    New VFD / Water Cooled Spindle Kit.

    I want to replace the router in my cnc with a VFD / water cooled spindle motor ER16 kit. Available power is 120VAC, 15A so I will get whatever KW is available for this power input. The ER16 is not a real requirement but since I have a complete set of ER16 collets I would like to use them if possible.

    Any suggestions of a similar kit you used and place you bought it from?

    Thanks

    Re: New VFD / Water Cooled Spindle Kit.

    I found a thread here and mastec54 recommend G-Penny for spindles/VFD. So I will search at that site to find what I need and come back if I have any questions.

    The power panel to the house is too far and no practical to run a 240VAC line to my garage so I have to stick to 110VAC.

    Re: New VFD / Water Cooled Spindle Kit.

    Is there a big difference between the HY or Fuling Inverters? I prefer the Fuling cause light color and compact size

    The biggest Kw spindle you can run with your 120v power supply is 1.5Kw and then it should be 20A

    Normally the Laundry / kitchen oven will have a 240v circuit unless you have Gas

    So, the sub-panel will have 240v supply and that is normally not far from the garage so check to see if there is a space for a 2-Pole Breaker and you could then have 240v supply to your garage

    HY is the best low cost VFD Drive

    Re: New VFD / Water Cooled Spindle Kit.

    Many thanks for your time mastec54,

    So I will stick to HY and forget about the Fuling inverter.

    Too bad the 1.5Kw takes 20A because my garage plugs are connected to a 15A branch.

    My 2 levels house has no basement so the ground floor is level with the street. The double garage on the ground floor is divided at the back to make a room the same width as the garage by about 8 feet deep and in there I have my workshop and the electrical panel is located there. I have the space in the panel for an extra breaker and it’s easy to rum a line from the panel to the garage but all walls / ceiling are gyprock and that’s the problem, I will have to break the gyprock to conceal the new wiring or perhaps I can run the new line inside an exposed conduit which we don’t like.

    I could change the 15A breaker with a 20A but the wiring to the plugs is only 14AWG

    So I guess I will have to settled for an 800W water cooled spindle with 1.5KW inverter which is not that bad for my needs, I only do hobby work.

    You can squeeze by with the 15A but may have it trip the Breaker when fully loaded, is the sub box 240v or just 120v how many wires are coming into it, remove the front panel and take a photo, 800w would work well on that power supply

    Re: New VFD / Water Cooled Spindle Kit.

    The “squeeze by with the 15A” is tempting but I wonder about the tripping the breaker as to how often. The cost also may be a factor as I didn’t check yet the cost difference between the 2.

    The attached shows the panel, it’s an I-T-E panel, the house was built in 1986. Can’t move the front panel now, I did that many years ago when I had to add breakers to update the electric heating system. Also noticed there is no space now for an extra breaker.

    Noticed at the G-Penny site their English is quite bad and I wonder how good the communications will be when I’m ready to place the order. When I select a kit and I click to change to power supply from 220 to 120 the pictures of the unit remain the same which is not good to me to assure that I will get the right unit. I plan to place the order in January since I will not do any work on the cnc before X-Mas

    That would be easy to add a 240v circuit to that panel or a 20A 120v if you had too, you could take the cable up the wall to the top go across the ceiling rafters and down the wall without too much trouble, if you do something like this, you would use a 4-wire cable then you can have 240v / 120v from the same supply which is what you want for a machine Power supply is you live in NA

    See if you can get a wire across the ceiling if you can't you aways fish some wire in the ceiling and walls with very minimal sheet rock removal normally a 2" hole is enough , there are some videos on how to fish electrical wires in walls Etc.

    Re: New VFD / Water Cooled Spindle Kit.

    Sound easy Mastec54 but it’s not, bottom line is if there is a need and will to do something it will be done and in my case I have neither one.

    When I moved to this house 25 years ago the garage/workshop was in a very sad shape and I had to remove all the ceiling gyprock and a lot of the walls gyprock to re wire everything and install proper lighting, plugs & plumbing. Now yes it is possible but in my age I will not even dream about it!

    In addition, I remember the rafters in the workshop room (where the panel is located) run in the east/west direction and spaced every 6” and it’s a nightmare to drill holes on them to pass a cable. Never understood why the rafters are spaced so close in that room, perhaps because that’s a corner of the house and I have no basement? In the garage the rafters run in the north/south direction and spaced like they should, every 16” c/c so there is no problem in the garage.

    If I had a basement where everything in the ceiling is exposed, we would not been talking about it.
