MST450B-0012-FT-N0SN-NNNN

MST450B-0012-FT-N0SN-NNNN, Bosch Rexroth Indramat, MST Synchronous Torque Motors presents a high-performance synchronous torque motor engineered for demanding direct-drive applications. This model features a robust liquid cooling system integrated into the stator jacket to maintain thermal stability under continuous high-load cycles. Its advanced three-phase stator winding and permanent magnet rotor deliver exceptional efficiency and precision torque output. Designed for heavy-duty use in rotary tables, swivel axes, and robotics, it sets a new standard for reliability and smooth operation.

Detailed specifications highlight the motor’s core capabilities: a Rated Torque of 540 Nm and a peak Maximum Torque of 1200 Nm ensure ample reserve for dynamic loads. It operates at a Rated Speed of 120 RPM and can accelerate up to 250 RPM for rapid indexing tasks. The unit draws a Rated Current of 22 A and tolerates < Maximum Current of 70 A during peak demands without thermal stress, thanks to a thermal time constant of 4.5 minutes. An inductance of 19 mH and winding resistance of 1.48 Ω deliver predictable electrical characteristics, while the Number of Pole Pairs (30) enables ultra-smooth rotation and fine positioning resolution. Electrical connections are conducted via a cable at the stator end, simplifying cabinet wiring.

Integration into machine platforms is streamlined by its compact frame and standard IP 00 protection, allowing installation in controlled environments with custom enclosures. The motor’s zero-backlash design and precise torque control minimize mechanical wear and simplify feedback loops, even without a built-in encoder. With an ambient operating range of 0 °C to +40 °C, it adapts effortlessly to typical plant conditions. These features make the MST450B-0012-FT-N0SN-NNNN an ideal choice for CNC machining centers, plastics processing, woodworking stations, and any application demanding high torque density, repeatable accuracy, and robust thermal management.
