MST450E-0012-FT-N0CN-D303

The MST450E-0012-FT-N0CN-D303 from Bosch Rexroth Indramat belongs to the MST Synchronous Torque Motors series and delivers precision motion control across low-speed, high-torque applications. With a defined speed range of 120 to 220 rpm and 30 pole pairs, the motor achieves smooth rotation and minimal cogging for fine positioning. It generates a robust nominal rated torque of 1400 Nm while maintaining a nominal power rating of 17.6 kW, drawing just 46 amperes under nominal load to optimize energy efficiency. The integrated design with a voltage constant of 1.93 V per 1000 rpm ensures linear speed-to-voltage behavior for accurate servo performance.

Under peak conditions, the MST450E-0012-FT-N0CN-D303 delivers up to maximum torque of 3250 Nm with a maximum current draw of 125 amperes, supporting rapid acceleration and deceleration cycles. At 20 °C, the motor’s torque per ampere of 30.4 Nm per ampere enables predictable output across varying load profiles, enhancing control fidelity. Built to Class Protection IP 00 (EN 60034-5) with Class F thermal insulation, it withstands internal temperatures up to 140 °C without compromising performance. Advanced liquid cooling integration via a stator-cooling jacket dissipates heat efficiently for extended duty cycles and minimal thermal drift.

Configured for standard foot-type mounting, this torque motor installs easily into rotary tables, indexing systems, and direct-drive platforms where compact form factors are essential. Its combination of high dynamic torque, stable thermal handling, and precise electrical constants makes the MST450E-0012-FT-N0CN-D303 an optimal solution for machining centers, assembly lines, and other precision automation systems demanding consistent, low-speed performance.
