Abstract
An electromagnetic energy converter for a remote switch. The energy converter has an electrical coil and magnetic components, which comprise at least one permanent magnet and at least one ferromagnetic element. The permanent magnet and/or the ferromagnetic element are each movable between two extreme positions, where the movement of the permanent magnet and/or of the ferromagnetic element between the extreme positions leads to a directional reversal of a magnetic flux in the magnetic circuit. The magnetic flux is enclosed at least in part by the coil. At least one of the extreme positions is configured as a contactless extreme position at which at least two of the magnet components do not contact.
Claims19
An electromagnetic energy converter for a remote switch, comprising:
- magnetic components for generating a magnetic circuit having a magnetic flux, the magnetic components comprising at least one permanently magnetized arrangement having a permanent magnet, and at least one ferromagnetic element, the ferromagnetic element having a first portion and a second portion that is spaced away from the first portion, and
- wherein the energy converter further comprises at least one electrical coil at least partially enclosing the magnetic flux,
- wherein at least one of the permanently magnetized arrangement and the ferromagnetic element is movable relative to the other one between first and second extreme positions, wherein at the first extreme position, (i) the magnetic circuit is closed, (ii) the permanently magnetized arrangement contacts the first portion of the ferromagnetic element, and (iii) the permanently magnetized arrangement and the second portion of the ferromagnetic are not in contact and separated by a first gap having a first distance, and
- wherein at the second extreme position, (i) the magnetic circuit is closed, (ii) the permanently magnetized arrangement contacts the second portion of the ferromagnetic element, and (iii) the permanently magnetized arrangement and the first portion of the ferromagnetic are not in contact and separated by a second gap having a second distance;
- wherein the movement of the permanently magnetized arrangement and/or the ferromagnetic element between the first and second extreme positions results in a directional reversal of the magnetic flux in the magnetic circuit.
