Robotic arms, humanoid exoskeleton, and industrial machinery all rely on compact, high-performance actuators. To meet these needs, a leading player in integrated motion systems turned to Hutchinson for a solution that could deliver unmatched angular precision.
Tailor-Made Innovation: Dual-Track Nonius Magnet Rings
Standard magnetic targets offer an accuracy of ±0.1°, which fell short of the client’s expectations. Hutchinson responded with a bespoke design: a pair of dual-track Nonius magnetic rings integrated into a compact, high-performance encoder.
This development has involved:
• A custom product design tailored to the client’s embedded electronics.
• An optimized manufacturing process to ensure enhanced mechanical and magnetic precision.
The first ring controls angular position, while the second measures speed—critical for motor control. Together, they form a reliable, compact magnetic encoder.
Proven Performance in Extreme Conditions
Hutchinson’s solution stands out for its:
• Ultra-high precision: absolute angular measurement of ±0.02°, validated under extreme conditions.
• Compact integration: seamlessly fits into existing electronic architectures.
• Reliable repeatability: consistent performance even in constrained environments.
• Easy implementation: rings adapt to existing setups, simplifying final assembly.
• Technical partnership: close collaboration throughout the development process.
A Ready-to-Use Sensor-Actuator System
This breakthrough enables our customers to integrate a fully operational sensor-actuator system straight out of the box, without calibration or adjustment. It simplifies implementation, reduces development costs and eliminates the need for additional components.
