The 2.2Kw Chinese Spindles - Info, Setup and Advice + More

[Jonathan]

This one is cheaper.
As far as I can see it's just luck with the bearings. The sellers on ali-express will discuss them however, so it's possible to get better ones but you do pay for it. I got my spindle from the eBay seller 'solar.jean', which was the cheapest at the time with best offer saving about £20. Turns out it has 4 bearings (H7005C TN1-2RZ and 7002CTYN) and the two big ones are a matched pair with the V markings on the outer rings, so it looks like I got lucky. Bear in mind however that was a couple of years ago, and someone on the forum got one from the same seller a week after me and received a presumably different model as his didn't have any writing on the side.

Power supply: I've got 3 of the generic 2.2kW chionese VFDs and they all work fine. I know plenty of other people who have used them without problems.

Water pump: These spindle are pretty efficient as they're induction motors, so they don't require much water to cool them effectively. The main thing is to get a pump with enough 'head' so that it can lift the water high enough to get up the pipes. A fraction of a litre per minute is probably plenty for most people, especially since the vast majority of things will never draw anywhere near the rated power of the spindle. Your calculation is fine except the assumption of dissipating 2.2kW is not reasonable. The spindle is probably about 95% efficient at full load, so maybe 110W ---> 6.3l/hour for 15° rise. You shouldn't need to spend more than about £20 on a pump, for example:
SUBMERSIBLE WATER PUMP 2200 L/H AQUARIUM FISH TANK POND GARDEN 56W NEW UK AP5100 | eBay

Radiator: I don't have one, just a reasonable size reservoir is enough... so passive cooling.

Cable: CY 4-core cable, 0.75mm^2 or greater. Connect earth wire to spindle body and VFD. Also connect shielding just at VFD end.

Tubing: Just need cheap PVC tubing, 8mm if I recall correctly. Plenty of it on eBay.

Collets: Get a set off eBay in china. They're plenty good enough for these spindles as although the runout with these collets is slightly greater then high quality ones, the spindle runout is greater than the difference so it makes virtually no difference. Make sure the spindle you get is ER20, not anything smaller, otherwise you can't use 1/2" cutters which are common for wood router bits.

Here's some useful setup information for Haunyang VFD that I've collected and collated whilst on my internet travels.

NOTE: Always check these settings are applicable to your Haunyang VFD as there have been some design variances over the years.

VFD Manual:


General VFD setup:
Here's the correct settings for the Huanyang VFD that always seems to come with these kits.

PD013 - 8 MASTER RESET <<< DO THIS FIRST
PD005 - 400
PD004 - 400
PD003 - 400
PD006 - 2.5
PD007 - 1.20
PD008 - 220
PD009 - 15
PD011 - 120
PD014 - 1
PD015 - 1
PD072 - 400.00
PD143 - 2
PD142 - 7
PD144 - 3000, factory setting is 1440 ->3000 gives correct RPM of 24000 at 400hz

Control Settings:
For spindle Start/Stop using Mach controlled relay connect DCM to FOR with the relay wired between the two. NOTE: Wiring DCM to REV will give reverse spindle rotation.

For variable speed control using a 10k ohm pot connect ACM and 10v to the pot with IV on the Wiper.

PD001 - 0 = Start from VFD Panel(Manual control), 1 = Control from inputs(use if Mach is start/stopping your spindle as explained above)
PD044 - 2
PD045 - 3

Spindle end wiring diagram:
(Pins are numerically marked on the inside of the plug, check by taking the 3 hex bolts out the spindle top cap. Whilst your in there take a ground from pin 4 to one of the 3 bolts inside that holds the bearing cap)


VFD end wiring diagram:
Live = R, Neutral = T, Earth = E.

Quick note:

Its a bit of a crap shoot with the cheapest VFD suppliers. Sometimes you get decent bearings, sometimes less so. Sometimes you only get 2 bearings, sometimes 4. Main problem is the quality control with the Haunyang VFD. Some last years, others are dead straight out the box or only last a short while. If your unlucky and get a faulty one don't bother trying your luck again by replacing it with another Haunyang, get an Hitachi X200 VFD instead. These are pretty much faultless.

These chinese spindles might all look the same but there are quality differences so paying more might not be a bad thing. If you want cheap as possible you usually get what you pay for and you'll be taking pot luck. Problem is how to guarantee a decent unit? Well I bought this.

Spindle Motor 3 Phase 2.2KW Water cooled ER20 with Matching VFD

Its tested and comes with decent bearings and 4 of 'em instead of 2. You also get a UK warranty should anything go wrong! Downside is its about £100 more than the cheapest chinese one's but it does remove all the question marks.

For any newbies like me reading this; dont worry too much about cooling. especially to start with. For example mine can run happily for say an hour without getting even remotely luke warm.. obviously if you plan on getting out of the box and doing some hardcore pocketing in ali then dont take my advice. But for those of you like me who have just built the machine and trying to get it all working. The cooling is just another complication you dont need.

I bought a cheap 12v caravan pump off ebay for £10 brand new. Ive been told not to worry about flow rate just to ensure there is a flow of water. The caravan pump can pump 10ft high in 1/4" hose without breaking a sweat.

Added all the info into the OP. Thanks!!

Hi Jonathan, thank you for this information which proves to be very useful to me. Can you please provide me with an example of the cable as I have tried googling it up and having no result? any help will be greatly appreciated. Many Thanks

This is the type of cable you need for the spindle http://www.csecables.com/acatalog/CY-Cable-4-Core.html 1mm or 1.5mm your choice. ..Clive

Hi Clive, the spindle has got 4 entries whereas the VFD has got 3 entries. Do i need to use the same cable for both connections? Also, should a power supply for the spindle be included in the package that I have bought?
