Variable speed press drill

I went in Ottawa at Motortek they could get me from Techtop a motor and aVDF
Topdrive 20 Serie Micro drives Techtop Motor Premium 56 C Aluminium 1 HP 3Ph 5/8 shaft 4 pole
What do you think around $1000.00 plus they need to get a technical man to wire it.. The input will be 220 volt 1 phase Those guy fix up my motor for my lathe and I never have any problem's with that . I trust those guy.
 
I would like to install a little tach on the shaft or on the front pulley to see my RPM do you have a web site for this ?

Sounds very reasonable especially for brand new. Is that a VFD Rated motor? It's not required but would certainly help.

Is 1Hp enough for your needs? It would certainly be enough for me. But my drill press is probably smaller that yours. Based on the specs, your old motor is 2hp.

There are all sorts of little Arduino modules that can deliver the tachometer feature from a sensor on the rotating device.
Just search Arduino Tachometer. Here's one link.

I saw yesterday night a picture of my press drill and they say 3/4 HP motor so with a 1 HP 3Phase I might be good.

This another good source for motors and vfds.

Edit - just wanted to add that those tachs that @Rauce mentioned work very well. I have one on my lathe and am really happy with it. I find the green colour is easier on my eyes than the blue or red. I'm going to add one to my belt drive mill by mounting the magnet on the under side of the spindle pulley.

I would love more details. I had decided to wait till I have my head apart to do that. Maybe you know something that I don't! How will you get the sensor system in there?
 
If you were in Calgary I would give you a nice big motor and a VFD to go with it.
You can get a tachometer with display off aliexpress.

A suggestion - this tachometer is available in a few different model. Look for the one that accepts 120 VAC power, so you don't need to use a separate DC power supply.

I hadn’t realized that was an option now. I don’t remember seeing them before.

Every VFD I’ve had has a spot for DC out on the control terminals, not sure of the voltage but maybe a DC one of those tachs could be powered there?

Here’s a link to the AC tach: https://www.amazon.ca/gp/aw/d/B08THW2QNC/ref=ya_aw_od_pi?ie=UTF8&psc=1

The only real downside to these simple ones is that it’s a single pickup and less accurate at lower RPMs.

If you could put a photo of your mount that will be nice.
 
@Susquatch - my mill is an older KBC machine so there is lots of room to play with. I'll start a thread when I do the install.

I called TECO about this and they said the DC output is only good for 20mv.

@Marc Moreau - if you are meaning the tach install here are a couple of pics. It's running off a 220v wall wart.

P1010762.JPGTach_Pwr_Supply.JPG
The knob (pot) controls the speed from the VFD the little switch between the knob and the tach is on/off power to the tach.
The picture below shows the sensor and magnet position. I milled a flat spot in the collar and JB welded the magnet in place, the collar is held in place by three set screws.

I originally installed a Shumatech DRO-350 on mine and it has an input for a spindle sensor. Never did use it. Since it was belt drive the belt positions reported RPM accurately enough.
Now I have the AC Servo so I can set the Drive to display Motor RPM.
1673981201656.webp
Doesn't quite match spindle RPM because I wasn't good enough at machining to make the pulleys exactly the same size. However the quadrature encoder on the spindle is fed to LinuxCNC and it reports what it thinks is the RPM.
1673981245390.webp

I still have some issues there. I'm not sure I made my pulleys completely concentric either so the speed on the LinuxCNC display isn't as stable as I'd like while it's rock solid on the Servo Drive.
