PERMANENT MAGNET MOTOR
The Borets Permanent Magnet Motor (PMM) is designed for the same ESP systems as induction motors. However, the PMM shows better performance in harsh environments, such as viscous fluids, high solids content, unstable inflow, low production, post hydro-fracturing or any other artificial lift methods applied.
Moreover, it facilitates the operating procedure for well start up.Under certain operating conditions, a sucker-rod pumping system can be replaced with an ESPCP featuring
a permanent magnet motor.
The PMM design is similar to the induction motor design, though the PMM uses a rotor with permanent mag-nets that are made of sintered hard-magnetic materials.
PMM Operating Principle
The magnets supply the rotor flux that requires less electric power. The operation of a rotor and stator is synchronized due to the rotor and stator flux maintained at 90° angle, and thus the rotor slip tends toward zero.
The PMM designed for operation with electrical submersible pump is equipped with a high-speed rotor. The rotation speed ranges are from 500 to 3900 rpm.

Permanent Magnet Motor vs. Induction Motor
Below are the load, efficiency and cos φ curves intended to compare a PMM and induction motor with 36 kW
nominal horsepower.
The curves show that compared to the IM, the PMM has lower input and idle current, higher efficiency rate
and power factor.
Due to lower power consumption at the same output power and absence of power loss in the rotor, more
favourable thermal operating conditions are ensured compared to the induction motor.

Borets has carried out a series of research studiesA set of measurements have been made to define power consumption of ESP systems operated by several
oil companies and installed in wells with equal operating conditions. The wells were equipped with induction and
permanent magnet motors of the same horsepower and variable frequency drives.
According to our estimates and calculations, the ESP system operating with a PMM is 10-20% more energy
efficient than the ESP system with IM.
