Control of component and system temperatures remains one of the most significant challenges in the design of electronic systems because excessive thermal loading limits the maximum performance of an electronic device or an electric machine and significantly increases the energy footprint of the system. The simple truth is that, in an increasingly competitive market place, simulation can provide the necessary insight into the performance of a new device. Deploying CFD in the early stages of the design process avoids expensive redesigns as the machine nears production and ensures that optimal designs are chosen.
STAR-CCM+ in combination with SPEED is an integrated toolset for virtual prototyping of electric machines and delivers the power of a very efficient design of the machine with integrated electromagnetic, fluid dynamics and heat transfer simulation technology:
SPEED has been in the business of electric machine designs for a quarter of a century and and has been successfully used in the design of thousands of products. Based on a deep underlying theory of the electric machine, it calculates almost all aspects of design in an efficient way. In addition, because of its speed of execution, there is no waiting time for the designer, a critical requirement in assuring design productivity. SPEED is also capable of contributing geometry and heat loads to STAR-CCM+ allowing for a full flow and thermal analysis of the electrical machine.
STAR-CCM+ has a solver for Magnetic Vector Potential, which operates in stationary and transient mode and couples to electrical potential solver for electromagnetic problems.This capability, when coupled with the existing models - namely fluid flow, heat transfer and structural mechanics - enables the electromechanical, thermal and structural analyses to be carried out from the same model. This allows simulation engineers to accurately visualize the performance of electric machines at the edge of their operating envelopes.
