Abstract
A system and method to for communicating with a telemetry tool by generating mud pressure waveforms is disclosed according to one or more embodiments. The system includes a rotor having a first bore spaced axially apart from a second bore and a blade disposed therebetween, a stator having a first and second component with a portion of each stator component disposed in a respective one of the first and second rotor bores, and an actuator having a tubular core wrapped with a winding and a plurality of magnets. The rotor blade includes a plurality of cutouts that may be aligned with a plurality of through bores disposed on each stator component when the rotor is in an open position. The core, winding, magnets, and rotor operate like a limited angle torque motor to electromagnetically produce torque by reciprocatingly rotating the rotor within an angle of rotation.
