If I'm not mistaken, you can buy up to 5-axis and do mill-turn, but the controllers aren't really meant to be "portable."

It simply works. Has its subtleties but once you know what you are doing, things fall into place. Deciphering portions of the manual was my biggest effort.

One of the first things I did when I put my virtual hands on the user manual was to look for a threading command. It does exist, examples are even provided, and the only thing needed, as expected, is...

Hello!

I am on the market to buy a standalone CNC controller for a lathe and I've identified a few products on Aliexpress. In particular, there is this 990TDb or 990TDc controller that appears to...

Thanks, Ray!

I couldn't find this info on the datasheet for the Torus Pro: what is the constant power range of the spindle?

Please, point me towards one.

Unfortunately, I don't think he was mistaken.



I've been looking like crazy for such a BLDC and so far, I haven't found any. If you know where they are, please let me know because I really want...

Here are some of my observations and info provided by the two Tormach gentleman at the Maker Faire:

1) Ignoring the enclosure, the machine itself is small as one would might expect (I'm comparing...

One just needs to read Wikipedia's "Inch" History section to realize that this unit has no place in a technologically advanced civilization. The only saving grace for the inch nowadays is that it was...

Some pics of Tormach at World Maker Faire. I'll post my observations tomorrow as I am too tired right now.

I feel your pain. Customary units suck and need to be put to rest. I find myself memorizing a bunch of fractional inches in millimeters and avoid having to deal with the archaic system.

Actually, I'm going. I'll let you know what I find out.

True, but in this case we have a constant torque motor that delivers ~60W at 1000 RPM! The motor and controller may very well be good quality but they are totally inappropriate for this particular...

Ray, I have my sights on a Baldor BSM90C-3250AF for my Sieg SX4 milling machine (id - Baldor.com). This thing is a PMSM and can be driven either as an AC or DC motor. What I like about it is that it...

There is no "above base speed" for the 440, max speed is the same as base speed. The thing is strictly constant torque.

EDIT:

I asked Tormach on Youtube, after they posted the promotional...

According to Tormach, spindle is constant torque. This means that at 1000 RPM, one gets less than 60W of power. Doesn't sound very appealing to me.

Is the machine still under warranty? Grizzly is supposed to replace the board free of charge, no?

It's looking good!

This might help:

I'm looking to buy more of these motors as I anticipate burning a few. So, if you have them and are interested in selling, let me know!

I am in the process of converting my Sieg SC8 lathe to CNC. I'll be using LinuxCNC with a MESA card and I will also have an encoder on the spindle. I'll let you - and evrybody else - know how that...

I could be wrong (I am often) but I suspect your tubular steel frame is going to ring like a bell. I am curious to see the final result, though.

I'm going to roll my own thing, starting with a 2KW ST eval board (STEVAL-IHM028V2). That's why I only need the motor. As there is a good chance of blowing something, I don't want to spend too much...

PM sent. Thanks!

How much do you want for the motor, including shipping (US ZIP code 20171)?

Would it be possible to take a picture of the motor nameplate?

Thanks!

I have no interest in the chinese controllers, only the motor itself. I'm not aware of any of those motors blowing up. The same cannot be said about the controllers, it seems.

A BLDC is just a permanent magnet synchronous motor in disguise, which is a 3-phase motor.

Hi, all!

Does anyone have a used spindle brushless DC motor used on Chinese mills/lathes for sale? If you, PM me, as I might be interested. BTW, I am in Virginia/USA.

Thanks!
