Abstract
When servomotors are made more compact, thermal problem becomes dominant. Nowadays, the combined effect of heatsink and epoxy potting dissipates almost half of the total loss and brings more attention to end-region´s thermal design and analysis. This paper presents three market-existing end-region models and compares their thermal performance using thermal network. Results have good agreement with those of computable fluid dynamics (CFD) and show that model 3 is preferred because of lowest temperature rise.
