ABB BSM90C-375CAX S3P346W081 3HAC040655-001 Servo Motor – IRB2600 MU100 Robot Drive Unit
When the servo motor on an ABB IRB2600 industrial robot fails, the entire production line stops. Weld cells go cold, assembly arms freeze mid-cycle, and every minute of downtime translates directly into lost output and escalating maintenance costs. The ABB BSM90C-375CAX (part number 3HAC040655-001, also referenced as 3HAC046598-001) is the OEM-specified servo motor for the IRB2600 robot’s wrist axes (Axis 4, 5, and 6), and there is no generic substitute that meets ABB’s motion-control tolerances.
Within the ABB MU100 drive unit family, the BSM90C-375CAX occupies the precision-wrist tier — engineered for the compact, high-speed articulation demands of the IRB2600 payload class (12–20 kg). The IRB2600 is one of ABB’s most widely deployed 6-axis robots globally, found in automotive body shops, electronics assembly, and general manufacturing. Sourcing a verified replacement for 3HAC040655-001 is a critical path item for any maintenance team operating this platform.

Frequently Asked Questions
Q: Is 3HAC040655-001 the same as 3HAC046598-001?
A: Both part numbers reference the BSM90C-375CAX motor used in the IRB2600 MU100 drive unit. 3HAC046598-001 is a later ABB catalog revision of the same assembly. Please confirm your robot’s serial number and axis when inquiring so we can verify the exact compatible revision.
Q: Can this motor be used on IRB2600 Axis 1, 2, or 3?
A: No. The BSM90C-375CAX is specified for the wrist axes (4, 5, 6). Axes 1–3 use larger frame motors with different part numbers. Contact us for the correct part for your axis.
Q: Do you supply the motor with the resolver/encoder cable?
A: The motor is supplied as a standalone unit. Resolver cables and SMB units are available separately — please specify your requirements in your RFQ.
Q: What is the lead time for this part?
A: Lead time depends on stock availability at the time of inquiry. In-stock units typically ship within 2–3 business days. Contact us for current availability.
Q: Do you accept returns or offer a warranty?
A: Warranty and return terms vary by condition grade. All terms are stated on the proforma invoice prior to payment. We do not accept returns on electrical components that have been installed.
