BLM inner-rotor semi-direct-drive oilfield motor

CATALOGUE OVERVIEW

About this motor series

Blue Light’s BLM inner-rotor oilfield motor is intended for retrofitting beam pumping units. Its semi-direct-drive arrangement removes the belt stage, using a compact, thin motor structure and modular installation. For a retrofit inquiry, the existing pumping-unit interface and drive arrangement are more useful than a generic motor frame alone.
