Product Description:
The MRS382B-2N-0230-NNNN is supplied by Bosch Rexroth Indramat as part of the MRS Synchronous IndraDyn H Motors series. It is delivered as a frameless stator-rotor kit for direct integration into machine housings where space and inertia must be minimized. Within automated production lines, this kit motor forms the torque source for high-speed spindles, rotary tables, or custom actuators that rely on synchronous magnetic fields for precise positioning and contouring.
The unit can be installed at elevations up to 1000 m without derating, and its winding insulation permits continuous operation in ambient temperatures not exceeding 40 °C. A protection class of IP00 indicates that the host machine enclosure must provide all required protection. Because it has an open kit-motor design, coolant or airflow can be routed directly across the copper and laminations to manage heat generated by electrical losses. The rotor is assembled with permanent magnets, eliminating the need for external excitation and providing high torque density. Two pressure-oil screws secure the laminated stack against axial movement, while a single step-fit seal forms the primary barrier between the stator components and the bearing chamber. Storage is allowed at temperatures up to 60 °C, and transport temperatures may reach 80 °C. Humidity during transit is limited to 75% at 30 °C to prevent condensation on uncoated cores.
Demagnetization safeguards impose additional handling limits. The magnets must cool for 30 minutes after power is removed, and their surface temperature may not exceed 300 °C during coil burnout or resin curing. Before assembly, components should be preconditioned at temperatures no lower than -20 °C to avoid moisture adsorption on insulation films. Long-term warehouse storage permits relative humidity up to 95% when the components are sealed in vapor-barrier bags with desiccant.
