Product Description:
The MST360D-0018-FT-N0SN-NNNN is a synchronous torque motor produced by Bosch Rexroth Indramat within the MST Synchronous Torque Motors series. As a direct-drive component, it eliminates mechanical transmissions and delivers high torque at low shaft speeds for indexing tables, extruders, and similar motion axes in industrial automation. Water cooling removes heat from the stator, while thermal encapsulation stabilizes the windings against cyclic temperature swings during continuous duty. This arrangement also reduces backlash that can appear with gear-driven systems and supports smooth low-speed operation under heavy loads.
At the nominal operating point, the motor outputs 12.90 kW by producing 525 Nm at 235 rpm and drawing a rated current of 28.3 A. The torque constant is 18.50 Nm/A, so drive current rises in direct proportion to developed torque. The voltage constant is 1.300 V/rpm, which means back electromotive force increases with speed. The stator inductance is 14.4 mH, and it influences current ripple and the response of the drive current loop. The dc winding resistance is 1.6 ohms, which affects copper losses during continuous load. At standstill, the motor can hold 640 Nm while drawing 34.6 A when the shaft is locked, and thermal encapsulation helps keep temperature rise within allowable limits during that condition.
The motor can generate up to 1150 Nm during acceleration or short process surges, provided the inverter can supply a peak phase current of 72.0 A. Its thermal time constant is 5.0 min, so short overload periods are possible before the winding temperature rises significantly. The electrical speed range reaches 350 rpm, giving a useful margin above the nominal operating speed for process changes. This higher limit supports applications that need both steady low-speed torque and brief increases in shaft speed during cycle transitions.
