Product Description

The MRS142D-2N-0050-NNNN is a stellar rotor package manufactured and developed by Bosch Indramat Rexroth under the Synchronous IndraDyn H product series. It features one of the smallest body frames available under the IndraDyn H series. It has an internal diameter of 50 millimeters and an outer diameter of 83 millimeters. To fasten the MRS142D-2N-0050-NNNN inside the spindle housing and the stator package, a set of 12 M6 threaded pins is used. These threaded pins also help in balancing the rotor and maintaining stable operation since they are separated equally at 30-degree intervals. Based on its dimension sheet, the MRS142D-2N-0050-NNNN has a depth of 211 millimeters.

With an MSS142D-0700 stator, the MRS142D-2N-0050-NNNN can achieve a rated speed of 7,000 rpm. At this driving speed, the unit can transmit an effective torque output of 40.5 Nm. Considering these rated parameters, the MRS142D-2N-0050-NNNN can be considered a high-performing rotor package, capable of driving heavy loads at impressively high shaft speeds. At most, this rotor can transmit a peak torque of 90 Nm. When the DC bus voltage for this rotor package is increased from 540 V to 750 V, the peak speed of 19,000 rpm may be achieved.

With its step interference fit, the MRS142D-2N-0050-NNNN features a moment of inertia of 0.014 kg(m^2). With its compact dimensions and low moment of inertia, this rotor package excels more for high-speed applications. Like all other MRS rotors by Rexroth Bosch Indramat, the MRS142D-2N-0050-NNNN operates at a limited ambient temperature range of 0 to 40 degrees Celsius and exhibits a protection mode of IP 00. Since this rotor package comes without a chassis, it is vulnerable to liquids and dust particles.
