Advanced Electric Machine Design with Electromagnetic and CFD Simulations

You may have read a quick blog post at Desktop Engineering about ANSYS’s electric machine simulation capabilities. Here we dive into the technical aspects and implications of thermal simulation for electric machines.

Electric machine geometry with cooling and integrated power electronics.

Electric machine geometry with cooling and integrated power electronics.

Modern electric machines are designed to meet a wide range of applications, all facing a variety of different technical challenges. They are designed to be compact with high power densities, to have integrated power electronics, to be high-speed for higher power density, and to handle harsh environments.

These challenges all have thermal implications that affect the lifetime and performance of the electric machine and power electronics, and must be balanced with cost goals. ANSYS simulation tools, Fluent and Maxwell, can be used to predict the thermal and electromagnetic performance of these systems, and can therefore be used to optimize design choices for both thermal and cost considerations while meeting all application objectives.
