The Bosch Rexroth MPN R911321788 (MSK100B-0450-NN-M1-BP1-NNNN) is a synchronous servomotor used within closed-loop control systems, integrating with a drive controller for regulated speed, torque, and position. It features an optical multiturn absolute encoder with 128 signal periods and Hiperface protocol, providing both absolute and incremental feedback over an eight-wire connection. The motor has a size 100, length B frame, a keyed shaft with seal, and includes an electrically-released 32 Nm holding brake. Cooling is primarily by natural convection but allows for optional fan integration. Electrical parameters include a winding code of 0450, 33.6 A continuous standstill current, 33.0 Nm continuous standstill torque, 110.7 A maximum current, 102.0 Nm maximum torque, and a winding inductivity of 2,200 mH.

Frequently Asked Questions

How does the encoder benefit the MSK100B-0450-NN-M1-BP1-NNNN’s motion control?

Its Hiperface multiturn encoder provides immediate angle recovery and stable feedback, ensuring reliable performance even after emergency halts.

Why is the brake essential in the MSK100B-0450-NN-M1-BP1-NNNN?

It secures the motor during downtime, preventing drift during maintenance or tool changes and enabling smooth restart afterward.

What role does steady current play in the MSK100B-0450-NN-M1-BP1-NNNN’s durability?

The consistent current flow maintains internal balance, reducing thermal fluctuations that could otherwise affect accuracy or lifespan.

How does the MSK100B-0450-NN-M1-BP1-NNNN ensure positional security?

It maintains torque hold through static phases, protecting calibration integrity during long dwell or inspection cycles.

How do the windings affect current behavior in the MSK100B-0450-NN-M1-BP1-NNNN?

The coil structure smooths current flow, providing quieter feedback and steadier torque under sensitive positioning operations.
