Product Description:

The MSK071E-0450-NN-S1-UP1-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. This motor provides closed-loop rotary actuation for positioning, feed, and auxiliary axes in automated machinery. By combining compact permanent-magnet construction with integrated feedback, it converts drive current from a compatible inverter into precise mechanical torque and speed for industrial motion sequences. Its compact form also makes it suitable for machines that need accurate axis control without adding unnecessary bulk.

The motor has a frame size of 071, which sets the mounting interface and housing diameter. Winding code 0450 identifies the stator’s electrical characteristics, including voltage constant and permissible current. Heat from the windings is removed through natural convection, eliminating forced-air hardware. An electrically released holding brake provides a peak restraining torque of 23 Nm to secure vertical or indexing loads when power is removed. Position sampling is handled by an optical encoder with 128 signal periods per revolution, supporting stable velocity control and fine interpolation. The E motor length increases the active stack length for higher continuous torque while keeping the overall design suitable for general-purpose use.

Feedback wiring uses the Hiperface digital protocol and passes through a rotatable connector that can be turned 240° to suit cable routing. The encoder is a single-turn type, so absolute position is reported within one mechanical revolution. Mechanical output is delivered through a shaft with keyway that mates with keyed couplings to reduce slip under cyclic loads. This arrangement helps when the motor is installed in tight spaces where connector orientation and secure torque transmission both matter.
