Product Overview
The Industrial-Grade Resolver for High-Torque Apps is a rugged position-sensing device engineered to withstand the extreme demands of heavy-duty machinery. Derived from military-grade technology with over 50 years of field validation, this resolver delivers absolute position feedback in environments characterized by high vibration, extreme temperatures, and contamination . Unlike standard resolvers, it is optimized for high-torque applications (up to 10,000 Nm), featuring reinforced bearings, robust housings, and enhanced signal processing to maintain accuracy under mechanical stress. With an IP67 rating and operating temperature range of -30°C to 125°C, it excels in industries such as steel manufacturing, wind energy, and marine propulsion .
Product Features
High-Torque Bearing System
Equipped with oversized double-row bearings, the resolver supports radial loads up to 100 lbs and axial loads up to 50 lbs—critical for high-torque motors where shaft deflection and mechanical stress are significant . This design extends bearing life to 10,000+ operating hours.
Extreme Environmental Resistance
The 316 stainless steel housing provides corrosion resistance against saltwater, chemicals, and industrial solvents, while the IP67 rating ensures protection against dust ingress and temporary submersion (up to 1m) . This makes it suitable for offshore and coastal applications.
Vibration and Shock Immunity
Tested to withstand 20G continuous vibration and 50G shock loads, the resolver maintains signal integrity in heavy machinery like stamping presses, rolling mills, and mining equipment . Its brushless design eliminates wear points vulnerable to mechanical stress.
EMI/RFI Shielding
Integrated shielding protects against electromagnetic and radio-frequency interference common in industrial environments with variable frequency drives (VFDs) and high-voltage equipment, ensuring stable position feedback even in electrically noisy settings.
Wide Speed Compatibility
Operates reliably at rotational speeds from 0 RPM (static position) up to 6,000 RPM, making it suitable for both low-speed high-torque applications (e.g., extrusion machines) and high-speed industrial motors.
Applications
Wind Turbine Generators
Used in pitch and yaw systems of wind turbines, providing precise position data to control blade angle and nacelle orientation—maximizing energy capture in variable wind conditions.
Heavy Machinery
Integrated into steel rolling mills, hydraulic presses, and forging equipment, where high torque and vibration resistance ensure accurate control of material shaping processes.
Marine Propulsion
Employed in ship and offshore platform propulsion systems, withstanding saltwater exposure and high torque loads to optimize engine performance and fuel efficiency.
Mining Equipment
Used in conveyor belt drives, crushers, and drilling machinery, where dust resistance and durability prevent unplanned downtime in remote mining operations.
FAQ
What makes this resolver suitable for high-torque applications?
Its reinforced bearing system and stainless steel construction handle the shaft loads and mechanical stress generated by high-torque motors, while maintaining position accuracy .
How does the resolver handle temperature extremes?
With an operating range of -30°C to 125°C, it performs reliably in cold climates (e.g., offshore wind farms) and hot industrial environments (e.g., steel mills) without calibration drift .
Can the resolver be retrofitted into existing machinery?
Yes, it offers drop-in compatibility with common industrial motor mounting standards (NEMA, IEC), with hub shaft and solid shaft options to match legacy equipment.
What is the expected service life in continuous operation?
Under normal operating conditions, the resolver provides 100,000+ hours of service—equivalent to 11+ years of continuous use—due to its brushless design and robust bearing system.
