ZeroTouch non-contact metrology platform

A non-contact 3D traction motor inspection system that measures complex geometries and performs defect detection.

Non-contact 3D Motor Inspection System

The ZeroTouch® traction motor inspection system is a non-contact motor inspection system that generates a 3D point cloud, providing manufacturers with real-time metrology and inspection data to optimize production processes, detect defects, and improve ROI.

Increases Accuracy

Increases Throughput

Detects Defects

ZeroTouch measured the entire part surface, generating a high-density, micron-level point cloud.

ZeroTouch executed the entire stator frame inspection plan in just 20 seconds versus the tactile methods, which took several minutes.

ZeroTouch executed the entire stator assembly inspection plan in a few minutes versus the tactile methods, which took several hours.

ZeroTouch measured all surfaces on all leads in 3D and identified weld defects too.

Data Integrity and The Digital Twin, Part 1

Metrology is moving from the lab to the manufacturing line, which brings non-contact techniques, digital twins, and the integrity of point clouds versus discrete measurement data under increased scrutiny.

Data Integrity and The Digital Twin, Part 2

In the second installment of Data Integrity and the Digital Twin, we delve deeper into the value of big data, tactile and non-contact measurement errors, and the magic of mathematics.

Overcoming Challenges in High-speed Inspection Using Non-contact Metrology, Part 1

When product quality and throughput are vital, performing high-speed, quality inspections present unique challenges that require precision solutions.
