Variable speed drives

Control submersible and surface pumping systems

Variable speed drives (VSDs) provide reliable power, protection, and control of electric submersible pump (ESP) and horizontal surface pumping system (HPS) installations. SpeedStar VSDs enable you to

reduce overall operating costs, potential energy fines, and levies
decrease workovers and replacements
prolong pump run life
increase total efficiency
increase production.

The SpeedStar VSD minimizes stress on the system via low- and medium-voltage options for the specific power requirements of your application. With thousands sold globally, SpeedStar VSDs are widely used and suitable for most mature production situations, including brownfields.

The SpeedStar 519 SWD VSD combines integral output sine wave technology and meets IEEE 519 guidelines.

Low-voltage SpeedStar VSDs

SpeedStar 2000 Plus and SpeedStar SWD VSDs

The SpeedStar 2000 Plus VSD is used typically with HPSs. The SpeedStar SWD VSD, which has an integral output sine wave filter, is used typically with ESPs; the output voltage wave form is similar to that of a true sine wave and thus results in less voltage stress and a longer life for the motor, cable, and other electrical components.

Both the SpeedStar 2000 Plus and SpeedStar SWD VSDs provide harmonic control in 6- and 12-pulse configurations. For 6-pulse low-voltage drives (LVDs), the electric current is typically distorted 25%, depending on the power system impedance. The 12-pulse LVDs halve the distortion to 11%.

SpeedStar 519 SWD 18-pulse, low-voltage sine wave VSD

This sine wave VSD reduces the distortion to 5% and provides clean power to the downstream device. On the basis of standard harmonic guidelines, these VSDs achieve 18-pulse harmonic cancellations by using a patented phase-shifting integral autotransformer. This design is significantly more efficient than a typical low-voltage drive system that uses an external isolation phase-shifting transformer, further reducing operational costs.

Our VSDs are among the most reliable in the industry, with a mean time between failures (MTBF) design philosophy of 5 to 10 years for low- and medium-voltage drives respectively.

SpeedStar MVD medium-voltage VSD

Suitable for either indoor (NEMA 1) or outdoor (NEMA 3) use, both versions of the SpeedStar MVD VSD come standard with a visible fused disconnect switch, precharge circuitry, and sine wave output filter tailored for controlling and protecting high-horsepower ESPs. With current distortion typically under 5%, the SpeedStar MVD VSD practically eliminates harmonics concerns and enhances electric power efficiency.

Indoor—The indoor VSD has an integral 24-pulse input isolation transformer.

Outdoor—As the first in the industry, the outdoor VSD has an integral 36-pulse input isolation transformer, and unlike all indoor MVDs, it does not require installation in a climate-controlled environment.

The NEMA 3R version of the SpeedStar MVD VSD is intended for outdoor installations and can supply from 500 to 1,500 hp.
