The Bosch Rexroth Indramat MST450E-0012-FH-N0KR-NNNN from the MST Synchronous Torque Motors series combines high torque density and precision control in a compact footprint ideal for direct-drive applications. With a nominal rotational torque of 1400 Nm and a maximum rotational torque of 3250 Nm, it delivers robust performance at a nominal speed of 220 rpm, ensuring stable torque across the entire speed range. The motor’s voltage requirement of 179 volts AC and peak current draw of 125 amperes reflect its electrically demanding design, while an inertia of 1.01 kgm2 guarantees responsive dynamic behavior and rapid acceleration. Advanced liquid cooling (water cooling option) with a power dissipation (cooling) capacity of 3.2 kW maintains thermal stability under continuous duty, even in high-load scenarios.
Equipped with a precision-wound stator featuring a winding resistance of 2.36 ohms and a winding inductance of 4.7 mH, the MST450E-0012-FH-N0KR-NNNN supports rapid current changes and fine torque modulation with minimal loss. The robust housing is engineered to withstand high loads and vibration, making it ideal for heavy-duty industrial environments. Foot mounting provisions ensure secure attachment in demanding installations, eliminating alignment drift even under shock and cyclic loading. Integrated thermal pathways and a dedicated stator cooling jacket interface seamlessly with external liquid circuits to optimize heat transfer and minimize maintenance.
This synchronous torque motor excels in torque-critical applications such as direct-drive rotary tables, tension control systems, and high-performance robotic joints where precision and reliability are paramount. The combination of high continuous torque, low inertia, and efficient liquid cooling makes it a reliable choice for continuous-duty workloads and rapid dynamic cycles. Its compact, heavy-duty construction and straightforward integration simplify system engineering and minimize downtime in automated manufacturing and process control installations.
