Simulation of Electric Machines

In 2017 Motor Design Ltd (MDL) and CADFEM have announced their close partnership.

The two companies share a passion for Simulation Driven Product Development and a commitment to the notion that Simulation is More than Software. The combination of software [Motor-CAD and ANSYS] and expert services provided by MDL and CADFEM allow our customers to develop better machines in less time.

MDL is a world leader in developing advanced software and tools for designing electrical machines. Our software, Motor-CAD, is recognised worldwide as class-leading motor design software. We use our expert knowledge of designing electric motors to provide software support to electric machine designers at some of the most prestigious aerospace, automotive and industrial companies worldwide.

CADFEM is one of the largest European suppliers of Computer Aided Engineering (CAE) and is the ANSYS Channel Partner in several countries including the UK, Ireland, Germany, Austria, Switzerland, India. We are experts in simulation across all physics – mechanics, fluids, electromagnetics, systems… We sell and support the full ANSYS portfolio and help our customers to exploit the full benefits of simulation in their product development.

Motor-CAD can be used to quickly and easily perform electromagnetic and thermal performance tests on electric motor designs. ANSYS can be used to bring calculations of electromagnetic performance and cooling to the next level of accuracy and to predict and minimise noise and vibration.

We look forward to presenting to you how the two powerful tools can be integrated seamlessly within the ANSYS Workbench Environment.

MDL and CADFEM:

Motor-CAD, key capabilities:

  • EMAG: a fast 2D finite element module for accurate electromagnetic and electrical performance predictions
  • THERMAL: Combines a lumped circuit and finite element thermal calculation for optimising the cooling system of a machine.
  • LAB:Provides efficiency mapping and duty cycle / drive cycle transient outputs within minutes 

ANSYS, key capabilities for motor design & development:

  • Vibration and Noise prediction using ANSYS Mechanical
  • Evaluation of Improved Cooling Concepts with ANSYS CFD
  • Detailed magnetic loss and performance calculations with ANSYS Maxwell

Integration of Motor-CAD and ANSYS

  • Motor Design Geometry
  • Integration with ANSYS Mechanical, CFD, Maxwell

Head Impacts in Sports. Research Update: Impact Measurements using a Mouthguard

At the 8th World Congress of Biomechanics, Institute of Technology Tallaght and CADFEM welcomed colleagues from Stanford University at our exhibition stand.

We are delighted to report that the research project has evolved further to include head impact measurements using an instrumented mouthguard. Camlab at Stanford University is supplying the mouthguard technology. Measurements and simulations are performed by IT Tallaght. CADFEM Ireland provide ANSYS LS-DYNA and Cloud Computing power for the simulation and analysis work and to process the huge amount of data generated. The project also counts on St James’s Hospital Dublin for medical assessment and diagnosis, and Trinity College Dublin who are investigating the blood brain barrier using contrast MRI scans of participants.

Please stay tuned to our website and conference announcements, an update of the project will be presented at the 5th Simulation Conference, 1-2 November 2018, Engineers Ireland, Dublin. Contact us for immediate updates: info@cadfemireland.com

The World Congress of Biomechanics is the premier meeting worldwide in its field. Many of the main international biomechanics societies will fold their 2018 annual meetings into the 2018 World Congress, hence you can expect to meet many of your colleagues in Dublin.

CADFEM have extensive experiences in biomedical simulation. Our engineers and expertise have supported many world-leading bio-medical companies, as well as academic and medical institutions since 1998. Please meet us in the exhibition at the CADFEM booth, no 21. 

We are very pleased to recommend the poster presentation by Institute of Technology Tallaght Dublin, our partners, on 10th July. Please meet us at The Forum, Ground Floor.

CADFEM Group and Institute of Technology Tallaght and at the 8th World Congress of Biomechanics, 8th-12th July 2018, Dublin Convention Centre.

The Congress welcomed an international audience. We had the pleasure to meet delegates from Ireland, Germany, the UK, the USA, France, Italy, Turkey, Poland, Asia at our exhibition booth.

IT Tallaght presented the latest developments of the Research Project in the Poster Presentation: Investigation of the relationship between impact direction and principal strain within the brain on 10th July 2018.

 Presenter: Stephen Tiernan. Institute of Technology Tallaght Dublin. Authors: Stephen Tiernan, Gary Byrne, Derek Sweeney, Michael Power
Session: Head impact biomechanics and head protection Tuesday, 10th July. The Forum, Ground Floor.
