Linear Encoders for Production – Integrated Measuring Machines
Up to now, measuring machines have operated in a largely familiar, exactly defined environment, since their performance is significantly determined by the signal quality and accuracy of their linear encoders. Now, with the trend toward production-integrated measuring machines, the measurement device in use should be clearly reviewed.
Torque in Servo Motors
When specifying servo motors for a new machine or CNC retrofit, there are many specifications regarding servo motor performance. One of the most confusing is the differing torque specifications of the motor. Torque can be specified in Newton meters (Nm) or more commonly foot pounds (lb-ft) or inch pounds (lbf-in).
Inductive Rotary Encoders for Resolver Systems with a Higher Resolution
The inductive rotary encoders of the HEIDENHAIN ExI 1100 series are now available in versions whose mating dimensions are the same as those of common types of resolvers. Depending on the respective applications and accuracy requirements, inductive or optical absolute encoders are now possible as high resolution alternatives to resolvers.
