Latest software release – Motor-CAD v12


Motor Design Ltd is delighted to announce the release of Motor-CAD v12 — the latest version of our unique software package dedicated to the electromechanical performance of motors and generators and the optimisation of their cooling.


About Motor-CAD

Motor-CAD software enables motor designers to evaluate motor topologies and concepts across the full operating range and produce designs that are optimised for performance, efficiency, size and cost. The software’s four integrated modules—EMag, Therm, Lab and Mech—allow multi-physics calculations to be performed quickly and iteratively, so users can get from concept to final design in less time.

  • EMag: Uses a combination of 2D FE environment and analytical algorithms for fast calculation of electromagnetic performance. Optimise designs easily with our extensive range of parameterised templates and geometries.
  • Therm: The industry-standard tool for thermal analysis of electric machines, with over 20 years of inbuilt experience. Calculate the temperature of the motor components in steady-state and transient operating conditions and accurately model thermal behaviour within seconds of calculation.
  • Lab: Enables rapid and accurate analysis of any electric machine design over the full operating envelope. Carry out efficiency mapping and drive cycle analysis within minutes.
  • Mech: 2D FEA based solution in Motor-CAD to analyse stress and displacement in rotors during operation (new in Motor-CAD v12).

Accurate electromagnetic and thermal calculations can be performed in minutes, allowing users to respond to changing specifications, innovate and explore the whole design space.

Download the latest agenda here – Motor-CAD European User Conference 2019 Agenda


Workshop 1 – Advanced Electromagnetic Loss Modelling in Electric Machines

Presented by: Dr Mircea Popescu (Chief Technology Officer, MDL), Ben Silvester (PhD Research Student, Warwick Manufacturing Group) and Dr Giuseppe Volpe (Senior eMachine Specialist, MDL)

This workshop will look into detail about the various loss components in electric machines. Complex and difficult to estimate losses—such as core losses under non-sinusoidal supply, AC losses in windings, electrical conducting regions (magnets, solid iron rotors, retaining sleeves) losses—will be investigated for various motor types and applications. The methods and approaches used in Motor-CAD to compute these various loss components will be discussed and the calculations behind the analysis will be explained. The trade-off in accuracy vs computation time between full 3D FEA and hybrid 2D FEA and analytical algorithms will be illustrated. The manufacturing effects and variation of the various loss components will also be covered in detail.

Who should attend? This workshop is intended for experienced Motor-CAD users who would like to learn more about the methods used to calculate and analyse losses.


Workshop 2 – Optimisation Solutions for Electric Machine Design

Presented by: Dr Stjepan Stipetic (Assistant Professor, University of Zagreb), Markus Stokmaier (Dynardo), Dr James Goss (Chief Executive Officer, MDL) and Nicolas Riviere (Research Engineer, MDL)

This workshop will be run by Stjepan Stipetic from the University of Zagreb and Markus Stokmaier from Dynardo. The workshop will introduce the theory behind optimisation of electric machines and will present two optimisation solutions using either the Motor-OPT or OptiSLang tool coupled to Motor-CAD.


Workshop 3 – Combined Motor-CAD and ANSYS Workflow

Presented by: Lester Gomez (CADFEM GmbH), Akeel Auckloo (ANSYS) and Giulia Malinverno (Research Engineer, MDL)

This workshop will introduce the combined Motor-CAD and ANSYS workflow and will demonstrate the automated links between Motor-CAD and the ANSYS tools such as Maxwell, Simplorer, Mechanical, Fluent and ICEPack. The workshop will present a detailed example of the calculation and extraction of magnetic forces in Motor-CAD for motor vibration analysis in ANSYS Mechanical. The workshop will conclude with a presentation of the future roadmap for further coupling between Motor-CAD and ANSYS tools.


Workshop 4 – Advanced Lumped Parameter Thermal Modelling Techniques

Presented by: Dr Eddie Chong (Lead Thermal Specialist, MDL), Husain Adam (Software Developer, MDL) and YaoHui Gai (Senior E-Machine Specialist, MDL)

This workshop will look at how Motor-CAD Thermal can be used effectively in the design process. It will show attendees how to model complex cooling methods and to account for some of the more difficult aspects of thermal behaviour. It will then look at a case study in which a Motor-CAD model is generated, compared and calibrated against experimental test data from oil spray and oil dripping cooling methods. The workshop will also cover how Motor-CAD can work alongside CFD tools extracting the convective heat transfer coefficient for rotor shaft hole cooling and how the lumped parameter thermal model can be used in a system simulation.

Who should attend? This workshop is intended for experienced Motor-CAD users who would like to learn more about the thermal analysis aspects of Motor-CAD and how to effectively integrate it into their design process.

Workshop on ‘Design Trends and Performance Analysis of BEV & HEV Electric Machines’ at Motor & Drive Systems 2019

Dr. David Staton will be running a workshop on ‘Design Trends and Performance Analysis of BEV & HEV Electric Machines’ at the 2019 Motor & Drive Systems Conference in Orlando, Florida.

Workshop Overview

Dr. David Staton, President and Founder of MDL

There are a wide variety of new electric machine designs being developed for use in battery electric vehicles (BEV) and hybrid electric vehicles. Different motor types are available such as brushless permanent magnet (BPM), induction, switched & synchronous reluctance and wound field synchronous machines. The BPM is available with radial or axial fields. The most popular motor type used in the current range of BEV and HEV is the radial airgap BPM motor with an interior permanent magnet (IPM) structure. The range of IPM topologies available to the designer is large with different numbers and position of the flux barriers and magnets. Nd-Fe-B is the predominant magnet type but is quite expensive due to the use of rare earth materials. There is some research into the use of cheaper ferrite magnets.

Various winding techniques are used such as distributed random wound and precision or bobbin tooth wound windings. There is also a current trend to use hairpin windings. Various cooling types are available such as the use of stator water jacket of various design, oil spray cooling of the end windings, passing oil through the windings, a rotational water jacket on the shaft, potted end windings, etc. New materials are also being developed to improve the magnetic and thermal properties of the machine design.

The workshop will include:

  • Show the results of teardown studies on various existing machines from such vehicles as the Nissan LEAF, Tesla Model S, Toyota Prius, BPM i3, Honda Accord, etc.
  • Demonstrate how reverse engineering benefits from electromagnetic and thermal simulation to gain a full understanding of a teardown motors performance.
  • Show models developed in Motor-CAD predicting the performance of a range of existing BEV traction motors.
  • Performance data calculated includes peak and continuous torque/speed envelopes, efficiency and loss maps, optimum field weakening angle maps and drive cycle analysis with predictions of motor temperature vs time.
  • BPM, induction, switched & synchronous and wound field synchronous machine designs will be shown with a wide variety of cooling types, winding types and materials.
  • Comparisons of model data with test data.
  • Show initial results from some new research projects to develop BEV electric machines with higher performance and lower cost than existing state of the art machines.

Watch our webinar on ‘Accounting for AC Winding Losses in the Electric Machine Design Process using Motor-CAD’

Webinar presenters: Dr. James Goss (CEO) and Dr. Mircea Popescu (Chief Technology Officer)

The efficiency and power output capability of an electric machine is defined by the losses generated during the machine operation. Losses that are generated in a machine cause heating, which fundamentally limits performance and defines the maximum torque and power capability of a design. Taking machine losses into account early on in the design process is, therefore, crucial to ensure that the design requirements are met.

Watch this recording of our recent webinar to learn how to accurately and effectively model AC winding losses in your electric machine designs from the early stages of the design process, with live demonstrations in Motor-CAD.


This webinar covers:

– Multiphysics electric machine analysis using Motor-CAD
– Theory on AC winding losses
– Modelling approaches for calculating AC winding losses
– Accounting unevenly distributed AC winding losses in a lumped parameter thermal model
– Demonstration of modelling AC winding losses electromagnetically and thermally using Motor-CAD.

What will you learn?

– How to accurately and effectively model AC winding losses in your electric machine designs from the early stages of the design process
– How to mitigate AC winding losses in your electric machines.

Who is this webinar for?

– Engineers and technical professionals working in the electric machine design industry.
