Servo Motor Performance At Stepper Motor Prices can now be achieved with advanced yet cost-effective technology from QuickSilver Controls, Inc. For the past 25 years, we have manufactured servo controllers and high torque brushless AC servo motors at stepper motor prices.
QCI markets high-performance, cost-effective, integrated servo motors utilizing high torque hybrid motors, conventional servo motors, and servo controller/drivers for use in the Original Equipment Manufacturer market
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.Download White Paper
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.Download White Paper
“Motor Quality Factor” is the ratio of torque to the square root of power needed to generate that torque. The Motor Quality factor, Kq, gives a good method to compare various motors regardless of winding choices. This white paper compares one of QCI's high pole servo motor to a low pole count conventional servo of simialr size, and explains why QCI's servos are much more efficient, and thus run cooler.Download White Paper
