ELECTRIC MACHINES

MAIN FEATURES

  • Selection of an unlimited number of electric machines for each analysis
  • Description of each electric machine through data supplied from manufacturers (e.g. number of pole pairs, resistance, inductance, nominal values at best efficiency point, etc.)
  • Definition of non-dimensional quantities (frequency, voltage, current, power factor, electrical power, torque, rotational speed, mechanical power, etc.)
  • Definition of non-dimensional relationships based on similarity laws
  • Computation of non-dimensional characteristic curves for the full range of operation (i.e. motor & generator) using basic analytical techniques
  • Comparison of analytical functions with original data from manufacturers (e.g. torque versus rotational speed, power versus rotational speed, etc.)
  • Visualisation of results
  • Suitable for designing and testing

OPTIONS FOR IO OPERATIONS

  • Microsoft Excel Spreadsheet Files (xlsx)

OPTIONS FOR GRAPHICS

  • Standard Image Formats (jpeg, tiff)
  • Portable Document Format (pdf)

TEST CASES
