MSK071D-0450-FN-M2-UG2-RNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK071D-0450-FN-M2-UG2-RNNN from the MSK IndraDyn S Synchronous Motors series is a high-precision IndraDyn S Synchronous Servomotor engineered for demanding automation tasks. This motor size 071 unit features a compact motor length D housing combined with a rated speed code 0450 design to deliver balanced dynamics and torque density. Built with design: increased concentricity, the rotor assembly minimizes radial runout and optimizes bearing life under cyclic loads. As a product type: IndraDyn S Synchronous Servomotor, it supports seamless integration into Rexroth drive systems.
Liquid cooling through the Cooling: Liquid cooling circuit ensures consistent thermal management, while the Encoder Technology: Optical system provides reliable feedback. The encoder’s Encoder Turn Type: Multiturn Absolute capability, paired with an Encoder Interface: EnDat2.1, delivers precise positional data over the full motion range. A Encoder Connector: Rotatable, 240° arrangement simplifies installation in tight cabinets and reduces cable stress. With an Encoder Resolution: 2048 signal periods, the motor supports high-resolution control for advanced motion profiles. The shaft type: Plain shaft design and integrated holding brake, electrically-released option with holding brake torque: 30 Nm enable secure load holding and safe deceleration. The motor also requires cooling FN to maintain peak performance under sustained operation.
Electrical characteristics include a continuous current at standstill 100 K: 17.6 A rating and a continuous torque at standstill 100 K: 20.0 Nm, providing robust holding capacity. Dynamic performance peaks at a maximum current: 69.3 A and a maximum torque: 66.0 Nm, ensuring rapid acceleration for demanding cycle rates. The stator’s winding inductivity: 3,200 mH contributes to smooth current profiles and predictable torque production across the speed range.
