Abstract
A downhole assembly and method are provided for selective activation of a motor in a drilling string. The downhole assembly includes a stator and a rotor assembly. The rotor assembly comprises a rotor body having a fluid passage extending between an inlet and an outlet, the fluid passage extending through at least part of the length of the rotor; and a ball catch component comprising a receiving end and an interior seat for receiving and retaining a blocking implement, and a fluid passage. When no blocking implement is retained in the rotor assembly, the fluid passage permits flow of drilling fluid entering the receiving end to the fluid passage of the rotor body. The fluid thereby bypasses the motor, which is not activated. When a blocking implement is in place, drilling fluid flows around the ball catch component and into the motor to thereby activate the motor.
