Product Details:

REXROTH 0360-500-00/MF01 is a compact high-dynamic DC servo motor from Bosch Rexroth EC304 series, specially developed for the modular automated nutrunner tightening spindle system. It features low rotor inertia and fast acceleration and deceleration performance, perfectly matched with Rexroth tightening controllers to realize high-cycle repeated bolt fastening. The suffix MF01 represents the special feedback and shaft configuration for spindle assembly. This legacy motor is a discontinued spare part, widely used for replacement and maintenance of old automotive fastening stations.

This servo motor transmits incremental pulse and commutation signals to the matched Rexroth tightening controller, cooperating with torque transducer to complete dual closed-loop torque and angle monitoring. It supports multiple fastening strategies, and homing operation is required after power-up to establish rotation reference. Separate power and feedback connectors reduce electromagnetic interference in industrial cabinets equipped with inverters and switching modules.

This variant is non-brake motor design without integrated holding brake. It is installed inside the modular tightening spindle, suitable for automotive powertrain assembly lines, new energy component fastening stations and household appliance bolt joining fixtures. The standard flange interface supports direct replacement without modifying the spindle mechanical structure. The armature winding uses Class F insulation material and integrates thermal sensor for real-time temperature monitoring to prevent overheating damage during continuous cyclic fastening operation. The motor housing reaches IP54 protection grade to resist workshop dust and minor coolant splash. Optimized magnetic circuit suppresses torque ripple greatly, maintaining stable rotation and consistent fastening precision.

It supports torque control, speed control and position control modes, and all tightening parameters can be configured via Rexroth tightening software. Its compact body saves cabinet and spindle installation space. Every finished motor passes factory validation including encoder signal calibration, high-cycle start-stop endurance test, insulation resistance inspection and vibration test to guarantee stable performance in multi-shift automated fastening production lines.

It is widely deployed on automotive engine assembly stations, battery module fastening lines, material torque test benches, small mixed-model assembly fastening cells and rotary multi-spindle tightening fixtures. Typical application scenarios include servo spindle driving modules, closed-loop torque-angle fastening units, high-cycle bolt driving assemblies and renovation spare units for old nutrunner systems. Automation integrators select this EC304 servo motor for its fast dynamic characteristic, compact weight and seamless matching with Rexroth nutrunner tightening ecosystem.
