FEA & SIMULATIONS

FEA & Simulations
FEA and simulations are the first step, and saves time, money, and design work when all components and magnetics are viewed through the results of advanced software and the knowledge of experienced magnetics engineers.

Past Engineering Projects & Products
Find examples below of the projects and products that the SM Magnetics Engineers have worked on with our customers during the design phase. Our Finite Element Analysis and magnetic simulation shortened the design process considerably.

• Determined the holding force between a charging unit and wearable device for a large consumer electronics company to ensure a positive customer user experience.
• Simulated the moment a Reed Switch was triggered by a passing neodymium magnet in a medical device that is used during surgery in the body.
• Determined the gauss level at 2.5mm from a neodymium magnet to a PCB in a low speed motor to understand the effect of the magnetic field on the PCB.
• Redesigned the stator of a LiDAR motor to achieve the correct start-up torque and RPM of a brushless DC motor.
• Determined the pull / hold force of a 4” magnetic assembly in a marine application that was attaching to 1” thick steel in extreme weather conditions.
