The R911324799 (MSK075E-0450-NN-M1-UG2-NNNN) is a Bosch Rexroth three-phase synchronous servomotor featuring a size code of 075 and natural convection cooling. It includes a rotatable 240° encoder connector utilizing the Hiperface interface, supporting multiturn absolute optical encoder technology with 128 signal periods. The servomotor has a plain shaft with pre-greased shaft seal, operates with a winding code 0450, and supports a continuous current at standstill of 15.6 A and torque of 23.0 Nm at 100 K. Maximum current is rated at 63.9 A and maximum torque at 88.0 Nm. Winding inductivity is 4,460 mH. The unit features a black RAL 9005 finish, a holding brake with 30 Nm torque, and is only compatible with gearboxes meeting Ex-protection under 94/9/EG. It achieves IP67 protection for connectors when properly connected, is designed for upright installation with the flange up, and supports a relative humidity range of 5% to 95%. Temperature is monitored by a single-channel system; compliance includes EN 60034-1 (thermal Class 155) and EN 60721-3-2 Class 2M1 transport conditions.

Frequently Asked Questions

What is the advantage of a rotatable 240° encoder connector in compact installations?

The adjustable connector orientation simplifies cable routing in tight enclosures. Flexible wiring reduces stress points and supports easier maintenance in dense machine layouts.

How does the plain shaft construction improve coupling alignment reliability?

Its cylindrical geometry allows direct connection with multiple hub designs. Uniform torque transfer minimizes backlash, improving overall mechanical accuracy during operation.

Why is the 0450 rated speed code suited for continuous process lines?

The 0450 speed range balances heat generation with torque stability. Sustained operation efficiency improves across repetitive load cycles and medium-speed manufacturing systems.

How does the MSK075E-0450-NN-M1-UG2-NNNN achieve reliable performance under thermal variations?

Natural convection with FN external cooling disperses internal heat efficiently. Continuous airflow stabilizes motor temperature and maintains torque precision during long-duration operation.

Why is a 30 Nm holding brake essential in heavy-load applications?

The electrically released brake secures the rotor under static conditions. Axis retention prevents positional drift, providing enhanced stability in suspended or vertical assemblies.
