Abstract

Methods and apparatus are provided for a controlling an electric motor that is at least partially disposed within a motor housing. The rotational speed and position of the electric motor are sensed, and a temperature of the electric motor is sensed. The sensor signals are converted to optical signals and are propagated in a fiber optic cable. The electric motor is controlled based, at least in part, on the propagated optical signals.
