Rexroth MSK100C-0300-NN-M1-BP0-NNNN Servo Motor 38Nm B-Side Keyway

The BP0 configuration combines a B-side power connector with a shaft keyway and no holding brake. It is a specific mechanical alternative to a plain-shaft MSK100C, not merely another name for the same motor. The 0300 winding and M1 feedback serve an existing controlled-motion axis when its electrical and mechanical requirements match.

Application and Selection

Consider this configuration for keyway-coupled machine feed axes where the machine specification already calls for MSK100C-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.

Request shaft and coupling photographs before accepting an offer. A keyway shaft and a plain shaft can require different coupling arrangements even when the frame and nominal torque match.

Key Features

• 38 Nm continuous standstill torque at 60 K, with a separate 148 Nm maximum torque limit.
• Optical multiturn absolute Hiperface, 128 signal periods; the feedback variant is part of the complete order code.
• Shaft with keyway and shaft sealing ring; power connector toward b-side.
• Brake-free configuration for installations that do not require an integral holding brake.

Supply and Inquiry Information

Request a quotation for MSK100C-0300-NN-M1-BP0-NNNN, material number R911311545. 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 BP0 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 MSK100C-0300?

Use the full code MSK100C-0300-NN-M1-BP0-NNNN and reference R911311545. Include quantity, destination and required date. A clear nameplate photograph helps prevent a different encoder, winding or shaft option from being quoted.

Q2. Is a BG0 plain-shaft version equivalent to BP0?

No. P specifies a shaft keyway; G specifies a plain shaft. Verify the coupling bore and fastening method. Also confirm whether a separate shaft key is included in the quoted delivery scope.

Q3. What evidence should I request for the BP0 configuration?

Ask for readable nameplate and connector photographs plus a shaft-end image. Confirm the shaft with keyway and shaft sealing ring and power connector toward b-side. 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 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 keyway shaft, confirm the key dimensions and delivery scope before ordering.

Q6. How are availability, condition and delivery confirmed?

Request a written offer against R911311545 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.
