MST161E-0050-FT-N0CN-NNNN

The Bosch Rexroth Indramat MST161E-0050-FT-N0CN-NNNN from the MST Synchronous Torque Motors series combines robust construction with precision performance, featuring a speed rating of 500 rpm and a rated rotational torque of 105 Nm in its standard configuration. This motor achieves a maximum speed of 1000 rpm while delivering a maximum rotational torque of 270 Nm, making it uniquely qualified for applications demanding both high torque and elevated rotational speeds. The stator is equipped with a dedicated liquid-cooling jacket to ensure optimal thermal regulation, and its frame length designation E signifies enhanced torque capacity over shorter variants. Designed for direct-drive installations, the MST161E-0050-FT-N0CN-NNNN eliminates the need for gearboxes or shaft-lock mechanisms, improving efficiency and reducing maintenance points.

The liquid cooling system is calibrated for efficient heat dissipation, with a Power Loss (Liquid Cooling) of 3 kW under continuous operation. Inlet coolant temperatures between 10 to 40 °C enable stable winding temperature control, while a Permissible Inlet Pressure of 3 bars ensures reliable flow even under variable supply conditions. The cooling circuit maintains a Coolant Flow Rating of 4.3 liters/min and endures a Pressure Drop Rating of 0.1 bar across the integrated jacket. With a Coolant Duct Volume of 0.26 liters, the motor’s low fluid content expedites temperature stabilization and minimizes coolant inventory.

Integration flexibility is ensured through direct-mount flanges compatible with standard process interfaces, and the absence of an onboard encoder allows pairing with user-selected position feedback devices and advanced controllers. As a true direct-drive solution, this MST motor delivers smooth torque transfer directly to the load, supporting high-precision indexing, rotary actuation, and dynamic motion processes without backlash. Its combination of medium-speed capability, high continuous torque, and advanced liquid cooling makes it ideal for demanding industrial automation, robotics, and rotary press applications where reliability and performance are paramount.
