I have an older (white with red logo) Haas HRT-210 with the brushless sigma 1 motor and very little use despite being a 12 year old unit.
Here’s the short version, I was getting servo overload alarm so I opened it up. The input shaft/worm gear on the rotary will turn very freely and smooth, but the servo motor shaft/pulley is very hard to turn by hand. Rotary was making a gravel mixer noise just before I got the alarm, so I presume the motor internals have grenaded.
I have the yaskawa part number right off the motor, SGM-08U2HA12. They’re all over eBay for like $500, can I just order a new one to drop in or is there anything special about the Haas part (at nearly $2k!)
Does the “O/N number” have any significance or do I just need to match the SGM-part number?
Will I need to swap the encoder I currently have or should any motor with that number have the correct encoder on its back?
As for swapping the pulley, induction heater and a gear puller are the first things to come to mind…
