Product Description:
The MRT530G-3N-0410-NNNN rotor belongs to the MRT Synchronous IndraDyn T Motors series from Bosch Rexroth Indramat. The component serves as the rotating core of a direct-drive torque motor used in industrial automation to deliver high continuous torque without intermediate gearboxes. When paired with the corresponding stator, this standard version rotor provides positionable motion for rotary tables, extruder screws, or printing cylinders, letting the machine builder achieve precise speed control through electronic commutation rather than mechanical transmission. This arrangement also helps reduce backlash and supports smooth low-speed rotation in precision indexing applications.
The inside rotor diameter of 410 mm offers a large through-bore for power, air, or material feed-through while maintaining magnetic coupling surface. A rotor mass of 77.0 kg works with its moment of inertia of 3.84 kg·m² to smooth load disturbances and to set predictable acceleration profiles in the drive controller. The magnetic circuit produces up to 9710 N of radial attraction between rotor and stator, while axial pull is limited to 565 N, so only moderate bearing preload is required. Continuous service speed must stay at or below 1100 rpm to respect mechanical stresses and thermal limits.
Mechanical attachment follows the fastening-by-screws concept. The rotor face contains 40 equally spaced M10 holes, each machined to a depth of 20 mm, giving repeatable clamping force and alignment accuracy. Its IP00 protection class indicates that no built-in shielding exists against dust or liquids, so the rotor must be housed inside a sealed machine frame with dedicated cooling airflow. The screw pattern helps distribute clamping load evenly across the rotor face during operation and helps keep the mounting surface stable under magnetic pull.
