Product Description:
The MRT530F-3N-0410-NNNN rotor is produced by Bosch Rexroth Indramat for the MRT Synchronous IndraDyn T Motors series. As the rotating element of a direct-drive torque motor, it transmits high continuous torque directly to the load without mechanical reduction. This direct connection supports precise positioning in presses, winders, and machine tools while avoiding the backlash associated with gear-driven systems. The component is the rotor of an MBT torque motor and is supplied as a standalone subassembly for use with the corresponding stator. Its open design also accommodates the liquid-cooling circuit required within the machine assembly.
The rotor has an internal diameter of 410 mm and a frame size of 530, allowing it to fit the stator cavity with the same designation. Its mass distribution produces a moment of inertia of 2.3 kg·m², which the drive controller uses when calculating acceleration and deceleration ramps. Accurate inertia data helps the control system reduce overshoot during rapid indexing movements. For thermal management, the motor accepts coolant through a hollow shaft, and the rotor tolerates inlet pressures up to 6 bar. The rotor itself does not require electrical insulation, but the complete installation has an IP00 protection class and therefore requires appropriate guarding against contact and contamination. Screws secure the rotor along the flange to maintain concentric alignment with the machine shaft and transfer operating loads through the joint.
The permitted storage temperature ranges from -25 to +55 °C, while the allowable shipping temperature ranges from -25 to +70 °C. These limits allow the assembly to remain in warehouses without climate control before it is installed. During operation, the rotor and stator must remain within an ambient temperature range of 0 to +40 °C. The cooling circuit accepts inlet temperatures from +5 to +40 °C, helping maintain stable magnetic and adhesive properties throughout extended operating cycles. Keeping the coolant within the permitted range also supports consistent heat transfer from the stator without exposing the motor materials to excessive thermal stress.
