Rexroth MSK060B-0300-NN-M1-UG1-NNNN Servo Motor 10Nm Brake 4800rpm

This B-length MSK060 combines the 0300 winding with a plain shaft, M1 feedback and a 10 Nm holding brake. It is a specific spare for a braked feed or positioning assembly whose original motor carries the same order code. The brake torque describes the holding component, not the motor continuous output torque.

Application and Selection

Consider this configuration for compact braked feed assemblies where the machine specification already calls for MSK060B-0300. For a new axis or a changed load, compare the required speed-torque envelope, acceleration cycle, cooling conditions and mechanical drawing before selection. The motor frame alone does not establish suitability.

Distinguish the 5 Nm motor standstill rating from the 10 Nm brake rating in procurement records. Treat them as two different selection fields instead of describing this as a 10 Nm servo motor.

Key Features

• 5 Nm continuous standstill torque at 60 K, with a separate 15 Nm maximum torque limit.
• Optical multiturn absolute Hiperface, 128 signal periods; the feedback variant is part of the complete order code.
• Plain shaft with shaft sealing ring; rotatable plug, 240 degrees.
• 10 Nm electrically released holding brake for the specified static holding function.

Supply and Inquiry Information

Request a quotation for MSK060B-0300-NN-M1-UG1-NNNN, material number R911307216. Send the required quantity, delivery country and postal code, preferred condition, and requested arrival date. For a breakdown replacement, attach readable photographs of the original nameplate, shaft and connectors, together with the machine and drive identification.

Ask the offer to confirm the 0300 winding, M1 feedback and UG1 configuration explicitly. The quotation should identify the actual offered unit, condition, price, delivery estimate and included items. Availability and commercial terms require confirmation for the specific request; the product description is not a stock reservation.

If cables, a coupling, a shaft key or inspection records are needed, list them separately in the RFQ. Request nameplate and condition photographs before order approval, and agree any functional-test evidence, packing requirements and warranty terms in writing.

Compatibility and Replacement Note

Match the complete motor code and material number first. Then check the mechanical interface, drive feedback support, winding data, brake circuit where fitted, cables and machine parameter set. An HCS or HMS designation alone does not establish compatibility. Any proposed alternative needs separate engineering approval and commissioning checks.

Buying and Replacement FAQ

Q1. What should I send to obtain a quote for MSK060B-0300?

Use the full code MSK060B-0300-NN-M1-UG1-NNNN and reference R911307216. Include quantity, destination and required date. A clear nameplate photograph helps prevent a different encoder, winding or shaft option from being quoted.

Q2. Is this a 10 Nm continuous-duty motor?

No. The motor continuous standstill torque is 5 Nm at 60 K. The separate 10 Nm figure is the holding-brake torque and must not be used as the motor output rating.

Q3. What evidence should I request for the UG1 configuration?

Ask for readable nameplate and connector photographs plus a shaft-end image. Confirm the plain shaft with shaft sealing ring and rotatable plug, 240 degrees. For this braked motor, request confirmation of the 10 Nm brake option and any agreed brake-test record.

Q4. Can my existing servo drive operate this replacement?

Provide the complete drive and control-section codes, firmware information and original motor details. The review must cover the 0300 winding and M1 feedback as well as cables and machine parameters. Do not approve a motor solely because both products belong to the same drive family.

Q5. Are connection cables and mechanical accessories included?

The model identifies the motor configuration, not a complete installation kit. Ask the quotation to list the motor, cables, coupling and any separate shaft key individually. For the plain shaft, check the existing coupling bore and clamping arrangement rather than assuming a coupling will be supplied.

Q6. How are availability, condition and delivery confirmed?

Request a written offer against R911307216 stating the full model, offered condition, quantity, delivery estimate and validity. Agree required photos or test evidence before payment. If the exact item is unavailable, require any alternative to be identified separately and reviewed before acceptance.
