Abstract
The present disclosure provides an electrical motor configured to operate with conductive fluids internal to the motor without short-circuiting. One embodiment is a telemetry modulator that can include the electric motor and a valve coupled with the electric motor. The valve has a valve stator and a valve rotor, and the electric motor can be used to control accurately the valve opening and closing with valve rotor rotation. The valve rotor can rotate continuously or in oscillations to generate a continuous pressure wave, such as for MWD/LWD communication. The electric motor is configured to allow drilling mud to flow into the electric motor without short-circuiting by the motor stator and/or motor rotor having an electric motor winding and a termination for the winding, the winding and termination having a nonconductive coating. The electric motor can be used in other applications inside and outside the oil field environment.
