Product Description:
The MRT130E-3N-0060-NNNN is a frameless rotor component built by Bosch Rexroth Indramat for the MRT Synchronous IndraDyn T Motors series. It serves as the rotating element of a direct-drive torque motor and installs inside the machine structure. The rotor delivers high torque without gear reduction, reducing the number of mechanical transmission components required between the motor and the load. This design supports indexing tables, rotary machining axes, and similar motion systems used in industrial automation.
With an axial stack length of 120 mm, the rotor provides a magnetic path that balances a compact installation with continuous torque capability. Its central shaft opening has a 60 mm H7 bore with a +0.03 mm tolerance, allowing the rotor to slide over a precision spindle or hollow shaft without additional sleeves. The outer diameter is limited to 84.9 mm, providing clearance for the stator laminations and surrounding bearings in compact housings. Inner mounting locations use a 4 × M4 thread pattern, 8 mm deep and spaced at 90°, which can accommodate lightweight preload devices. Peripheral fixtures can use an 8 × M5 thread pattern, 10 mm deep and spaced at 45° to secure encoder targets or balancing weights.
The open construction has an IP00 protection rating, so the completed machine must provide suitable protection against contact, debris, and moisture. Rotor inertia is 0.00290 kg·m², providing moderate resistance to acceleration and supporting smooth servo control when the motor is paired with high-resolution feedback. The rotor has a mass of 2.2 kg, which limits the added load on the supporting bearings during operation. Its frameless design requires accurate alignment between the rotor, stator, shaft, and feedback device during assembly. Proper installation clearances also help prevent contact between rotating and stationary components while preserving the intended direct-drive operation.
