Product Details:

REXROTH 180C-B35RR1-BS01-D2N1 is a heavy-duty DC servo motor designed for Bosch Rexroth legacy high-torque nutrunner tightening spindle. It features reinforced rotor structure and stable torque output for heavy bolt fastening applications. This legacy motor is discontinued, and most available stock are refurbished spare parts for old automotive powertrain and chassis fastening stations.

This servo motor works with resolver or encoder angle feedback and torque transducer to realize dual closed-loop torque and angle fastening control. It delivers sufficient power for large bolts and supports precise tightening stages. Separate power and signal wiring reduces electromagnetic interference from inverters and workshop equipment. It is a standalone motor unit without gearbox, torque transducer or built-in holding brake.

The internal winding adopts Class F insulation and integrates PTC temperature sensor for overheat protection. The heavy metal motor housing reaches IP54 protection grade against workshop dust and incidental coolant splash. Optimized magnetic design suppresses torque ripple and ensures consistent torque output for safety-critical heavy bolt connections. Standard flange interface supports modular assembly with gear unit and torque sensor for convenient on-site replacement.

All tightening logic and quality parameters can be configured via Rexroth tightening software. Every finished motor passes factory inspection including feedback signal matching test, insulation resistance test, cyclic load endurance test and vibration stability test to guarantee reliable operation in multi-shift heavy-duty automated fastening production lines.

It is widely deployed on automotive chassis assembly stations, heavy mechanical fastening lines and high-capacity torque calibration benches. Typical application scenarios include heavy spindle power drive units, spare replacement parts for aging nutrunner systems and drive components for refurbished high-torque spindle assemblies. Automation integrators select this Rexroth motor for its strong torque capacity and seamless compatibility with Rexroth nutrunner tightening ecosystem.
