Motor CAD Software

Motor-CAD Lab

MDL’s unique combined electromagnetic and thermal modelling tool is the first of its kind in the marketplace; no other modelling tool offers equivalent functionality. Motor-CAD Lab was developed with a number of partners to enable rapid and accurate modelling of any machine over the entire operational envelope. It is specifically designed to aid the design of motors for traction applications.

Motor-CAD EMag modules are available for the following motor types:

  • Brushless Permanent Magnet motors (BPM)
  • Induction motors (IM)
  • Synchronous Reluctance motors (SYNCREL)
  • Synchronous machines (SYNC)

With Lab, engineers can create efficiency maps, plot torque/speed characteristics, study the continuous and peak thermally constrained operational envelope and analyse performance over driving cycles. It is fast, easy to use and the techniques have been experimentally verified.

Motor-CAD Lab has an intuitive user interface: data is produced in a simple format that can easily be exported to Matlab, Microsoft Excel and other applications. A wide variety of graphs can be generated and a number of publication-quality output formats are supported.
