September 2017

  - New loss models from current IEC Standard 61800-9-2:2017 - Fully automated versions of:
  • Annex A: Losses from the defined Reference Power Drive System (A3 - RPDS)
  • Annex D: Standardized IE2 motors with added converter losses

- New loss model for standardized Converter Drive Module (CDM), in cooperation with Aalborg University
- New loss models for: Permanent Magnet motors, Synchronous Reluctance Motors, in cooperation with University of Gent
- New loss models for: Helical Gears, Helical-Bevel Gears & Helical-Worm Gears, in cooperation with University of Gent
- Updated & expanded scope for existing model for asynchronous motors + CDM:

  • Pre-selectable asynchronous motors of IE1, IE2, IE3 & IE4 efficiency class levels
  • Scope expanded to include asynchronous motors from 0.12 kW to 1.000 kW; 2, 4, 6 & 8 pole

- Updated application calculator – now includes:

  • Pump, Fan, Hydraulic pump, Air-compressor, Cooling-compressor
  • Language updates implemented – now includes:
  • Danish, English, German & French



January 2016


Date protection extended until 1 January 2018.



May 2014


Updated motor and variable speed drive models. New model for permanent magnet motors. Possibility for user-defined load, either as single duty point or complete load profile. Minor corrections. Expiry date: 1 January 2016.




January 2013


Internal corrections allowing the Motor Systems Tool to run in Asian countries.

(tested on Korean Windows)
