A-C motors for oil-well pumping

摘要

Studies have been made to determine the most desirable motors to be used for oil-well pumping. From consideration of the type of load, starting requirements, cost, and operating conditions it was found that high-torque motors with 5- to 8-per cent slip will give best service on polyphase lines and 2-value capacitor-type motors will be best on single-phase lines.
