Motor Design Ltd: An Ansys Company

Motor-CAD is linked to Maxwell to perform detailed design and validation after the initial design. Maxwell can execute rigorous 2D and 3D performance calculations of the machine, including the motion-induced physics caused by linear translational and rotational motion, advanced hysteresis analysis, demagnetization of permanent magnets and other critical electromagnetic machine parameters.

Maxwell is integrated into Ansys Electronics Desktop, where it can share the same CAD source and can be coupled to Ansys Mechanical, Ansys Fluent or Ansys Icepak. Mechanical’s stress, thermal, CFD and acoustic solvers provide important multiphysics capabilities required for a detailed analysis of the electric machine. Losses calculated by Maxwell can be used as inputs to the thermal or CFD solver to calculate the temperature distribution of the machine and evaluate cooling strategies.

Electromagnetic forces and torque calculated in Maxwell are used as inputs to the stress solver to analyze deformations and further assess potential vibrations. The ability to perform an in depth multiphysics analysis with Ansys’ powerful solvers truly sets the Ansys Motor-CAD apart from the competition.
