Product Description:

The MST530C-0010-FT-N0CN-NNNN torque motor is supplied by Bosch Rexroth Indramat within the MST Synchronous Torque Motors series. The unit is an outer-stator, inner-rotor assembly intended for flange integration into machine frames where precise low-speed motion and high turning force are necessary. By coupling directly to the driven load, it removes backlash, improves positioning accuracy, and shortens maintenance intervals in automated presses, indexers, and winding systems.

Under continuous rating, the motor supplies 1200 Nm while consuming a rated current of 31.2 A and generating 12.60 kW of mechanical power. Peak demands are covered by a standstill torque of 1440 Nm and a standstill current of 37.4 A, with the electrical design permitting a maximum shaft torque of 2700 Nm and a 88.0 A crest current during short transients. The electrical speed ceiling is 140 min⁻¹, so full torque is available well below typical spindle speeds. A winding inductance of 24.6 mH slows current rise, and the 2.810 V min⁻¹ voltage constant indicates the back EMF the drive must overcome. Power leads sized at 6.0 mm² match these current levels and simplify cabinet wiring.

The stator insulation exhibits 15.2 nF of leakage capacitance, a value that affects common-mode current the drive filter must handle in high-frequency switching environments. Mechanical output per phase current is set by a torque constant of 38.50 Nm/A, enabling predictable controller tuning across the operating range. Liquid cooling is supported through an internal channel holding 0.90 L of coolant; continuous flow through this duct stabilizes winding temperature and protects magnet integrity. Electrical losses at steady load are determined by a phase resistance of 2.0 Ohm, so heat generation scales with squared current and must be considered when selecting chiller capacity.
