Optimized Permanent Magnet Motor Control for Electric Submersible Pumps Using LV ASDs

Advancements in motor technology are leading to the increased use of permanent magnet motors (PM motors) in a variety of applications. One of these applications is electric submersible pumps because this technology brings several benefits over conventional induction motors. When permanent magnet motors are combined with adjustable speed drives, there are further benefits, particularly when the drive utilizes sensorless flux oriented control of these synchronous machines rather than the typical volts per hertz control. This paper will go into detail on this new technology and the benefits which are realized with its use.
