Servo Motors and Servo Controllers
for Advanced Motion Control

Servo Motor Performance At Stepper Motor Prices can now be achieved with advanced yet cost-effective technology from QuickSilver Controls, Inc. We manufacture servo controllers and high torque brushless AC servo motors at stepper motor prices.

 

More Torque for Less Money

Our systems are typically $300-400 less than traditional servo motors, yet have 2-4 times their continuous torque. In addition, only a single cable is required for the NEMA 17 and 23 frame servos motors (see above for example systems). We also support many 3rd party micro stepper motors.

 

What Makes Us Different

Our servo controllers convert traditional microstep motors into servo motors or 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. We have all the accuracy, precision, and power savings of traditional servo motors with the higher torque and lower cost of traditional stepper motors.

 

Power Saving/High Efficiency

Efficiency is key. Our servo controllers run cool–which means low power or high efficiency. Our patented drive technology, combined with the inherent power savings of closed loop (servo) vs. open loop (stepper) yields power savings. Since our motors run closed loop (servo) the driver only puts as much current into the motor as required to put the motor on target, verses a stepping drive which runs at full current most of the time. The result–our motors run cooler and require 50%-75% less energy than the same motor used on a step drive. On a 24/7 application, this represents over $100/yr savings.

 

High Inertial Loads

Our digital four quadrant driver and servo loop uses advanced motion control algorithms to take advantage of our high-torque capability, providing direct-drive of high inertia loads such as flywheels and belt drives. These load inertias may be as large as 100 times the motor inertia (100:1 inertia mismatch) while still providing smooth responsive positioning control. Traditional servo systems typically cannot exceed a 10:1 inertial mismatch.

 

Rapid Application Development

QuickControl®, our Windows® based development software, is very easy to use and is designed to get the first time user programming moves in minutes. Using a simple menu driven approach, you quickly select commands from a list and enter the required parameters. You may create and download a program to the controller by following the simple tutorial or cut and paste code from many examples. QuickControl includes many features to debug your programs such as single step, trace, breakpoint, and register watch.
