QuickSilver Controls, Inc. has announced a full range of NEMA 23 frame Direct Drive Hybrid Servo Motors is available. Four stack sizes provide 80 oz-in (.56 Nm) through 430 oz-In (3 Nm) continuous torque, with top speeds from 1,000 to 4,000 RPM.
Hybrid Servo motors are well suited for Direct Drive applications, eliminating the need for gear heads in most applications. These high torque motors match well to loads in the 500 to 2,000 RPM speed range, typical of lead screws and belt drives, and can provide a significant increase in both power and efficiency over conventional servo motors in these speed ranges.
The PVIA control system includes patented damping methods to allow wide ranges of inertial mismatch without retuning or notch filters, reducing the need for inertial matching of the motor to the load. 100:1 inertial mismatch ratios are easily tuned.
The intuitive command language allows for easy program creation/modification/debug using the free QuickControl environment available from their web site. The programming environment provides for two programming threads in addition to an active motion. Sophisticated programs can be easily implemented. Serial communications include MODBUS RTU, 8bit ASCII, 9bit binary, and DMX512. CANopen is simultaneously available with the serial options.
Seven IO are provided for external interfacing. Programmable terminations allow the IO to be pulled high, pulled low, or floated while in input mode. All of the IO may also be used as analog inputs, with one channel also supporting 0-10v analog control.
