Motor Components Top Sub & Rotor Catch

At the top end of the motor is the top sub, which is a
crossover housing between the power section and the
rest of the BHA. Most top subs accommodate API float
valves. The top sub also provides a seat for the rotor catch
system.

The rotor catch is a retaining device which minimizes the

possibility of losing motor components downhole in the
unlikely event that an external connection breaks or
backs-off. The rotor catch is attached to the top of the
rotor by a threaded connection.

Power Section
The power section is a positive displacement motor
comprised of a rotor and a stator. The rotor is a long, spiral
shaft with a number of external, curved lobes. The stator
has a similar spiral profile formed internally by the stator
elastomer, but is designed to have one more lobe than the
rotor.

The design results in a cavity for fluid to flow into. As

pressure increases, the cavity progresses down the rotor
by forcing the rotor to rotate and progress around the
spiral profile. This action converters hydraulic horsepower
into mechanical horsepower delivered to the drill bit.

The desired lobe configuration will vary depended on the

application. In general, a power section with fewer lobes
generates a lower torque and higher speed, and a power
section with more lobes generates a higher torque and
lower speed.

Since the power section is a positive displacement motor,

speed and torque are determined independently from
each other during operation.

The rotational speed is proportional to the fluid flow rate

through the power section. The higher the flow rate, the
higher the output speed.

The torque generated is proportional to the differential

pressure across the power section. Differential pressure
is created by applying a load to the bit, thus the more
weight applied to the bit, the higher the differential
pressure across the power section.

For each power section configuration, there is a limit to

how much differential pressure the power section can
handle. If the differential pressure increases beyond the
elastomer limitations, the power section will no longer
keep the fluid cavities travelling down the rotor separate
from each other causing the rotor, and thus the bit, to stop
rotating. This is commonly known as a stalled motor and

The thrust bearings are designed to sustain the applied

(80% of 1130 psi) at temperatures up to 200F and 768 psi
at 250F (68% of 1130 psi).
