Product Description:
The MST360D-0012-FT-N0CS-NNNN torque motor is manufactured by Bosch Rexroth Indramat as part of the MST Synchronous Torque Motors series. Supplied as a frameless stator for direct-drive assemblies, it is intended to deliver high continuous torque at very low rotational speeds. This arrangement allows gear-free motion in rotary tables, plastics extruders, and similar automation axes that require precise positioning and smooth force delivery.
This stator uses a liquid-cooled jacket, so heat is removed directly from the copper windings and the laminated core. The three-phase winding system has an inductance of 43 mH and a resistance of 5.7 Ω at 20 °C, parameters that influence current rise time and I²R losses. A torque constant of 31.82 Nm/A links drive current to mechanical output, while installation must respect a maximum phase current of 60 A to avoid magnetic saturation. Additional electrical data include a rated current of 16.5 A, a discharge capacity of 13.5 nF that affects insulation behavior during transient overvoltage, and a voltage constant of 2.580 V per rpm related to back-EMF characteristics. The stator mass is 28.8 kg, providing thermal inertia and structural stiffness, and power loss during full duty is 3.60 kW, which must be handled by the cooling circuit.
At the operating point, the motor supplies 525 Nm of torque at a rated speed of 120 rpm, yielding a continuous mechanical output of 6.60 kW. Applications may briefly demand the peak envelope where torque reaches 1150 Nm before protective limits intervene. The design also supports overspeed to 250 rpm for intermittent motion profiles, although efficiency is optimized at the 120 rpm setpoint. With winding inductance and resistance matched to modern inverters, the stator produces smooth, ripple-free torque while the liquid cooling stabilizes temperature during sustained operation.
