Abstract
A fluid pressure pulse generating apparatus including a pulser assembly and a fluid pressure pulse generator and methods of using the fluid pressure pulse generating apparatus. The pulser assembly comprises a motor, a sensor for detecting rotation of the motor, a driveshaft rotationally coupled to the motor, and processing and motor control equipment communicative with the motor and the sensor. The fluid pressure pulse generator is coupled with the driveshaft. The sensor provides an indication of the amount of rotation of the motor and this information can be processed by the processing and motor control equipment to determine the position of the driveshaft and to control rotation of the driveshaft based on a predetermined rotational relationship between the driveshaft and the motor.
