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.

The synchronous reluctance motor - a revolutionary world-class motor? (Apr 13)
Higher efficiency requirements and rare and expensive permanent magnet materials make synchronous reluctance motors an interesting alternative to conventional induction motors. With this background, ABB has recently launched their SynRM motor and drive package.
Modeling a stack of laminations in the finite element method (Mar 23)
In this blog post, it is explained how the iron core of an electrical machine consisting of stacked laminations can be modeled in the finite element method (FEM). The method is equally applicable for 2D- and 3D-FEM and is used in the electric motor design software Emetor.
Release 2012-03-23: Stacking factor is now considered (Mar 23)
If the iron core of an electrical machine is made of stacked laminations, this can have a major influence on the machine performance, especially if the lamination thickness is very thin. Now, the effect of the stacking factor is included in the online electric motor design software Emetor.
Overview of electric motor design softwares (Feb 14)
Are you looking for an electric motor design software? In this blog post, you can find a comprehensive list of motor design tools including links to the corresponding web sites. A short description of the type of software and its strength and features hopefully facilitates the choice of electric motor design software that is most suitable for your specific needs.
