Servo Controllers and Servo Motors for Cost Effective Motion Control

Servo Motor Performance At Stepper Motor Prices can now be achieved with advanced yet cost-effective technology from QuickSilver Controls, Inc. For the past 17 years we have manufactured servo controllers and high torque brushless AC servo motors at stepper motor prices.

Be an Energy Hero in your Business

  • Save Energy (Save Money)
  • Reduce Waste. Close Loop means less Scrap (Save Money)
  • Reduce HVAC Load (Save Money)
  • Save the Earth (Preserve somewhere to spend money)

QuickSilver Controls products are efficient and run cooler than standard step drive motors and require 50% to 75% less energy to run. Less heat produced means lower HVAC. Smoother motion means longer fixture life.

QuickSilver products are durable. Lower Replacement costs! Good for everyone: Customers and Planet!

What Makes QuickSilver Controls Different?

Our servo controllers convert traditional microstep motors into hybrid servo motors also known as closed loop stepper motors. What the industry commonly refers to as a “stepper motor” is, more accurately, a 2 phase, 100 pole, AC brushless motor. Our digital controllers use a four quadrant vector drive (similar to a variable frequency drive) to drive our 2 phase AC motors just like traditional servo motors are driven. Since we use servo motor control rather than microstep control, our motors are more efficient (run cooler) and do not stall like traditional micro stepper motors.

Why Servo a Microstep Motor?

The servo market has made several transitions over the years. One of the more recent is a wider use of microstep capable step motors as primary movers in servo systems. This transition has been fueled by the growing availability of powerful Digital Signal Processors at affordable prices, as well as control algorithm development. These new step motor based servos include true servo motors using control algorithms which modulate motor torque to perform the requested motion, as well as pseudo servo motors which dynamically vary the step rate to prevent loss of steps.
