I'm in the same boat. Needed a Z servo (brushed). Servo for a brand new machine $600, servo for my old machine $3500 w/ core return. For that I could just about buy another old HAAS and strip the parts. I would if I had the space for it. Just ridiculous. Ended up sending mine for a rebuild somewhere in CA for $950, hoping that goes well.

I get that Haas has raised there prices on parts ,, But have you checked Fanuc or other controller prices ? The only cheap controller to work on is Fadal,
I've always had good luck with a local electric motor shop for that, it's just another DC motor to them, they know what to do.
One thing I've learned is to take the encoder off before I give it to them. They don't seem to appreciate how sensitive the encoders Haas used are to shock etc.
Before sending a brushed motor for repair you could save money and time by doing some servicing yourself.
mine was 100% roasted rotor/armature windings and I know my time is better spent making parts than rewinding motors.
It was cheaper to get it rewound and reworked than buy new?
I rather doubt that. I have bought parts for the brush servo drive boards, even older output IGBTs that are not stocked by the usual outlets for not much above prices for the later parts. I added a row of memory for about $35.A Tech told me lately that Haas jacked up the prices on older parts due to availability of components to build boards and such for older machines.
