MST210C-0027-FT-N0SN-NNNN

The Bosch Rexroth Indramat MST210C-0027-FT-N0SN-NNNN belongs to the prestigious MST Synchronous Torque Motors series, engineered for applications requiring high torque at low speeds. This variant delivers a rated power of 3.4 kW, a rated torque of 120 Nm, and a rated speed of 270 rpm. Designed as a synchronous torque motor, it provides precise, continuous torque output for demanding tasks such as robotics, machine tools, and special machinery.

This motor features a robust frame size of 210 and incorporates 20 pole pairs for smooth, low-speed operation. The discharge capacity is 9.5 nF, ensuring stable electrical performance, while the winding resistance of 4.9 ohm at 20 °C and a winding inductance of 28.6 mH provide predictable electrical characteristics. The torque constant of 9.2 Nm/A (at a winding overtemperature of 100 K) underscores its efficiency in converting phase current into mechanical force. An aluminum cooling jacket supports liquid cooling, maintaining optimal temperature under continuous S1 loading.

Durability and integration are enhanced by thermal encapsulation within the stator-cooling jacket, which thermally decouples the motor housing from the machine, and by the cable-connected electrical interface with a reduced outer diameter for streamlined installation. The motor’s black primal coating (RAL 9005) adds corrosion resistance and longevity. With a manufacturing tolerance of 5 % on its torque constant and a stator mass of 11.5 kg, this motor offers reliable performance in industrial environments. Its design, free of onboard encoders, allows flexible integration with external feedback systems, making it ideal for high-precision, heavy-duty applications.
