Product Description:

The MSK071E-0450-NN-S2-UP0-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and delivered in the MSK IndraDyn S Synchronous Motors series. Sized in the 071 frame and built in the extended E length, this motor provides precise closed-loop rotation for servo axes in packaging machines, robotics, and CNC equipment. By integrating permanent magnets with stator windings, it converts inverter output into controllable torque, allowing drive systems to position loads accurately in high-cycle industrial processes. Its increased concentricity supports smooth velocity regulation during repeated acceleration and deceleration.

Heat is removed through natural convection, so no external fan or liquid circuit is required, and winding temperature remains within the Class 155 insulation limit. An optical encoder with the EnDat2.1 digital interface feeds position data to the drive, and its native resolution of 2048 signal periods supports fine interpolation for smooth motion. The housing carries an IP65 protection rating, blocking dust ingress and low-pressure water jets when the shaft seal is engaged. Reliable service is supported across an ambient range of 0 to 40 °C. A rotatable 240° encoder connector simplifies cable routing in tight control cabinets and helps reduce cable strain at the motor connection.

The winding code 0450 matches the motor to compatible drive settings for rated current and voltage. Mechanical coupling is provided by a shaft with a keyway, which locks pulleys or couplings against slip during rapid acceleration. The rotor position is tracked by a single-turn encoder, which is suitable for applications that reference a home position after each power cycle. Because the motor is supplied without a holding brake, static load retention must be handled by the drive or by external mechanics. This arrangement suits axes that do not need brake-assisted holding when power is removed.
