FANUC AC spindle motors
AC spindle motors for machining centres and lathes. The seller publishes this family at family level — no single motor number is named in the catalogue — so the page explains how a spindle motor inquiry is pinned down.
AC spindle motors
A spindle motor is the most machine-specific part in the drive chain: frame, cooling and feedback all follow the machine builder's design, and two machines with the same control can carry different spindle motors. The seller stocks the family and answers by number, so the ordering key is the label on the motor already fitted. Quote that number exactly, with the machine builder and model beside it, and the desk checks the motor shelf against the pair of them.
Because no catalogue number is named for this family, there are no detail pages under this one — the honest shape of the shelf. What the page can do is shorten the inquiry: the sections below cover the label information to copy, the amplifier pairing, and the bench route for a motor that has already failed.
| Label field | Where it appears | Why the desk asks for it |
|---|---|---|
| Part number | Rating plate on the motor body | Identifies the exact motor variant, not just the motor family |
| Amplifier pairing | The spindle amplifier in the same cabinet | Motor and amplifier are matched as a pair; one without the other cannot be confirmed |
| Machine and control | The machine plate and control screen | Confirms the generation and frame the motor serves |
| Fault description | Your message | Separates a motor fault from an amplifier fault before anything is shipped |
What to copy from the motor label
Three lines from the label and one from the machine plate give the desk what it needs.
- The complete motor part number, including suffixes after the B-code
- The motor's series marking as printed, where the label carries one
- The machine builder and model the motor is fitted to
- The matching spindle amplifier number, if the amplifier label is reachable
The amplifier pairing
Spindle motors and spindle amplifiers are bought as a chain even when only one link has failed. A motor inquiry that also quotes the amplifier number — the A06B-6222-H022 and A06B-6140-H015 are the catalogue's named spindle modules — lets the desk confirm the pairing instead of assuming it. Where the amplifier is the failed link, its detail pages carry the identity and condition information for those numbers.
Failed spindle motors and the bench
A spindle motor that trips its amplifier, runs hot or has lost its smoothness is a bench question as much as a shelf question. The repair service accepts the same families the catalogue sells, and the test bench diagnosis separates a motor fault from an amplifier fault before money is committed to either. Send the symptom with the numbers; a one-line fault description saves a round of questions.
