MST530D-0012-FH-NNKR-NNNN

The Bosch Rexroth Indramat MST530D-0012-FH-NNKR-NNNN from the MST Synchronous Torque Motors series delivers robust performance with a rated power of 22 kW and an operating voltage of 575 V AC (3-phase). This precision torque motor features an input frequency of 50–60 Hz and is built on a frame size D housing to support high-torque applications. A total of 35 poles combined with a nominal torque of 2100 Nm and a substantial motor weight of >100 kg ensure stable low-speed operation. The winding resistance of 0.52 ohms @ 20°C and inductance of 7.5 mH contribute to smooth current flow, while EMC capacitor compatibility guarantees electromagnetic compliance.

Reliability is enhanced through a dedicated liquid cooling system integrated into a stator-cooling jacket, maintaining thermal stability under continuous load. The motor's low internal resistance reduces heat generation, enabling longer duty cycles without derating. With a precision-balanced rotor and noise rating of 75 dB, it provides quiet operation even under full torque. Additionally, the design emphasizes a low rotor inertia of 1.92 kgm2, facilitating rapid acceleration and deceleration for dynamic positioning tasks.

Installation requires a controlled, enclosed environment since the MST series does not carry an ingress protection rating. The motor is ideally suited for direct-drive applications in robotics, rotary tables, and tension control systems where high static torque and precision are critical. Supported by Bosch Rexroth Indramat controllers or compatible third-party drives, this synchronous torque motor streamlines commissioning and optimizes machine performance.
