Product Description:

The MRT130C-3N-0060-NNNN is a rotor component produced by Bosch Rexroth Indramat for the MRT Synchronous IndraDyn T Motors series. Installed in direct-drive torque motors, it forms the rotating element that mounts to machine tables or hollow shafts and turns stator-generated magnetic force into controlled rotary motion. This layout is used in indexing tables, printing drums, and positioning axes that require accurate angular movement without backlash from gears or belts. Because the rotor works as part of a direct-drive assembly, the axis can respond smoothly to commanded position changes while keeping drivetrain compliance low.

The rotor is secured by eight tapped bores with M5 × 10 mm threads. Its mounting method is screw mounting, and the 8 threaded holes spread clamping force evenly around the ring to help maintain balance during rotation. The unit has an IP00 protection class, so protection from dust, liquids, and accidental contact must be provided by the surrounding machine housing. Rotor temperature must not exceed +100 °C, which helps protect the magnetic material during operation. This open design is suited to assemblies where the motor parts are enclosed inside the machine structure rather than exposed to the surrounding environment.

The rotor has a polar inertia of 0.00180 kg·m², which keeps acceleration demand moderate during rapid indexing and speed changes. An internal bore of 60 mm provides clearance for large shafts and can also support through-routing in machine layouts that use a hollow center. The assembled mass is 1.5 kg, which helps limit bearing load while still giving the rotating assembly stable mechanical behavior. These values make the part suitable for motion systems that need quick response, compact packaging, and accurate torque transfer across repeated positioning cycles.
