Product Description:

The MSK071D-0450-NN-S2-UP2-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It supplies closed-loop rotary motion for positioning, forming, and handling axes that require stable torque delivery and accurate velocity control throughout repetitive machine cycles. Its D-length stator and size 071 frame provide a compact industrial motor package, and the shaft with a keyway connects directly to couplings or pulley hubs so torque can be transmitted without intermediate gear stages.

This motor relies on natural convection, so installation must provide unobstructed air passages that satisfy the Cooling FN requirement. An electrically released holding brake supplies 30 Nm of static torque to secure vertical loads when power is removed. The housing is rated IP65, which keeps out dust and resists water jets during washdown or machining operations. Continuous operation is permitted in ambient temperatures from 0 to 40 °C. Thermal endurance is classified as insulation class 155, so the winding conductors can withstand internal hot-spot temperatures up to 155 °C without loss of dielectric strength.

Feedback is provided by an optical single-turn encoder with 240° of connector rotation for convenient cable routing. It communicates through the EnDat2.1 digital interface and resolves rotor position into 2048 signal periods per revolution for fine commutation and stable control response. The winding code 0450 corresponds to the electrical variant used for drive sizing and matches the voltage, resistance, and current data used by the servo controller. Increased concentricity keeps the air gap uniform, which helps reduce cogging torque and vibration under dynamic loads, while the keyed shaft supports straightforward synchronous coupling alignment in multi-motor assemblies.
