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 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. 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.
