MotorSolve Thermal | Features

MotorSolve Thermal is a 3D FEA-based analysis tool. It offers seamless co-simulation between electromagnetics and thermal physics for machine designers, all within a single interface. Multiple design scenarios can be setup, solved and post-processed in a single model file.

  • Calculate the steady-state temperatures using the losses from the magnetic analysis
  • Perform the magnetic analyses at these steady-state temperatures taking into account the change in material properties due to the change in temperatures
  • Automatic calculation of the heat transfer coefficients
  • User controlled over-ride of heat transfer coefficients
  • Steady State experimental conditions
  • Duty Cycle transient experimental conditions
