The Bosch Rexroth Indramat MRT450E-3N-0350-BNNN from the MRT Synchronous IndraDyn T Motors series by Bosch Rexroth Indramat is engineered as a high-performance rotor unit within the MRT (IndraDyn T rotor unit) product group. This Motor Size 450 assembly incorporates an Inside Diameter Of Rotor 350 mm and is built to an Motor Length E specification for seamless integration into direct-drive torque motor systems. The rotor’s Rotor Mass 4.8 kg and Rotor Moment of Inertia 0.64 kg·m² deliver refined torque at low speeds, while robust materials meet rigorous industry demands. Designed for industrial automation, this component supports legacy and next-generation stator interfaces.
The MRT450E-3N-0350-BNNN supports a Maximum Input Voltage 600 V and operates up to a Highest Allowed Velocity (mechanical) 2500 min⁻¹, with an optimal continuous Maximum Mechanical Speed 1400 rpm under load. Thermal management is assured by its Thermal Temperature Class 155, enabling reliable duty cycles in demanding environments. The Mounting Style/mechanical Design fixing per screws (Code: 3N) ensures precise alignment and repeatable installation torque. Its Conformity Mark CE certification confirms compliance with European Economic Area standards, guaranteeing safety and environmental regulation adherence.
Manufactured in Slovenia, the unit bears a unique Serial Number Unique Identifier e.g., 7800101123456 and carries the production code marking of Production Location Made in Slovenia to verify traceability. The Other Design NNNN code reserves optional expansions while maintaining a current build without accessories. Together, these features deliver a dependable, precision rotor solution optimized for industrial automation, motion control, and high-torque direct-drive applications.
