Product Description

The MRS312D-2N-0130-NNNN is rotor by Rexroth Bosch Indramat, featuring a 312D body frame. With a step interference fit construction, the MRS312D-2N-0130-NNNN interlocks with the shaft safely, maximizing torque transfer. The MSR rotor has an internal diameter of 130 millimeters. The MRS312D-2N-0130-NNNN employs a set of fixing screws and threaded pins for rotor balancing. Particularly, the MRS312D-2N-0130-NNNN has 12 mounting screws and 24 M8 bolts for balancing. Based on its datasheet, this rotor has an outer radius of 215 mm and a depth of 419 mm.

Weighing about 67.4 kilograms, the MRS312D-2N-0130-NNNN is labelled as a massive rotor unit, capable of delivering high torque output at limited speeds. Because of its large surface area, this rotor can withstand high radial forces during continuous operation. Based on documentation, the MRS312D-2N-0130-NNNN withstands the following radial and axial forces: 11,480 N and 690 N. For AC rotors, radial forces are those forces whose points of application are directed tangentially on the shaft surface. Subjecting the rotor beyond its permissible radial loading may cause shear deformation on the rotor shaft.

With an excitation voltage of 750 VDC, the MRS312D-2N-0130-NNNN can achieve its maximum synchronous speed of 1200 or 2400 rpm, depending on the IndraDyn stator used. When paired with the MSS312D-0060 stator, this indraDyn H unit can deliver a consistent torque output of 820 Nm at a speed range of 600 to 2,400 rpm.
