Product Description:
The MST360D-0012-FT-N0RN-NNNN from Bosch Rexroth Indramat is a direct-drive synchronous torque motor in the MST Synchronous Torque Motors series. As a stator-rotor assembly for low-speed, high-torque applications, it is used in rotary tables, extruders, and printing drums where gearing can be eliminated. By coupling the load directly to the motor shaft, the MST360D-0012-FT-N0RN-NNNN provides precise angular positioning and steady rotational force in automated production lines and other equipment that benefits from direct-drive motion.
Continuous operation is supported by a liquid-cooling jacket that measures 150 mm along the stator body, allowing dissipation of losses created by a nominal phase current of 16.5 A. Under these thermal conditions, the motor delivers 6.6 kW of mechanical output while maintaining a shaft speed of 120 rpm and a continuous torque of 525 Nm. Power and feedback conductors exit radially through the stator end, which helps cable routing in tight housings, and the windings use thermo-encapsulation to keep coolant separated from the electrical slots. Because the unit is supplied without an encoder, external feedback devices or sensorless control must be used for operation.
During rapid indexing, the rotor can handle dynamic loading with an inertia of 0.27 kg·m², and it can accept a momentary phase current of 60 A to reach a top speed of 250 rpm and a peak torque of 1150 Nm. These limits allow brief overloads during startup and disturbance rejection without exceeding normal thermal limits. An outside diameter of 385 mm provides a large pole surface that helps sustain magnetic flux at low operating speed. The large diameter also supports the torque-producing surface needed for direct-drive applications. The sealed winding package helps protect insulation when duty cycles alternate between constant load and short peak demand.
