Claim 12:
13. A method for controlling an electrical submersible pump assembly, comprising:
positioning a rotational transmitter assembly on a shaft of a motor wherein the rotational transmitter assembly comprises:
a cylindrical body having an axial length, a first end configured to fixedly attach to the shaft, a second end having an end face, a circumferential face positioned on an outer surface of an outer diameter of the cylindrical body and a pocket positioned within the circumferential face;
a permanent magnet having a magnetic field comprising a first polarity and a second polarity wherein the first polarity is opposite from the second polarity, the permanent magnet positioned in the pocket substantially flush with the circumferential face;
a hollow cylindrical cover configured to be positioned over the outer surface and over the permanent magnet and configured to secure the permanent magnet in the pocket;
a lip positioned on the second end having a lip diameter larger than the outer diameter of the cylindrical body configured to secure the hollow cylindrical cover on the cylindrical body;

positioning a stationary sensor on a housing of the motor proximate the circumferential face;
starting the motor;
attempting to sense a magnetic field using the stationary sensor; and
determining a rotational parameter of the motor.
