Accuracy, Repeatability, and Specsmanship – Understanding Motion Stage Datasheets
[EDITOR’S NOTE: This blog post discusses accuracy and repeatability in the context of data sheets and product specification. For a detailed discussion of stage accuracy, repeatability, and resolution that covers definitions, nuances, and misconceptions, read our whitepaper here.] In theory, a datasheet lists the capabilities and performance of a device,...

Novanta Acquires Motion Solutions
Novanta Inc. (Nasdaq: NOVT) (“Novanta” or the "Company"), a trusted technology partner to medical and advanced technology equipment manufacturers, announced today that it has finalized a definitive agreement to acquire Motion Solutions, a leading provider of highly engineered integrated solutions.
The Six Myths of Stage Error Mapping
Stage-error mapping – measuring absolute positioning error at a specified set of sampling points – has gained a reputation as a method for achieving high-accuracy motion control with lower-cost equipment. The theory is sound. The problem is that there are a lot of misconceptions around stage-error mapping that can lead to its use in unsuitable applications, with disappointing results. Want to dispel the myths of stage-error mapping and learn how you can use it for maximum benefit? Read on.
How do we measure stage accuracy? The Motion Solutions laser laboratory has metrology testing equipment used to characterize our high-precision stages. Our 6-axes laser interferometer allows us to simultaneously measure linear accuracy, repeatability, pitch, yaw, roll, flatness, and straightness.
Why do we need an overhead crane? At Motion Solutions, we build large high-precision equipment that weighs thousands of pounds and needs to be handled with care.
Modeling and FEA Expertise Deliver Better Designs Faster
Finite element analysis (FEA) lets engineers explore the behavior of complex systems under real use conditions, running simulation after simulation to optimize overall performance by way of small design tweaks. The challenge is that FEA results are only as accurate as the simulation setup, as the saying goes, “garbage in...
