Product Details:

REXROTH 093C-0-DC-4-C/110-A2/WI573LV/S005 is a dedicated DC servo motor for Bosch Rexroth modular automated nutrunner tightening spindle, WI573LV is the core motor type for this part number. It runs on 110V power supply, with low inertia rotor design and fast dynamic response for high-cycle repetitive bolt fastening processes. This motor belongs to the discontinued legacy tightening assembly system, most available units are refurbished spare parts for old automotive fastening stations.

This servo motor works together with Rexroth resolver/encoder angle feedback and torque transducer to complete dual closed-loop torque and angle fastening control. It supports fast forward rotation and controlled slow fastening stages, and homing operation is required after power cycle to establish rotation reference. Separate power and feedback wiring layout reduces electromagnetic noise interference inside industrial cabinets equipped with inverters and welding equipment.

This variant is standalone servo motor without integrated output gearbox or torque transducer. It adopts standard flange interface for modular assembly with gear unit, torque sensor and S005 output structure. The internal winding is Class F insulation and fitted with built-in temperature sensor for overheat protection during continuous cyclic fastening. The sealed motor housing reaches IP54 protection grade to resist workshop dust and incidental coolant splash. Optimized magnetic design suppresses torque ripple, ensuring stable speed and torque output for safety-critical bolt joints.

All tightening programs, torque tolerance and process logic are configured via Rexroth tightening software. Its compact body size allows installation inside narrow rotary indexers and limited automation space. Every finished motor passes factory validation including resolver signal matching test, high-cycle start-stop endurance test, insulation resistance check and vibration stability test to guarantee reliable performance in multi-shift automated fastening production lines.

It is widely deployed on automotive powertrain assembly stations, new energy battery module fastening lines, household appliance bolt joining fixtures and torque calibration test benches. Typical application scenarios include spindle driving modules, closed-loop torque-angle fastening power units, mixed-model assembly servo drive spare parts and renovation components for old nutrunner systems. Automation integrators select this WI573LV motor for its fast dynamic performance, stable 110V operation and seamless matching with Rexroth modular nutrunner tightening ecosystem.
