Welcome to Emetor, the online electric motor design software

Emetor is an online software for the design and dimensioning of electrical machines. With Emetor you get all the tools to improve the performance of your electric motor designs. Products from Emetor are today used both in industries, for example at Atlas Copco Tools, as well as at leading universities, such as the Royal Institute of Technology in Stockholm. We are convinced that the electric motor design software Emetor is also a competitive solution for you and your organization.

Emetor preprocessor

1. Choose a machine template and provide parameters

  • Inner-rotor or outer-rotor surface-mounted permanent magnet machines.
  • Radially-magnetized, parallel-magnetized, or breadloaf permanent magnets.
  • Stators with parallel teeth, parallel slots, or user defined shapes. Slotless stators are also possible.
  • Glossary link about most template parameters, with advice on what to consider when choosing the parameter values.
  • Preview of the geometry cross-section.
  • Ready to simulate example machines with literature references.

Emetor winding calculator

2. Choose a suitable winding layout

  • Fast and convenient way to find the optimum winding layout for your electric motor design.
  • Investigate integer-slot, fractional-slot and concentrated windings, all with single and double layers.
  • Compare the maximum fundamental winding factor for different combinations of number of poles and number of slots.
  • Display and compare the winding layout for different coil spans.
  • Display and compare the harmonic spectrum of the winding factor for different electric motor windings.

Release 2012-01-26: All registered users can run simulations (Jan 26)
After successful beta testing, it is now possible for all registered Emetor users to setup, run and analyze their own electrical machine simulations.
Rule of thumb for calculating stacking factor as a function of lamination thickness (Jan 19)
Not many producers of electrical steel do provide the stacking factor for their lamination sheets. This is fully understandable since the stacking factor depends a lot on the manufacturing process, i.e. the punching and stacking of the lamination sheets. Still, the rule of thumb for calculating the stacking factor as a function of the lamination thickness presented in this blog post might be a valuable first estimate for any electrical machine designer.
How to calculate the torque of an electrical machine? (Jan 10)
This blog post discusses advantages and drawbacks of different methods suitable for calculating the torque of an electrical machine. It mainly focuses on the Maxwell's stress tensor, which is the method used to calculate the torque in the online electric machine design software Emetor.
2011 Emetor user statistics (Jan 03)
2011 has been a fantastic year for Emetor with more and more visitors finding and experiencing the advantages of our online electric motor design software. We would like to thank all our dedicated users and wish you a successful new year 2012.
Development status Christmas 2011 (Dec 23)
It has been a busy fall for Emetor this year with several consultancy jobs both here in Sweden and in the UK. In addition, the development of the online electric machine design software Emetor has progressed and beta testing has successfully started some weeks ago. In this blog post I will give you an overview of the development status of Emetor, including some promissing preview images. And last but not least: Have a marry Christmas and a happy new year!
