Scorpion Series Drives


Highly Powerful & Lightweight Servo Drive Line

Scorpion-20151216-600This extremely powerful, lightweight controller is the smallest high power drive of this complexity on the market today. The Scorpion incorporates our rugged controller and power driver modules, offers a wealth of feedback options, and is packaged in a potted plastic case. This versatile servo module line is ideal for high power military, aviation, automotive, robotic, and specialized industrial applications where size and weight are critical.

Dynamic Power & Pocket-sized

The Scorpion operates at 865 V and is the latest innovative solution in our highly capable servo drive lines. This modular solution is small enough to fit in your pocket yet powerful enough to power up a high voltage ground vehicle. It is an exceptionally powerful controller in our expanding high voltage product line.

To achieve this level of performance, the Scorpion is strategically packaged in a potted plastic case, allowing for extreme durability in a compact size. Similar to our preexisting servo drive lines, it is ruggedized and compact. Unlike a typical control unit of this scale, the Scorpion, like its larger cousins, is engineered to withstand conditions that would destroy other motor controllers.

Feature highlights include:

  • 2.6” D x 4.0” W x 1.8” H in size – Meets your most stringent dimensional requirements
  • Single axis configuration – Dedicated power
  • Lightweight and Highly Efficient – Ideal for mission critical systems that require dependable performance
  • Torque, Velocity, or Position Control – Expanded control options let you cater the Scorpion to your specific requirements
  • Multiple feedback options – Powerful yet user friendly
