Simulation helps to accelerate the development of electric motors considerably

Simulation makes electric motors more competitive

Multiphysics challenges as well as cost and time pressure determine the development of electric motors. State-of-the-art simulation methods can help.

The perfect workflow

Nowadays, the efficient development of electric motors and generators without using a simulation aid is inconceivable. The optimal variant depends on so many parameters that field tests and prototypes are uneconomical and too tedious in the long run.

The electric motor challenge

Modern specifications require increasingly detailed information in the early phases of the development process, including in areas such as:

  • Electromagnetic fields, among other things with torque, torque ripple, and cogging torque, as well as excitation forces.
  • Thermal management with temperature distribution – in some cases, this is critical to demagnetization.
  • Active cooling with different fluids for better motor utilization.
  • Mechanical loads, especially with delicate IPM structures.
  • Acoustic requirements – since the combustion engine is missing, which drowns out all electric motors.
  • System simulation, with battery and converter.

The time factor

One solution is simulation software. The factor of time also plays a part in electric motor simulation, if only traditional tools are used. The many variants and challenging disciplines such as thermal dynamics, structural mechanics, electrotechnics, and acoustics take their toll on computing power and interaction intervals.

Quick preselection

British software developer Motor Design Limited (MDL) has launched a solver package specially developed for the electric motor industry – Motor-CAD – which enables quick simulation during operation of key areas such as electromagnetics (EMag), thermal dynamics (Therm), structural mechanics (Mech), and efficiency.

Optimized workflow

CADFEM has identified the benefits for its clients and has cleverly combined Motor-CAD with ANSYS for detailed analysis, creating the ideal tool combination for an improved workflow for virtual electric motor development:

  • Quick iterations and variant checks in Motor-CAD
  • More in-depth analysis of favorites in ANSYS Workbench
  • Virtual commissioning at system level in ANSYS Twin Builder
  • Early launch of optimal electric motors to the market
