Product Description:

The MST130C-0200-NS-N0CN-D303 is a permanent-magnet torque motor produced by Bosch Rexroth Indramat within the MST Synchronous Torque Motors series. Designed for direct-drive duties, the unit generates high continuous torque without intermediate gearing, allowing tight position control in rotary tables, printing cylinders, and extruders. Integration is simplified because the stator can be secured directly inside machine frames, so the rotor couples to the load through a large hollow shaft. This construction eliminates backlash and reduces maintenance demands in precision automation lines.

Under continuous operation, the motor runs at a rated speed of 2000 rpm, generating mechanical output up to 5.24 kW. At that point, the phase windings draw a thermal steady-state current of 15.2 A, while short-term load peaks are handled by a permissible current of 38 A before protection circuits intervene. Heat produced by copper losses is removed by natural convection, and fins on the stator outer surface transfer energy to the ambient air so no auxiliary blower or liquid circuit is required. The absence of forced cooling simplifies cabling while still supporting the rated power level under the series operating conditions.

No external coolant path is fitted because there is no cooling jacket, which keeps the outside diameter compact for tight machine housings. Power and feedback leads exit through an axial connector on the larger OD side, facilitating short cable runs inside enclosures. Position feedback hardware is omitted, so there is no motor encoder, and the drive must rely on external sensors or open-loop commutation. Windings use standard encapsulation to guard against vibration and moisture ingress, and the stator is mounted in the machine housing with shoulder bolts that align it concentrically to the bearing stack.
