Rotor and stator assemblies that utilize magnetic bearings for supporting the rotor shall during operation can be suitably used in corrosive environments, such as sour gas. The rotor and stator assemblies include NACE compliant magnetic bearing arrangements for sour gas applications. One embodiment includes the use of barrier layers disposed on selected exposed surfaces of the rotor shaft assembly and/or stator assembly. Also disclosed are processes for forming encapsulated stators that exhibit improved corrosion resistance, as well as corrosion resistant materials for backup bearing races and landing sleeves.

A sensor measures temperature in stationary components of electrical machines using fiber optics. An optical fiber is embedded in a non-metallic ribbon. Notches are cut in the ribbon to effect bends that accommodate a shape of a stationary component. The ribbon and optical fiber are attached to the stationary component. A series of laser pulses can be injected from at least one end of the optical fiber, and the stationary component temperature can be monitored by interrogation of reflections from the series of laser pulses.

Rotor and stator assemblies that utilize magnetic bearings for supporting the rotor shaft during operation can be suitably used in corrosive environments, such as sour gas. The rotor and stator assemblies include NACE compliant magnetic bearing arrangements for sour gas applications. One embodiment includes a stator assembly that comprises a stator sleeve formed of a magnetic material, a sleeve extender coaxial to the stator sleeve formed of a non-magnetic material fixedly attached to each end of the stator sleeve, wherein a point of attachment is heat treated, and a wall formed of the non-magnetic material fixedly attached to the sleeve extender configured to hermetically house a stator and form the encapsulated stator assembly.
