Specs on the spindle motor?
Hello everyone,
After a million mistakes I learned from, I finished my first Table top CNC machine that I built from scratch and it works perfectly. Nevertheless, I am still a complete newbie.
Now I got the CNC bug, and I want to continue upgrading my creation. I recently purchased a chinese CNC spindle motor, and I would like to integrate it to the controller. I am currently using a HobbyCNC EZ board, which does its work just fine, but it does not have a spindle control output. I see a bunch of chinese made boards with a spindle controller output but I see that they only control low DC motors and the quality is far from being ok.
My motor is 110V, so I am looking for a controller board that can drive the steppers, control and drive the spindle motor.
Can I just use a regular on/off switch with a variable power supply to adjust speed?
Can I use a relay connected to a low DC spindle output to drive the AC motor?
Pictures of my little CNC monster to follow.
Thanks,
Gustavo

Specs:
2) Power: 1.5 KW
3) Voltage: 110V 1 phase
4) Frequency: 400 Hz
5) Speed: 8000-24000 R/min
6) Water Cooling
7) ER11(3.175mm,4mm,6mm) collet chuck
8) Runout off: less than 0.005mm
I believe that's a 3 phase spindle and you need a VFD to control it. I think the 1 phase is for the VFD? Do you have a link to it?
If it does use a VFD, you need a board that converts PWM to 0-10V for speed control, or use ModBus if the VFD supports it.

According to those specs, I would agree with Gerry, that would be a 3 phase motor driven by VFD, so it should have analogue control input, is this a Huanyang?
You can also use a remote manual speed pot, if that was part of your question?

First, I apologize for all these (very basic) questions. My knowledge of electronics is very limited! (I am a chemist, wrong career!)
I purchased on Ebay. This is the link:
1.5KW MORE PRECISE WATER-COOL SPINDLE MOTOR FOR ENGRAVING MILL&GRIND p4 | eBay
I purchased the US version (110V~220V?)
My question is what would be the easiest way to control de motor? Ideally, I would like to control it using Mach3, but I will settle with an independent controller.
In particular, what PWM should I use and where can I buy it? What I need to know is what components do I need to purchase to make it work (either integrated to a controller board or with a stand alone controller)?
First, you need a VFD to power the spindle, like this.
VARIABLE FREQUENCY DRIVE INVERTER VFD NEW 2HP 1.5KW 7A | eBay
The VFD converts the single phase into 3 phase, which is what that spindle is.
Most people here prefer to use a Hitachi VFD, rather than the Chinese, as the Chinese ones have been known to have problems (failures).
There are several ways to control the rpm and on/off. A lot of people prefer to use Modbus, as it doesn't need any parallel port pins. There is a thread at the Machsupport forum about controlling a VFD with Modbus, and there may be one here as well.
You can also use a board that converts PWM to 0-10V, like this one.

Wow, lots of nice things. I just saw this:
CNC4PC
According to what I read, this board (C33), will interface with Hobbycnc board and allow me to control spindle and pump through Mach3. Is this right?

Ok. I'll give that a try.
Thank you,
I am still tinkerning with the subject:
I've purchased this VFD 110V VARIABLE FREQUENCY DRIVE INVERTER VFD 1.5KW 2HP 7A | eBay
and I'm also exchanging the spindle motor that I have for smaller diameter one. My question is: given that my VFD is 110V / 1.5KW, should I also get a 1.5kW motor or 0.8kW? I'm just questioning the VFD's capacity to handle the wattage.
Thanks,
G
