Product Description:
The MST530E-0010-FT-N0RN-NNNN is a frameless torque motor designed by Bosch Rexroth Indramat for the MST Synchronous Torque Motors series. This direct-drive unit provides high continuous torque at low rotational speed, allowing builders of extruders, print rollers, or rotary tables to couple the stator straight to the load without intermediary gear stages. By removing mechanical transmission elements, the motor improves positional accuracy and reduces maintenance demands, while its thermal encapsulation supports long duty cycles in industrial automation cells. That arrangement is useful in applications where backlash and drivetrain compliance would reduce process accuracy.
Under nominal operating conditions, the motor supplies 2100 Nm of rated shaft torque at 90 rpm, corresponding to a mechanical output of 19.8 kW. Achieving this operating point requires a rated phase current of 64.0 A, while the copper windings present 0.59 Ω of resistance to manage I2R losses. For intermittent load peaks, the electromagnetic section can produce a maximum of 4700 Nm without demagnetization. These torque levels help drive heavy cylinders or reels directly while maintaining low-speed accuracy without external reduction gearing. The low synchronous speed also helps preserve high positioning resolution in closed-loop servo systems.
Thermal management relies on liquid cooling that circulates through integral jackets. The cooling circuit must provide 9.5 L/min at up to 6.0 bar inlet pressure to hold stator temperature within limits, and it connects through a radial side port with a large outside diameter that keeps hoses clear of the mounting face. When accelerations demand higher magnetizing force, the inverter may command up to 212.0 A, and the 32.80 Nm/A torque constant provides a predictable relationship between current and torque. Dynamic current steps are filtered by the motor’s 7.5 mH inductance, while the 16.0 mm² power conductors support continuous service. This cooling layout helps the motor remain compact while handling sustained torque in demanding rotary applications.
