Reed Switch under the influence of the magnetic field produced by a coil.
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.
- Induction Motors:
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.
Simulations using INTEGRATED software permit determination of armature forces and/or torques as well as equivalent circuit parameters.
