Product Description:

The MST130C-0300-NS-N0CN-D303 is a frameless synchronous torque motor developed by Bosch Rexroth Indramat within the MST Synchronous Torque Motors series. Designed for direct integration into rotary tables, indexing heads, and printing cylinders, this motor eliminates gearboxes by applying torque directly at the application flange. In industrial automation, it supplies precise angular positioning and steady low-speed rotation while minimizing mechanical backlash for accurate motion sequences in assembly machines, packaging lines, and machine-tool axes. Because the motor is frameless, it is installed directly into the surrounding machine structure instead of a separate motor housing.

Its continuous operating range includes a rated torque of 6.8 Nm delivered at a rated speed of 3000 rpm. Under these conditions, the electromagnetic package outputs 2.136 kW of mechanical power while drawing a phase current of 5.3 A. Heat generated in the stator is removed through self-cooling, so no external liquid or forced-air circuit is required. This arrangement reduces the need for auxiliary cooling components around the axis. An ingress protection rating of IP00 means the motor must be mounted inside a protected housing, where airflow and insulation can be managed as needed. Standard encapsulation shields the windings against vibration and maintains dielectric strength, and the stator jacket length is 113 mm.

For intermittent peaks, the electromagnetic system can supply a torque of 40 Nm while accepting up to 26.6 A from the drive, providing headroom for acceleration or brief positional corrections. The stator body’s outside diameter is 150 mm, so it fits compactly around a matching rotor and bearing set in tight machine frames. The slim form supports installation in space-limited assemblies where direct-drive performance is needed without adding transmission components. It is also well suited for reversing and indexing tasks that benefit from low rotating mass and fast response.
