are presented to validate the proposal and to observe the electromagnetic behavior of the magnetic steel under different excitation patterns. The extensions to the benchmark Problem 21 are helpful for further Testing Electromagnetic Analysis Method (TEAM) activities. © 2006 IEEE.

The measurement and 3D finite element analysis of the iron loss, interlinkage flux inside the laminated silicon steel sheets and the magnetic flux densities at the specified positions are carried out based on a verifying silicon steel sheet model. The modeling results show that the leakage flux vertically through the silicon steel sheets has the peculiarity of shin effect, and the eddy current loss caused by the AC leakage flux is a significant component of the total iron loss. The calculated results by means of the software MagNet® agree with the measured ones, and show the method presented in this paper is validated.

The effect of the variation of B-H properties obtained by different means and data access modes on iron loss and flux in grain oriented (GO) silicon steel laminations is investigated under different exciting frequencies in order to determine an efficient numerical approach to model the lamination configurations. The computational and experimental results are demonstrated on benchmark models in which the 3-D excitation and skin effect play a significant role. © 2011 IEEE.

Infolytica Corporation today released a new version of their industry-leading MotorSolve software. The motor results in MotorSolve BLDC version 6 can be extended with a new generator analysis solver. This set of loads, parameters and results are for both AC generators and motors operating in generating mode. Any electrical machine template in the BLDC module can be simulated in motor mode or generator mode, depending on the operating condition. An optimal generator design will be different to an optimal motor design. Most software tools use the fact that motors can act as generators and address only motors. MotorSolve v6 addresses the need for a specialized generator design tool. Using MotorSolve version 6, AC generators (PMG, PMA, and Brushless AC) and motors operating in generating mode can be properly simulated and analyzed. There are five common load types available: diode rectifier, no load or open circuit, short-circuit, passive impedance loads and infinite bus (connection to a large AC system or grid). The operating points conditions can be analyzed at maximum power and short-circuit current. Performance charts for generators include voltage regulation, voltage vs. current, power vs. speed and many more. Phasor diagrams for both motors and generators have also been added in the latest update to the software. There have been improvements to the winding diagrams, as well, with three new options added: Görges plot, MMF plot and an animated MMF plot. Cogging Torque for a BLDC machine: the minimum skew required to produce zero cogging torque is shown as an option for the user. The inline help of MotorSolve now includes new video tutorials which demonstrate how to use the different features of the software, making learning easier and faster. MotorSolve v6 is now available for Microsoft Windows 7, 8 or 10. For information about the full list of improvements, request a demo, quote or full feature evaluation, please contact an Infolytica Corporation representative nearest you.

Hardware-in-the-loop simulation allows hardware implementations of some components of a system to be tested in conjunction with other components that are only emulated based on behavioral models. For example, a physical prototype of an engine control unit for a hybrid vehicle can be tested with virtual prototypes of the motor and vehicle. This paper presents a new method to obtain realistic behavioral models of PM synchronous machines from finite element analysis. The new method guarantees that the model will be internally consistent; for example, it will not violate the principle of conservation of energy. © 2014 IEEE.

The goal of this paper is a method for the simulation of an induction motor driven with a pulse width modulation (PWM) three-phase bridge. The approach taken here decouples the circuit simulation from the electromagnetic field simulation by first constructing a performance model of the machine using 2D finite element (FE) analysis. The model consists of the complete matrix of the self- and mutual inductances of the stator windings and each of the rotor bars. Skew is taken into account by a correction applied to the winding-bar inductance entries in the matrix. © 2006 IEEE.
