  • Patent number: 11927264
    Abstract: A magnetic actuator includes a first element and a second element movable with respect to the first element in a movement direction. The first element includes teeth successively in the movement direction, two coils in slots defined by the teeth, and a permanent magnet. The second element includes teeth successively in the movement direction. The teeth of the first and second elements and the permanent magnet are arranged so that the second element is held by magnetic forces in each of three positions also when there are no currents in the coils. The second element can be moved between the three positions by supplying electric currents to the coils. Thus, the second element is held in any of the three positions also when current supply to the magnetic actuator is unintentionally lost.
