Abstract
A stator for a downhole-type motor includes a housing. The housing includes a sleeve. The sleeve includes a first layer, a second layer, and a third layer. The first layer is erosion-resistant. The second layer is corrosion-resistant. The third layer can provide structural support. The stator includes a motor stack. The stator can be used to drive a rotor disposed within an inner bore of the housing.
