Additional information
The example contains:
- relay.pro: 2D model of a linear actuator. 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. [1]
