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 as well.

Supported Machine Types

• All templates in MotorSolve BLDC
• All templates in MotorSolve IM

MotorSolve Thermal is an optional module which requires at least one electromagnetic analysis module. To learn more about the templates, design parameters, windings, results and other electromagnetic related topics for machines, please visit the MotorSolve BDLC or MotorSolve IM web pages.

Rapid and Accurate Results

MotorSolve offers two-way coupling within one software package without the need to link two separate tools or burdensome problem setup:

• 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

Output Waveforms and Charts

• Losses for thermal analysis
• Temperatures for magnetic analysis
• Temperature (max, min, avg) by component (winding, bearings, magnets, etc..)
• Duty cycle losses
• Heat capacity
• Heat flux

 

Export
