MST130C-0300-NS-N0CN-D303

MST130C-0300-NS-N0CN-D303 from Bosch Rexroth Indramat is a premium member of the MST Synchronous Torque Motors series designed for high-precision applications. This synchronous torque motor features Winding Type 0300 and a frame length C, directly correlating to its enhanced torque capacity. Cooling is managed via Natural Convection, while an integrated stator-cooling jacket allows optional liquid cooling for sustained performance under heavy duty cycles. Its robust iron-core design ensures low cogging torque and exceptional dynamic response across speed ranges.

The motor delivers a continuous Power Rating of 1.1 kW and a rated Torque Rating of 13.5 Nm, optimized for smooth operation at up to Maximum Speed of 1000 rpm. It requires a nominal supply of 279 volts AC and supports a wide Voltage Range of 179V AC to 575V AC, accommodating diverse machine environments. The internal rotor carries 30 pole pairs to minimize torque ripple and secure precise positioning, while Self-lubricating bearings extend maintenance intervals and reduce frictional losses. As a Direct Drive solution, it eliminates the need for gearboxes or belts, reducing mechanical complexity. The compact design weighs only 19 kg and mounts directly to rotary tables or machine spindles.

Engineers value the MST130C-0300-NS-N0CN-D303 for its seamless integration into milling, drilling, and rotary indexing systems, delivering high torque density without backlash. The combination of natural convection cooling and optional liquid circuits ensures reliable thermal management even in continuous operation. Its direct-drive architecture and lightweight construction simplify installation, lower inertia, and enhance dynamic responsiveness, making this motor an ideal choice for precision machining and automation tasks where accuracy and uptime are critical.
