Relays and Contactors

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.
