MST290D-0002-FT-N0SN-NNNN

The MST290D-0002-FT-N0SN-NNNN synchronous torque motor by Bosch Rexroth Indramat in the MST Synchronous Torque Motors series combines high torque density with advanced cooling for demanding industrial motion control. This variant offers a rated torque of 350 Nm at a rated speed of 25 rpm and delivers a maximum torque of 700 Nm at a peak velocity of 90 rpm, ensuring exceptional low-speed performance. With a rated power consumption of 0.9 kW and a compact stator mass of 20 kg, the MST290D-0002-FT-N0SN-NNNN achieves a superior power-to-weight ratio for direct-drive applications. The motor features a winding code 0002 and is equipped with an integrated aluminum cooling jacket for liquid cooling, supporting continuous operation under heavy loads. The frame length D corresponds to enhanced torque capacity, while a power wire cross-section area of 1 mm² facilitates robust electrical connections in confined spaces. This design excels in machinery requiring precise torque control and minimal mechanical backlash.

Performance characteristics reflect meticulous electrical and thermal engineering. The torque constant of 14.9 Nm/A pairs with a voltage constant of 1.64 V/rpm at 20°C to deliver efficient energy conversion and smooth torque output. A winding inductance of 122 mH and winding resistance of 20.6 Ω define the motor’s dynamic response, while a discharge capacity of 15.6 nF ensures rapid voltage stabilization during transient events. The MST290D-0002-FT-N0SN-NNNN incorporates 30 pole pairs to achieve fine resolution of torque pulses and minimize cogging. Thermal management is optimized through a thermal time constant of 3.3 minutes and an integrated stator-cooling jacket, with operation governed by a recommended temperature sensor SNM150.DK. The motor sustains relative humidity between 5% and 95%, and an absolute air humidity range of 1–29 g/m³ for reliable performance in diverse environments.

Engineered for seamless integration, the MST290D-0002-FT-N0SN-NNNN requires no onboard encoder, simplifying system architecture and reducing maintenance. The liquid cooling circuit connects directly to the stator jacket, providing stable thermal protection even under peak loads. An exterior-diameter-optimized cable interface ensures compact installation in robotics, CNC machines, and direct-drive systems. The robust encapsulation and precise winding construction deliver long service life with minimal downtime. Ideal for high-precision indexing, torque compensation, and gearless drive applications, this motor underpins advanced automation solutions across automotive, packaging, and semiconductor manufacturing industries.
