Fit
This is a key performance factor that indicates how loose or tight the power section’s rotor fits inside the stator.

Stator Tube
This steel tube protects the interior components from extreme drilling environments during operation and connects the power section to the rest of the motor components.

Elastomer
This specially formulated rubber lines the inside of the stator tube. Its profile defines how the power section operates downhole.

Rotor
This helical-shaped steel component spins inside the stator, its profile rotating against the stator’s interior elastomer lining.
