Motor-CAD Software

About MDL

Motor Design Ltd (MDL) is a world leader in developing advanced software and tools for electric machine design. We have been developing electric motor design software since 1998.

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.

The design consulting services we offer cover all aspects of motor design from concept, performance optimisation, through to test and prototype development. Our customers benefit from our years of experience in designing electric motors and in-depth knowledge of simulation techniques.

Research and innovation is at the heart of what we do. We are active on several international research funded projects and have developed advanced motor solutions for the automotive and aerospace markets.


Dr David Staton’s PhD research studies at the University of Sheffield in the 1980s centred on the development of CAD software for electric machines.

In 1998, he became the founder of the pioneering company, Motor Design Limited, with the specific aim of developing Motor-CAD – the world’s first and only motor design software designed to simplify the complexities of thermal analysis. Since then the software has developed significantly.

Dave Staton is an expert in the thermal analysis of electric motors and has published well over 100 technical papers and books. He presents tutorials at electrical machine design conferences worldwide.

MDL’s main offices are in the UK. The company also operates a worldwide distribution network.

MDL’s highly experienced team of global distributors have been successfully marketing Motor-CAD software for fifteen years.


Green Technology


Motor Design Limited (MDL) is completely committed to supporting emerging green technology and renewable energy.

The software is already helping to drive the green revolution and the viability of renewable energy. It is used by electric vehicle and aircraft manufacturers to optimise the size of motors and reduce CO2 emissions. MDL’s product is also used to ensure that green alternatives, such as wind generators, have the correct cooling.

In partnership with the University of Bristol and Adapted Solutions, MDL are part of the EU’s Clean Skies Joint Technology Initiative. MDL is developing thermal models for novel motor and generator topologies to aid the design of a new Helicopter Electric Regenerative Rotor Brake (HERRB) for AgustaWestland Helicopters. MDL’s expertise enables the development of reliable models that can work with other models to ensure reliable system simulation leading to optimum design.

ELETAD is another partnership project, this time with the Universities of Bristol and Bucharest and Lucchi Rimini Elettromecanica. MDL is contributing to the development and build of a prototype electric tail rotor for AgustaWestland Helicopters. This is another Clean Sky Joint Technology Initiative funded by the EU.

MDL is helping to bring green energy to households in the UK and Ireland. Our experts are providing the expertise to support the design and manufacture of a state-of-the-art series of wind turbines. These are equipped with direct driven permanent magnet machines and cover a power range from 6kW to 100kW.
