MST530G-0007-FT-N0CN-D303

The MST530G-0007-FT-N0CN-D303 from Bosch Rexroth Indramat, part of the MST Synchronous Torque Motors, delivers a robust 31 kW of continuous power at a rated velocity of 70 rpm. This liquid-cooled synchronous torque motor features a frame length G design that supports up to 9200 Nm of peak torque. Its large-pole architecture comprises 35 pole pairs (70 poles total), optimizing torque density and smooth operation. Supplied without an encoder, this model relies on a direct electrical connection via a large-diameter stator cable to simplify integration and reduce auxiliary hardware needs.

The motor employs liquid cooling through an integrated stator-cooling jacket to maintain thermal stability under heavy-duty operation. Winding performance is characterized by a winding resistance of 0.9 ohms and an inductivity of 10.8 mH, while embedded discharge capacitance of 50.7 nF dampens electrical transients. A substantial stator mass of 144 kg provides structural rigidity and steady torque output, and power control circuits utilize 1.5 mm2 cross-section wiring for reliable current delivery. Thermal safety is enforced with warning and shutdown thresholds set at 145 C and 155 C respectively, complemented by built-in PTC temperature sensors for real-time monitoring.

Designed for seamless integration into high-precision systems, the MST530G excels in torque-critical environments such as CNC machines, robotics, and rotary indexers. Its high pole count and liquid cooling ensure consistent torque delivery with minimal ripple, while the rugged stator construction and temperature safeguards guarantee long-term reliability. When paired with Bosch Rexroth modular drive units, this motor accelerates commissioning and supports maintenance-free operation in demanding industrial applications.
