Although servo motors have an unquestionable performance capability, the final performance is mostly determined by the servo loop tuning. This application note provides some practical guidelines how to make servo loop tuning a deliberate engineering exercise.
Rotary stages incorporate a precision worm-gear drive mechanism and bearing components for accurate positioning performance.
ACR-55UT rotary stage has very wide dynamic speed range and can move at sub-rpm speed with very low velocity ripple and accelerate quickly to 1,000 rpm.
These rotary tables provide angular positioning and velocity control with zero backlash, and no gear wear or gear vibration.
This 130 mm center aperture stage features a micro-step drive enabling angular speed up to 20 deg/s.
RTHM-153 stages are designed to rotate optical components and small tooling in confined spaces.
Cartesian Multi-Axes Systems are suitable for automation applications including pick and place, assembly, test and inspection, dispensing stations.
SRT Rotary Table with direct drive servo motor technology eliminates backlash, reduces the number of mechanical components and provides stiff mechanical system for highly dynamic applications.
Model RTH-4 rotary tables provide angular positioning and eliminate backlash, friction and wear problems associated with worm, gear and belt drives.
BSMA-058 is a motorized ball-screw carriage guided by a linear bearing.
LSMA-175 low profile precision linear actuator is a single axis system for applications that require low profile narrow positioning stages.
Direct drive RR-18-14 provides angular positioning and eliminates backlash, friction and wear problems associated with worm, gear and belt drives.
RTHM-100 stages feature an angular resolution 0.1 arc-sec, which may be achieved with either DC Servo or stepper motor controls.
The Cartesian system is capable of velocities 2m/sec and offers a cost effective, compact envelope planar linear positioning system.
