Abstract

Artificial Lift is utilized to produce oil from a well with no natural flow or to increase the oil production of naturally flow well. One method for artificial lift is the installation of Electric Submersible Pump or ESP. ESP is the most common method and widely used to lift oil from a well. The downhole equipment of the ESP, from bottom, consists of motor, protector, gas separator if needed, and the pump itself. Designing ESP includes selecting the right motor to be installed which is suitable for the pump. Presently, there is more efficient motor technology invented and available in the market. The motor is called Permanent Magnetic Motor or PMM. The conventional motor; Induction Motor or IM; the rotor of the motor consists of electrified copper bar, to induce magnet; while in the PMM motor, the rotor consists of permanent magnet. used is Induction Motor. In this study, the PMM has higher power efficiency, higher and stable power factor, and wider and stable operating speed than IM. The power efficiency of PMM motors is up to 90%, while for IM is only up to 85%.
