Rexroth MSK040C-0450-NN-M1-UG0-NNNN Servo Motor 6000rpm No Brake

This MSK040C configuration is intended for controlled rotary motion in a machine axis using the 0450 winding and M1 feedback. Its brake-free construction is relevant to horizontal feed or positioning mechanisms where the machine does not require an integral motor holding brake. The plain shaft must match the installed coupling arrangement.

Application and Selection

Consider this configuration for small feed and positioning axes where the machine specification already calls for MSK040C-0450. 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.

The 0450 and 0600 versions share a frame designation but have different electrical data. Keep the winding code on the purchase order so a visually similar motor is not accepted as the same item.

Key Features

• 2.7 Nm continuous standstill torque at 60 K, with a separate 8.1 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.
• Brake-free configuration for installations that do not require an integral holding brake.

Supply and Inquiry Information

Request a quotation for MSK040C-0450-NN-M1-UG0-NNNN, material number R911320143. 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 0450 winding, M1 feedback and UG0 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 MSK040C-0450?

Use the full code MSK040C-0450-NN-M1-UG0-NNNN and reference R911320143. Include quantity, destination and required date. A clear nameplate photograph helps prevent a different encoder, winding or shaft option from being quoted.

Q2. Is the 0600 winding an equivalent replacement?

Not automatically. The 0450 winding has a 2.4 A standstill current at 60 K and a 6000 rpm maximum speed in the cited data. A different winding requires a drive, load and speed review, even when the mounting appears identical.

Q3. What evidence should I request for the UG0 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. Confirm that the offered unit is the brake-free version; do not approve a brake-equipped substitute without checking the revised assembly.

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 0450 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 R911320143 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.
