Description
Product Introduction
REXROTH MHD093C-035-NG0-BA (R911273949) is a 3-phase permanent magnet synchronous servo motor in Bosch Rexroth’s legacy MHD series, originally developed by Indramat for high-dynamic motion control in CNC machine tools, printing presses, textile machinery, and packaging equipment.indramat-usa+1
This motor delivers 23 Nm continuous torque at 3000 rpm with natural convection cooling, features a fully sealed IP65 housing with lifetime-lubricated bearings, and uses a resolver for precise position feedback, making it a robust choice for harsh industrial environments where maintenance-free operation is critical.indramat-usa+1
Frequently Asked Questions
Q: Can I hot-swap the MHD093C-035-NG0-BA?
A: No. This is a high-power servo motor with resolver feedback; it is not designed for hot-swap replacement. You must de-energize the drive (e.g., HDS/HDD, DMA, or KDV/KDS) and wait for DC bus discharge before disconnecting motor cables and resolver to avoid arc flash, servo fault, or mechanical runaway.adegis+1
Q: Is the MHD093C-035-NG0-BA obsolete? Are there direct replacements?
A: Yes, the MHD series is effectively obsolete in new production. Direct replacements are other MHD093C-035 variants (e.g., MHD093C-035-NG0-AA, MHD093C-035-NG1-BA) or modern Bosch Rexroth MSK/MSM motors with compatible flange, shaft, and feedback, but verify winding code, torque constant, and resolver compatibility before swapping.rexroth-us+1
Q: Will I lose my machine program when replacing this motor?
A: No. The MHD093C-035-NG0-BA is a servo motor; it does not store control logic or parameters. Machine programs reside in the CNC/PLC and drive controllers. However, you must re-tune the servo loop (current, speed, position) after installation, and verify resolver offset alignment to avoid oscillation or following error.indramat-usa+1
Q: Are these units factory-new or refurbished?
A: Most available stock is New Surplus (original Rexroth packaging, never installed) or refurbished/reconditioned units with 12-month warranty. Genuine Bosch Rexroth factory-new MHD motors are rare. Request photos of packaging, nameplate data (R911273949), and resolver test reports for audit.ebay+1
Q: What warranty and lead time should I expect?
A: Refurbished units typically carry 12 months warranty; New Surplus may have 6–12 months. Lead times: in-stock units ship in 1–3 days, but export paperwork and customs can add 5–8 working days.
