When converting from off-the-shelf motion technology to a customized embedded solution, a major life sciences company chose Simplexity to minimize development risk.

By tightly integrating the 2-Axis stage into the product architecture, Simplexity helped the client deliver a more compact instrument.

The Specifics

•Translated high-level product requirements into a detailed motion sub-system specification.

•Architected a 2-axis motion sub-system capable of 10 micron repeatability including the specification of all motors, sensors, encoders, bearings, belts, and lead screw elements.

•Developed the firmware and electronics for brushless DC motor control including techniques for executing fast and accurate small moves without introducing unwanted vibration.

•Developed a manufacturing process of die-casting and post-machining to achieve highly accurate positions.

•Developed a test bench to measure accuracy and repeatability.

•The test bench was used to characterize motion performance during development, to qualify component substitutions, and to ensure out-bound assembly quality at the contract manufacturer.
