Submersible permanent magnet motors for PCPs and ESPs

Novomet offers submersible permanent magnet motors in series: 319 (OD 3.19”) and 456 (OD 4.56”).
Motors are three-phase and oil filled.
Poles on rotor are created by permanent magnets from hard magnetic sintered materials.

Benefits of permanent magnet motors vs. asynchronous motors

• For the same power output PMMs are smaller in size and weight and have higher:
  • efficiency,
  • power factor,
  • electromagnetic torque
• Lower heat release
• Possibility for variable speed control
• Energy consumption is reduced by 30%
• Automatic maintenance of brake horsepower at different pump operating modes

Application area of PMMs is enhanced as they can be used in wells with highly viscous oil, with increased amount of solids.
