Additional information

The example contains:

  • relay.pro: 2D model of a linear actuator [1][2]. It comprises a yoke, two permanent magnets, two coils and a mover. The yoke and the mover are made of iron. Eddy currents in the magnets and in the laminated yoke and mover are neglected. The permanent magnets constitute a magnetic lock that keeps the mover either in the upper or lower position tending to diminish the residual airgap. The mover is moved down or up by applying a voltage pulse to one of the coils. The commutation is facilitated by two springs.
