Abstract
Magnet assemblies of electromechanical assemblies for elevator systems are described. The magnet assemblies include a magnet, at least one rail engagement block, and an encapsulating body encapsulating the magnet and the at least one rail engagement block, wherein the encapsulating body is formed from a non-magnetic material. A target extension is formed from the material of the encapsulating body and extends away from the magnet and the at least one rail engagement block. A proximity switch target is held within the target extension for detection by a proximity switch.
Claims20
A magnet assembly of an electromechanical assembly for an elevator system, the magnet assembly comprising:
- a magnet;
- at least one rail engagement block;
- an encapsulating body encapsulating the magnet and the at least one rail engagement block, wherein the encapsulating body is formed from a non-magnetic material;
- a target extension formed from the material of the encapsulating body and extending away from the magnet and the at least one rail engagement block;
- and
- a proximity switch target held within the target extension.
An electromechanical actuator of an elevator system, the electromechanical actuator comprising:
- a housing;
- an electromagnet assembly moveably mounted within the housing;
- and
- a magnet assembly moveably mounted within the housing and configured to magnetically engage and disengage from the electromagnet assembly;
- wherein the magnet assembly comprises:
- a magnet;
- at least one rail engagement block;
- an encapsulating body encapsulating the magnet and the at least one rail engagement block, wherein the encapsulating body is formed from a non-magnetic material;
- a target extension formed from the material of the encapsulating body and extending away from the magnet and the at least one rail engagement block;
- and
- a proximity switch target held within the target extension.
