Title: Automated recovery of rare earth permanent magnets from electric machines

Abstract

A method for the automated recovery of rare earth permanent magnets from electric machines are provided. The method includes identifying electric machines in a mixed product stream for performing a unique robotic disassembly routine. Electric machines that are not identified are diverted to a robot training station, during which time the system and the method include implementing a suitable disassembly routine. A conveyor delivers the remaining electric machines to a rotary platform having multiple stations for the simultaneous disassembly of multiple electric machines. Permanent magnets are removed from the electric machines and are then sorted for recycling operations.

Machines utilizing heavy rare earth free permanent magnets

Patent Islam, Md. Sariful; Husain, Iqbal

Various examples are provided related to machines utilizing heavy rare earth (HRE) free permanent magnets. In one example, a rotor assembly including a rotor core having a plurality of rotor slots and magnets positioned within the plurality of rotor slots. At least a portion of the magnets are free of heavy rare earth (HRE) elements. The magnets can include a combination HRE segments and HRE-free segments or can be free of HRE elements. The rotor assembly can be included in an electric machine such as, e.g., a permanent magnet (PM) machine.

Method for providing slip energy control in permanent magnet electrical machines

Patent Hsu, John S.

An electric machine (40) has a stator (43), a permanent magnet rotor (38) with permanent magnets (39) and a magnetic coupling uncluttered rotor (46) for inducing a slip energy current in secondary coils (47). A dc flux can be produced in the uncluttered rotor when the secondary coils are fed with dc currents. The magnetic coupling uncluttered rotor (46) has magnetic brushes (A, B, C, D) which couple flux in through the rotor (46) to the secondary coils (47c, 47d) without inducing a current in the rotor (46) and without coupling a stator rotational energy component to the secondary coilsmore » « less

Acid digestion processes for recovery of rare earth elements from coal and coal byproducts

Patent Peterson, Rick; Heinrichs, Michael; Gadkari, Vinay V.; ...

A system for recovering rare earth elements from coal ash includes a leaching reactor, an ash dryer downstream of the leaching reactor, and a roaster downstream of the ash dryer that is cooperatively connected to both the leaching reactor and the ash dryer. Coal ash is mixed with an acid stream such that rare earth elements present in the coal ash are dissolved in the acid stream, thereby creating (i) a leachate containing the rare earth elements and (ii) leached ash. The leachate is heated to obtain acid vapor and an acid-soluble rare earth concentrate. Mixing of the coal ashmore » « less

Recovery of rare earth elements by liquid-liquid extraction from fresh water to hypersaline solutions

Patent Noack, Clinton W.; Karamalidis, Athanasios K.; Dzombak, David A.

The disclosure describes a method of extraction for optimal recovery of rare earth elements (REE). This includes the optimization of a liquid-liquid extraction technique for economic extraction of REE from chemically complex brines. Through the use of a model, operating conditions are altered to increase separation efficiency. The technique achieves >98% recovery of all rare earth elements in one fraction, while using small volumes of sample and reagents. The method of the present invention recovers REE from previously unexploited waste streams, without need for development of new process equipment and while keeping a small footprint because of the volumes involved.
