Electromagnetic Field Simulation

electromagnetic field simulation servicesSolenoid Systems uses ANSYS Maxwell, a state of the art and premium electromagnetic field simulation software for designing and analyzing 2-D and 3-D electromechanical devices, including Solenoids, Motors, Transformers, Sensors and Coils.  The Finite Element Analysis (FEA) solves static, frequency domain, and time varying electromagnetic fields.  The analysis produces the  magnetic characteristics (Flux (Φ),  Flux Density (B), Magnetic Field Strength (H), core losses, etc) and the Force or Torque output of the armature.

Beyond a static simulation, Solenoid Systems can perform a Dynamic Simulation, considering the full electrical and mechanical transients to determine the response time of a Solenoid, how fast the armature reaches the closed or open position.  This  type of Dynamic simulation can be performed using a a voltage source or a complicated external circuit, such as a custom Peak and Hold circuit.  Nonlinear materials and eddy currents are also factored into the Dynamic simulation as well as mechanical equations of motion, including damping, vibration and load forces,  all of which can be a function of position, speed or time.

The ability to couple electronic circuits and external loads to the electromagnet analysis allows Solenoid Systems to simulate the Solenoid as it functions in the application, creating and validating a virtual prototype that meets the customer’s specifications.  The virtual prototype is then ready for real prototypes to be manufactured with a high confidence of success, eliminating costly iterations.

Multi Physics Solution

Other Finite Element Analysis (FEA) tools such as Computational Fluid Dynamics (CFD), Mechanical and Thermal analysis can be coupled with the Electromagnetic analysis to provide a multi physics solution that simultaneously accounts for the multiple external physical forces such as fluid, thermal and mechanical forces which all impact the performance of the device.
