Abstract
A rotary pulser and method is disclosed that includes a housing, a stator supported by the housing, a rotor adjacent to the downhole end of the stator, and a motor assembly coupled to the rotor. A controller may receive a signal that includes drilling information. In response to receiving the signal, the controller causes the motor assembly to rotate the rotor in a first rotational direction through a rotation cycle. The rotation cycle a) rotates the rotor from a first position, where the rotor does not obstruct the at least one passage, into a second position, where the rotor obstructs the at least one passage, and b) rotates the rotor from the second position to a third position in the first rotational direction. Rotation of the rotor generates a pressure pulse in the drilling fluid.
