MST531L-0009-FT-N0SN-D303

The Bosch Rexroth Indramat MST531L-0009-FT-N0SN-D303 from the MST Synchronous Torque Motors series delivers exceptional performance with a standstill torque of 6750 Nm and a maximum torque of 12000 Nm right from zero speed. This synchronous torque motor achieves a rated torque of 5000 Nm at a rated speed of 90 RPM and sustains a rated power of 47.10 kW under continuous operation. The design incorporates 25 pole pairs to ensure ultra-smooth torque delivery and low ripple. With a maximum electrical speed of 110 RPM and a standstill current of 132.3 A, this motor is engineered for high-precision, high-torque applications.

Engineered for demanding environments, the MST531L-0009-FT-N0SN-D303 features a thermal time constant of 6 minutes that facilitates rapid thermal response and protects the winding insulation under fluctuating loads. The motor’s low winding resistance translates into reduced losses and higher overall system efficiency, while its robust construction ensures stable operation during dynamic duty cycles. Integration into liquid-cooled systems is seamless thanks to the factory-equipped cooling jacket, matching perfectly with modern drive architectures. High torque density combined with precise current-to-torque conversion allows this motor to excel in indexing, oscillating and continuous-rotation duties.

Cooling efficiency is maintained with a Cooling Mode of Water Cooling, enabling optimal heat removal at high power levels and ensuring continuous performance even under elevated ambient temperatures. The liquid cooling capability supports a range of industrial fluids, delivering consistent thermal management for extended duty cycles. Compact and durable, the MST531L-0009-FT-N0SN-D303 is ideal for machine tools, robotics, and process equipment where high torque at low speeds and reliable thermal control are critical to productivity.
