Analysis

Analysis

SDT offers clients many kinds of analyses for electrical machines, including:

  • Rapid performance analysis for feasibility or initial design.
  • 2D finite element modelling for design validation and calculation of electromagnetic phenomena such as eddy current losses, unbalanced magnetic pull, iron losses, cogging and ripple torques, inductance and back-emf.
  • 3D finite element modelling when end effects are significant, for instance with 'pancake' type motors.
  • Thermal analysis using rapid-analysis software and thermal finite element modelling.
  • Mechanical aspects including interference fits and critical speeds

The specification ensures that all aspects of a machine’s performance and installation have been clearly defined before valuable time is spent on the remaining stages. Packaging work is normally undertaken using 3D CAD software.
