MST210A-0027-FT-N0CN-D303

The MST210A-0027-FT-N0CN-D303, Bosch Rexroth Indramat, MST Synchronous Torque Motors model is a high-precision synchronous torque motor engineered for dynamic performance in demanding applications. It delivers a rated speed of 270 rpm and a high torque of 50 Nm while drawing a rated current of 7 A at 1.4 kW rated power consumption. The motor features a stator-cooling jacket and uses liquid cooling to maintain optimal thermal conditions during continuous operation. A robust frame length “A” construction supports the integrated cooling circuit and contributes to the motor’s compact footprint and enhanced torque density.

The MST210A-0027-FT-N0CN-D303 showcases advanced technical specifications that ensure consistent performance under peak loads. It achieves a maximum torque of 100 Nm and a peak velocity of 600 rpm with a maximum root-mean-square current of 25 A. Electrical characteristics include a winding inductance of 53.3 mH, a discharge capacity of 4.8 nF across the U, V, W power terminals, and a torque constant of 7.1 Nm/A at 20 °C. The motor’s thermal time constant of 2.4 min reflects its rapid heat dissipation via the liquid cooling circuit, which holds 0.18 l coolant volume and requires a flow rate of 6 l/min to manage 1.2 kW of power dissipation loss. A power wire cross-section area of 1 mm² supports reliable current delivery, while the 20 pole pairs design ensures smooth torque output and low cogging.

Engineered for seamless integration, the MST series motor mounts directly to standard drive controllers and incorporates a stator end cable-strand design for simplified electrical connections. The use of liquid cooling and thermal encapsulation enhances operational reliability, extending motor lifespan in continuous-duty cycles. Ideal for robotics, rotary indexing tables, and precision positioning systems, the MST210A-0027-FT-N0CN-D303 delivers accurate torque control, reduced maintenance, and consistent performance in the most exacting industrial environments.
