Brushless PM Motor Design Workshop with System Focus

MagNet, ElecNet and ThermNet v7.2 Now Available

ElecNet and ThermNet now offer the same seamless and easy coupling that is already available with MagNet and ThermNet. Performing a coupled analysis determines the non-linear steady state temperature distribution due to electric heat sources for both static and time-varying thermal simulations. The coupling works with the transient, current flow and time-harmonic electric field solvers in ElecNet

The new adiabatic feature available in ThermNet and can be used for both coupled MagNet and ElecNet simulations.  The adiabatic features models sudden and rapid heating, such as lightning strikes.

Version 7.2 also introduces the multicore feature to post-processing for even faster results and transparency for improved visualizations.

MagNet, ElecNet and ThermNet v7.2 are now available. Maintained clients can visit to download the software or read the release notes for full details.

To request an evaluation, live demo or pricing information, please contact your local Infolytica Corporation representative.

Thermal Characteristics of a 330 kV Surge Arrester

Surge Arrestor
Surge arresters are used in a number of industries as protective devices against a variety of electrical events such as high voltage lightning impulse. The design choices of various materials and components for lightning arresters may depend on their thermal characteristics among many other factors. To demonstrate this, the thermal analysis of a 330 KV metal oxide arrester is considered in this example. The adiabatic heating of the varistors due to a lightning strike and the subsequent temperature distribution in the device as a function of time are presented here

Webinar: Coupling ElecNet and ThermNet

Date and Time: June 15, 2011 1:30 pm, EDT (GMT-4:00)
Register Today

With their new coupling feature, the power loss data from ElecNet can be used as a heat source in ThermNet, allowing users to determine the impact of temperature changes on the overall design and performance.

This new capability is just one amongst the many existing that has made ElecNet a well-known and trusted electric field simulation package, offering engineers an accurate and fast design tool.

This free one hour event will cover the new features available in this latest release. The demonstration will focus on using ElecNet and ThermNet to simulate a surge arrestor. You can also put forth your own questions to our application specialist.

Design and Modeling of Dual Fed Asynchronous Generators: Application to Wind Power Generation

Pre-Conference Tutorial at ECCE 2011
September 17-22, 2011 in Phoenix, AZ

The design and modeling of dual fed induction generators is considered in this tutorial. The topic will be covered by using examples that are focused primarily for wind power generation applications. The tutorial will begin with an overview of such systems and component identification. The design and modeling methodologies and challenges of various components will be discussed then. This will be followed by discussions on the design of induction generators and their field oriented control strategies. Topics covered will include design strategy for initial design (sizing, material and winding designs), load point analysis, and machine performance etc. Multi-physics aspect (electromagnetic, thermal, and mechanical) of the design algorithms will also be discussed. Aside from generator design, there will also be some general discussions on inverter topology and simulation specific to such devices. Modern computer aided design software will be used to illustrate the various design and simulation strategies related to such systems. As well, a literature review will accompany the presentation to highlight the state-of-the-art of such systems.

Please visit the website for ECCE 2011 for more details about this tutorial.

Brushless PM Motor Design Workshop with System Focus

June 8-9, 2011  - McLean, Virginia
$895 USD

STG (Strategic Technology Group LLC) has organized a workshop to address three important elements of a brushless PM motor system:
  1. Brushless PM motor design
  2. Simulation, algorithm & software development
  3. Power stage design
The goal of the workshop is to address all these topics from a systems' perspective and not in isolation. STG and its staff have had a proven record of developing and commercializing a number of 3-, 5- and 7-phase brushless motor systems for various industrial, medical and consumer applications.

The workshop will cover several example designs and simulations using MotorSolve by Infolytica, PSpice™, Simulink™ and VISSIM™.
