I got my motor back yesterday as the rewinding shops cant work with such small diameter.

I pulled the core out of the spindle today, tried a bit of heat at home but heating didnt help as the...

I actually tried to contact the manufacturer of my spindle 'Chanzhou HuaJiang Electric Co., Ltd' as they have a website: http://www.huajiang.cn/english/pro.asp

I got the charts from HSMAdvisor and you are right, the data doesnt look right which is what I suspected in the first place. This means those generic machine profiles in HSMAdvisor are not useable or...

Roger,

Thanks for the tips, although I havent seen a growler in a shop for more than 20 years or so. I used to see them in shops repairing car alternators and starter motors. But not anymore as...

With regards to the power curve, I contacted a few sellers and they gave me the standard answer that they dont have such charts or data. Probably, they never bothered even testing their spindles from...

you are right about special tools needed to refurbish the spindle and...

Thanks for advice Russ.

i knew i was pushing it too far running it at low rpms but something else caught my attention and by the time i could smell that magical smoke the spindle was a rest in...

I dont know if this is any help: HSMAdvisor allows you to download a bunch of generic machine definitions for the common water cooled spindles (although probably the air cooled spindles will be very...

Hello Mactec54,

Its been almost an year since you tried to guide me on this. Thanks for pointing me in the right direction. Its never too late to say thanks. Life simply got in my way, lost my...

Hello Mactec54,

Thanks for your reply.

The BOB supports PWM output and the manual also states that the VFD cant be controlled directly via the BOB.

Hello CNCérs,

This will be my first post here and I am desperately trying to get some advice and experience for you all.
