Product Description:
The MSK071D-0200-NN-M1-UG1-NN04 is an IndraDyn S synchronous servomotor supplied by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for closed-loop motion tasks on pick-and-place axes, feed drives, and conveyor positioning units. By delivering controlled torque and high-resolution feedback, the motor allows the connected drive controller to execute rapid starts, stops, and interpolated moves that are essential for modern automated machinery. This arrangement supports accurate speed regulation during frequent indexing cycles and helps the machine maintain repeatable axis response under changing loads.
Heat generated by the stator is removed through natural convection, so the unit can be mounted without external fans while still keeping winding temperature within safe limits. Position feedback travels over a Hiperface interface, and this digital protocol carries absolute multi-turn data while reducing cabling between the motor and the drive. Inside the encoder, an optical scale produces 128 signal periods, giving fine angular resolution for smooth velocity loops. An electrically released holding brake supplies 23 Nm of static torque, enabling the axis to remain fixed when power is removed. The housing is sealed to IP65, which prevents dust ingress and protects internal components against low-pressure water jets.
The mechanical interface uses a plain shaft, so couplings or pulleys can be press-fitted without keyways, which helps reduce backlash in precision assemblies. Reliable operation is permitted in ambient temperatures from 0 to 40 °C, matching the climate maintained inside most control cabinets. Class 155 insulation permits higher winding temperatures before thermal aging starts, providing extra margin during peak current bursts. The motor has size code 071, which indicates the stator diameter and flange pattern, while winding code 0200 identifies the electrical resistance and inductance values used when matching the motor with a suitable power module.
