Product Description:
The MRS242D-2N-0100-NNNN rotor is manufactured by Bosch Rexroth Indramat for the MRS motor line. As the rotating core of a spindle motor, it provides the inertial mass and magnetic surface needed for torque generation. This makes it a critical component in precision machine tools and automated production spindles that depend on stable high-speed rotation.
The rotor’s mechanical profile begins with an internal bore of 100 mm, allowing it to seat on a matching shaft with accurate concentric alignment. Overall shaft engagement is defined by a total length of 345 mm, which gives designers enough room for bearing placement and sensor elements. Its geometry is identified as size 242, while frame-length code D defines the axial build used within the motor family. Windings and slot insulation meet thermal class F, supporting operation at elevated temperatures during prolonged spindle duty.
Operation is permitted within a surrounding air range of 0–40 °C, which suits controlled industrial environments with managed ambient temperatures. The rotor carries a protection rating of IP00 because it is enclosed by the stator assembly during use. The hub is machined for a step interference fit, and that fit creates the secure shrink connection needed to transmit spindle torque without keys. As part of the IndraDyn H family, the design follows established balance and vibration limits for smooth running.
