The R911325554 (MSK050B-0450-NN-M1-UG1-NNNN) is an IndraDyn S synchronous servomotor from the MSK series. It features a plain shaft design, type 0450 winding, and motor size 050 with length B. Cooling is provided by natural convection. The motor achieves a maximum speed of 6000 min⁻¹, a standstill torque of 3 Nm (3.4 Nm at 100 K), and a maximum torque of 9 Nm. Standstill current is 2.8 A (3.2 A at 100 K), with a maximum current of 11.2 A. Winding inductivity is 33,600 mH and rotational inertia is 0.00028 kg·m². The built-in electrically-released holding brake provides 6 Nm of torque. The unit uses a rotatable encoder connector (240°), supports the Hiperface interface, and integrates an optical multiturn absolute encoder with 128 signal periods. Environmental ratings include IP67 protection, operation up to 40°C, and up to 1000 meters altitude. Power connection is via RLS1100 and encoder via RGS1000 connectors. Weight is approximately 4 kg.

Frequently Asked Questions

What is the benefit of the electrically-released holding brake in this motor?

The brake engages automatically when power is cut, preventing shaft movement. This feature enhances safety in vertical-axis applications.

Why is a multiturn absolute encoder preferred in this Bosch Rexroth motor?

The multiturn encoder retains position data even after power loss. This eliminates the need for homing cycles and saves time during restarts.

How does the natural convection cooling system improve durability?

The natural convection system eliminates the need for forced-air cooling. This reduces mechanical wear and extends operational lifespan in the MSK050B-0450-NN-M1-UG1-NNNN.

What role does maximum current of 11.2 A play in performance of MSK050B-0450-NN-M1-UG1-NNNN motor?

The maximum current of the MSK050B-0450-NN-M1-UG1-NNNN motor defines the short-term peak torque capability. This allows the motor to handle sudden load variations without performance drop.

How does Bosch Rexroth ensure reliability of the MSK050B-0450-NN-M1-UG1-NNNN motor?

The motor undergoes stringent quality checks including thermal stability tests. Its precise winding design ensures consistent torque across industrial duty cycles.
