Product Description:

The MSK071E-0450-NN-M1-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. The unit converts drive commands into controlled torque and speed, allowing precise positioning for axes used in material handling, printing stations, and general factory automation. It is intended for use with compatible servo drives that regulate current, speed, and position in a closed loop. That arrangement lets the axis respond quickly to changing loads while keeping commanded motion profiles consistent during repeated cycles.

The motor relies on natural convection cooling, so heat is transferred through the housing fins without external blowers and the unit should be mounted where free airflow is available. Its feedback connector is rotatable through 240°, letting the plug align with cable routing and reducing strain at the connection point. Position data travel over the Hiperface protocol, which carries encoder information to the drive for closed-loop control. Resolution is refined to 128 signal periods per electrical cycle, and the sensing element is optical, which helps maintain repeatable feedback accuracy even at low speed. The servomotor is delivered without a holding brake, so static load retention must be provided by external clamping or drive torque. The motor has a standard design classification, and the frame uses length code E for a longer active stack and higher continuous output.

The encoder is multiturn absolute, storing mechanical revolution counts internally so the axis can retain position information after power loss without homing procedures. Frame size 071 sets the flange dimensions and bolt pattern used by MSK mounting kits. Torque is transmitted through a plain shaft that supports keyless clamp hubs where zero backlash is required. This shaft format is commonly used with friction-locking couplings in servo axes that need low backlash and accurate concentricity. Winding code 0450 sets the voltage constant and rated current expected by compatible IndraDrive amplifiers.
