The Bosch Rexroth MPN R911321511 (MSK101D-0300-NN-M2-AG2-RNNN) is a synchronous servomotor featuring a plain shaft with sealing ring, a multiturn absolute optical encoder with EnDat 2.1 interface (2048 signal periods), and an electrically-released 70 Nm holding brake. Designed for high-performance automation, it provides 57.0 Nm continuous torque at standstill (100 K) with a maximum torque of 160.0 Nm. The housing meets DIN 42955 standards, features IP65 protection, and the power connection is on side A. The unit weighs approximately 43.8 kg, operates from 0 to 40°C, and utilizes natural convection cooling, with optional surface cooling for higher loads. Rated winding inductivity is 3,200 mH.

Frequently Asked Questions

How does the 2048-period optical encoder impact positioning and servo tuning?

It provides fine incremental signals for interpolation and absolute position reporting, enabling tight loops with low following error when the drive supports EnDat 2.1. Multiturn absolute feedback also eliminates homing moves after power loss.

What should I consider when installing this motor with natural-convection (FN) cooling?

Mount with fins and housing surfaces exposed to free air and avoid enclosing it tightly, or torque will derate. The MSK series offers multiple cooling options, and FN requires unobstructed airflow to meet published performance.

Is the holding brake suitable for dynamic stopping in emergency events?

It’s an electrically-released holding brake intended to secure a stopped axis; use controlled deceleration via the drive for motion stop. The brake’s torque rating is for holding at standstill, not repeated high-energy emergency braking.

How do I size the drive given the motor’s peak current capability?

Select a drive that can supply the specified peak current long enough for your move profile while staying within thermal limits; cable gauge and connector ratings must also match peak current. Drive vendors list peak-time envelopes for MSK motors to verify this.

What protection level should I plan for in washdown or dusty lines?

MSK motors are available with a high degree of protection (IP65), suitable for many industrial environments when mated connectors and seals are used. Verify your exact variant’s IP and sealing kit before specifying for washdown
