For design analysis purposes, relays and contactors can be separated into two categories:
DC Relays and Contactors: Typically AMPERES (3D simulation) will be required. MAGNETO (2D/RS) may be used if rotational symmetry is present.
AC Shaded Pole Relays and Contactors: Since the force produced by the shaded pole is due to induced eddy currents, a time harmonic analysis is required. Typically FARADAY (3D simulation) will be required. OERSTED (2D/RS) may be used if rotational symmetry is present.
Simulation design using INTEGRATED software permits determination of armature forces and/or torques as well as equivalent circuit parameters.
