The development of an electric motor is a highly complex undertaking. Modern simulation methods allow you to factor in thermal and mechanical effects in addition to electromagnetics in the initial concept phase. In this course, you will go step by step into the conceptual design of an electric machine using Motor-CAD. You will learn the methods for simulating the individual physical domains and their possible applications. You will also calculate common characteristic curves and maps, as well as the multiphysics motor behavior during a driving cycle. Another focus of the training is the automation of workflows by coupling Motor-CAD with the optimization solver optiSLang.
The training course is aimed at all engineers and designers involved in the development of electric machines or anyone interested in the design and reliable operation of electric machines. Simulation knowledge is not necessary.
After attending this course, you will be able to use Motor-CAD to calculate and evaluate various parameters for electric machines. You will be able to quickly determine maximum torque and continuous torque characteristics, the efficiency map and drive cycles. Automated workflows help you to efficiently optimize motor designs.

For more information on the validity and how booking with the code ACADEMIC50 works, please visit our page on training for academic users.
Straight after you sign up, an automatic confirmation of receipt will be sent to the email addresses you provided. Once you have successfully verified the data you provided, you will receive your personalized sign-up confirmation, containing further information on course fees, the billing address, etc., by email within two to three working days.
As soon as the minimum number of attendees has been reached, you will receive a final training confirmation containing further information on how to get to the venue. We recommend that you wait until you have received this final confirmation before booking your travel and accommodation.
If the minimum number of attendees is not reached, we reserve the right to cancel the training seven days before it is due to start at the latest. We are happy to help you change your booking to an alternative date. Please note that we accept no liability for hotel or travel bookings that attendees have already made.
Usually the training courses start at 9:00 am and end at 5:00 pm of the respective local time. The actual course times will be stated in the booking confirmation. Please note that, depending on the training host, there may be a possible time shift between your and the provider's local time. Therefore all local times are provided with the valid time shift to Greenwich Mean Time (GMT).
To get a clear impression of our online learning format, we offer you a trial allowing you access to the starting module of an eLearning course of your choice. No costs, no cancellation period or anything similar. Moreover, with this free test access you can check all the technical requirements for a smooth learning process. You can easily request the free module from any eLearning course.
Each online course day comprises four eLearning modules. You should ideally allow 90 to 120 minutes of uninterrupted learning time for each module. This will allow you to acquire the knowledge provided by a module and to consolidate it through quiz questions and Ansys exercises. By dividing each module into micro learning units, you can also make good use of smaller time windows, such as on your commute.
Prerequisite for the use of the eLearning courses is the use of a personal access to the CADFEM learning platform.
Upon purchase, the duration of use of your eLearning course is 12 months. After expiration of the usage period you have access to your completed eLearning course for another 12 months.
As a user of a learning subscription plan, the duration of use of your flat rate is 12 months. After this period of use has expired, you will have access to your completed eLearning course for a further 12 months.

This is how modern training works in the home office era! CADFEM eLearning comprehensively covers the possibilities of Ansys Motor-CAD. The flexible time allocation of the teaching units offers opportunities to independently go on a journey of discovery with the knowledge gained. This is my clear recommendation for all those who are interested in engine design.
The right training, hardware and additional software products are the keys to success when it comes to a quick introduction to simulation.
