MRT450B-3N-0350-BNNN

The Bosch Rexroth Indramat MRT450B-3N-0350-BNNN from the MRT Synchronous IndraDyn T Motors series by Bosch Rexroth Indramat combines precision engineering with robust performance. This rotor unit features a thermo temperature class of 155 that safeguards internal windings under continuous demand and a maximum input voltage of 600 V for compatibility with high-voltage drive systems. It delivers a rated power of 6.8 kW at a rated current of 22 A and achieves a torque/force constant of 43 Nm/A at 20 °C. Compact yet powerful, it upholds industrial automation standards in direct-drive and rotary table configurations.

With a maximum torque of 1800 Nm, the MRT450B supports heavy-load operations and accelerates seamlessly up to its highest allowed velocity of 2500 min⁻¹ (mechanical). The specified minimum cable cross section of 2.5 mm² ensures safe current flow without voltage drop, while the winding resistance of 1.35 Ohm at 20 °C provides reliable thermal management. Its rated speed identifier "B" designates a standardized frame length that simplifies mechanical integration into existing systems. The robust construction and thermal management protocol guarantee sustained operation under cyclic and continuous duty profiles.

Designed for torque-driven applications in demanding industrial automation and direct-drive motion systems, the MRT450B-3N-0350-BNNN excels in precision positioning and continuous high-torque tasks. Its proven reliability and adherence to thermal temperature class 155 make it ideal for manufacturing environments that require high starting torque and smooth low-speed control. The straightforward mechanical footprint and electrical specifications streamline commissioning and ensure consistent performance throughout long production runs.
