Permanent Magnet Motor Solutions

We have the only proven controller solution with closed-loop-Flux Oriented Control (F.O.C.) for permanent magnet motor artificial lift systems (Downhole Driven Permanent Magnet Motor PCP's and PMM-ESP's)

Flux O.C. Advantages (vs Vector Control):
+ Ideal sinusoidal motor current eliminates current interruption and therefore lots of harmonics. This ensures optimal motor efficiency ALWAYS.
+ Utilize motor reluctance torque properly (increases the motor torque capability).
+ No limit for cable length.
+ Enhance motor starting process.
+ Increase accuracy of speed estimation
+ Better control of transformer inrush current and saturation
+ Better dynamic performance due to vector control

CILA2S PMM Versatility


The CiLA2S is currently controlling 3 different brands of PMM's in the field with unmatched control with more already proven in the lab. This includes both surface and internal mounted PM motors. The CILA2S is able to control different brand motors for ESP-PMM's, ESPCP-PMM's, and Surface PCP-PMM's.

CILA2S PMM Field Results

With the patented Flux Oriented Control, the power factor is always 1 regardless of the load. For wells with oversized motors, noticeable gas or light oil production, or operating at lower speeds as shown below, the efficiency still remains extremely close to 1.

PMM Motor, Pump, Drive, and Sensor Testing


At our Houston manufacturing and testing headquarters we are able to test any ESP or surface/downhole PCP motor (IM/PMM), pump, drive, or sensor for compatibility, software development, and efficiency evaluation. We are able to simulate various loads and electrical sags to validate performance. Please contact us if you would like a tour of the facility or to test a solution and see the advantage of the CILA2S PMM Flux Oriented Control.
