Product Description:
The MRS102D-1N-0046-NNNN rotor is produced by Bosch Rexroth Indramat for the MRS Synchronous IndraDyn H Motors series. It serves as the rotating core of a spindle-class synchronous motor. In CNC machining and other automated equipment, it transfers magnetic drive power to tooling or work-holding devices.
A frame size of 102 mm establishes the stator envelope, and frame-length code D sets the axial stack height for matching housings. An internal bore of 46 mm accepts the spindle shaft or drawbar sleeve, and the total rotor length of 186 mm supports a precise fit within the motor assembly. Because it carries a protection rating of IP00, it requires a fully enclosed motor structure for environmental shielding.
Thermal limits are set by an ambient range of 0 to 40 °C, and staying within that range helps prevent heat buildup that could affect the rotor stack. Insulation in the surrounding stator conforms to class F, so continuous operation must remain compatible with that temperature class. The design variant is Standard, with no added slots, sleeve coatings, or hollow cooling channels. As part of the IndraDyn H spindle family, it supports high surface velocities and quick acceleration changes.
Wake Industrial offers a 1-year warranty on every rotor and can arrange same-day shipping when scheduling is tight. The chat tool available on the website can be used for general questions about type codes or fault indicators. Its dimensional fit, enclosure requirement, and thermal compatibility make it suitable for spindle assemblies that depend on stable running at demanding production speeds during daily operation.
