Permanent Magnet Simulation
Design and analyze permanent magnet assemblies, motors, and actuators.
This example models a Halbach-array planar actuator on an aluminum plate in EMAG, refines the mesh on magnets and plate, and computes vertical deflection that matches published reference results.
This note analyzes an axial flux permanent magnet coupling using 3D electromagnetic finite element simulation, with parametric studies on rotor load angle and air gap. Static torque and axial flux density are validated against analytical and experimental data to quantify pull-out torque and synchronous operation.
A radial double-sided permanent magnet eddy current coupler is analyzed with 3D transient finite element simulation to predict electromagnetic torque and eddy losses in a stainless-steel conducting sleeve. The study evaluates magnetic flux, eddy current distributions, torque versus time, and solid loss density, and compares average torque and loss values with analytical and experimental data.
The disk permanent magnet governor application note shows how EMWorks for Inventor is used to design and optimize a PM governor in 3D, evaluating torque, axial flux, eddy currents, and heat flux. Using coupled magnetostatic, transient magnetic, and thermal analyses, it helps engineers fine-tune magnet layout, air-gap, and disk geometry for stable speed regulation and higher efficiency.
