The Bosch Rexroth servo motor, MPN R911321939 (MSK075E-0300-NN-M2-UG0-RNNN), is a synchronous motor from the MSK series featuring natural convection cooling and a multiturn absolute optical encoder with a 2048-period resolution and EnDat2.1 interface. It delivers continuous torque of 23.0 Nm at standstill (100 K) and a maximum torque of 88.0 Nm, with a continuous current of 15.6 A and a maximum current of 63.9 A. The unit has a motor length code E, size 075, a plain shaft without a holding brake, increased concentricity design, and a winding inductivity of 4,460 mH. Electrical connection is via a rotatable (240°) encoder connector. The motor has IP65 protection, class F insulation, operates below 75 dB[A], and uses a brushless design with lifetime lubricated bearings.

Frequently Asked Questions

Does the MSK075E-0300-NN-M2-UG0-RNNN motor perform well under continuous-duty conditions?

Yes, it maintains stable output and efficient heat dissipation during extended operation. Its design ensures reliability in temperature-controlled, clean industrial environments.

How does the increased concentricity design of the MSK075E-0300-NN-M2-UG0-RNNN improve performance?

It reduces vibration and enhances torque uniformity during high-speed motion. This leads to smoother, more precise performance in automation systems.

Do the natural convection cooling features reduce maintenance needs?

Yes, natural convection removes the need for fans or liquid cooling systems. This results in quieter operation and minimal maintenance requirements.

What advantage does the EnDat 2.1 interface offer in the MSK075E-0300-NN-M2-UG0-RNNN?

EnDat 2.1 ensures secure, high-speed digital communication between motor and controller. It also supports diagnostics for predictive maintenance and reliability.

Why is an optical encoder used in the MSK075E-0300-NN-M2-UG0-RNNN motor?

Optical encoders provide high-resolution feedback and excellent signal clarity. This enables extremely accurate positioning in complex multi-axis systems.
