Product Description:
The MSK071E-0450-NN-M1-UP1-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It combines compact dimensions with encoder-based feedback to support tightly controlled motion sequences on packaging lines, assembly cells, and material-handling gantries. As part of the manufacturer’s closed-loop motion platform, the unit converts controlled electrical input from an IndraDrive amplifier into precise mechanical rotation for positioning, indexing, and continuous-duty axes in industrial automation. Its feedback system allows the paired drive to track rotor position continuously during acceleration, deceleration, and low-speed holding.
Cooling relies on natural convection, so the housing dissipates heat without external fans or liquid circuits. Position feedback is exchanged over the Hiperface serial interface, and the optical scale delivers 128 signal periods per revolution to support precise velocity and position control. The stator winding uses code 0450, which indicates electrical values matched to standard IndraDrive current ratings. The motor has a size class of 071, which sets the flange pattern and shaft height for this frame. This arrangement supports compact installation where controlled motion and consistent feedback response are required.
The encoder stores absolute rotor angle across multiple turns through a multi-turn absolute design, so the drive retains position information after power cycling. A spring-applied, electrically released brake provides 23 Nm of holding torque for vertical axes or stopped loads. The extended housing identified by length code E adds stack length for higher continuous output without changing the mounting footprint. Torque is transmitted through a shaft with a keyway, which helps secure rigid couplings or pulleys against slip under dynamic load. The 240-degree rotatable connector simplifies cable routing in dense machines. Standard sealing and bearing arrangements support use in general industrial motion systems.
