Magnetic Field Analysis is at the heart of many sensor systems, particularly systems with large air gaps.
These applications can be easily modeled using MAGNETO (if 2D or Rotational Symmetric) or AMPERES (where full 3D analysis is required).Both programs provide a complete range of analysis options including field plots, flux linkage and inductance calculations. Force, torque, power loss and stored energy can also be calculated.
In the case of LVDT sensors, Usually OERSTED (2D/RS) or FARADAY (3D Simulation) will be required because of eddy currents induced in the sensor components. If the sensor is composed of ferrite and/or laminated materials, MAGNETO (2D/RS) or AMPERES (3D Simulation) should be sufficient
