Motor CAD Software

Design Expertise

Motor Design Ltd (MDL) offer a wide range of consultancy services dedicated to electric machinery design for industrial companies operating in various application fields.

Our consultancy services are led by Dr Mircea Popescu who, during his almost 30 years in the engineering profession, brought original contributions to the analysis, optimal design theory as well as to the engineering development of high efficiency electric machines.

There are many ways in which MDL can help.

1. We provide complete original designs for electric motors and generators. The predicted electromagnetic and thermal performance of the new designs is presented in comprehensive and detailed reports. The analysis of the newly designed machines is based on our expertise together with a highly specialised software suite that includes: Motor-CAD, SPEED and ANSYS.

2. We optimise your existing electric machines designs and provide expert advice on how best to meet specifications such as size, weight considerations, energy efficiency or cost.

3. We investigate thermal problems in your existing electric machines design. Our expert knowledge of the cooling of electric machines, together with our cutting-edge thermal analysis tools, enable us to find solutions to a wide range of thermal problems.


Our services are based on your requirements and the action plan is drawn up in close consultation with clients to ensure that the service meets your needs. Where necessary, we will call upon the expertise of our professional partners in research and industry to widen our skills base.

We have worked on numerous projects for a wide range of clients in many different industries. Our projects have included hybrid/electric vehicles, green aircraft, wind power generation, submersible pumps, hermetic compressors, conveyer rollers and racing cars.

One thing all our customers have in common is the reassurance of knowing that their motor design issues will be dealt with by professionals who are skilled motor designers with extensive experience in this area of work.

Please contact us for more information about our consultancy services.


“The expertise provided by MDL was most valuable for our projects. We have used their detailed electromagnetic and thermal analysis capabilities for complex models, leading to developments of high performance electric machines.”

Dr Dan Ionel - FIEEE

Chief Engineer, Regal Beloit Corp., USA

“Equipmake has been working closely with Motor Design Ltd for over 2 years. MDL have provided us with state of the art design and analysis services, enabling us to successfully prototype new motor designs in record time.”

Ian Foley

Director, Equipmake, UK

“In recent years Motor Design Limited have provided the Denis Ferranti Group with a sound electromagnetic and thermal design service. Their reactivity and technical competence has to be commended.”

James de Ferranti

General Manager, Denis Ferranti Group, UK

“The guys at Motor Design have become a key part of our motor development and optimisation process. We can outsource tricky electromagnetic and thermal problems to them which they solve with a minimum of input from us. This means that we have been able to significantly reduce our product development times and still get great results.”

Steven Jennings

Department Manager Advanced Development, Interroll Research Centre, Germany

“Motor Design Ltd is a rare design resource for induction machines. Not only do they provide solid motor analysis, but they also communicate well across cultures and nationalities, making them a pleasure to work with. In the expanding world of induction motors, especially for electric vehicle traction, MDL get my recommendation.”

Malcolm Burwell

North American Technology Director, International Copper Association
