Spindles are generally covered up to 1 year after date of purchase. We do not repair them in house, but we do work with our manufacturer to replace defective units. Generally if you have a defective unit covered under warranty, we will issue a replacement.

what is the warranty period and do you repair these in house? 2.2 kW (kilowatt) Water Cooled Spindle with Inverter (VFD)

Absolutely. These spindles do not get bogged down under load like routers will. The speed is regulated and current will adjust with the load.

Is the "1.5 kW (kilowatt) Water Cooled Spindle with Inverter (VFD)" spindle speed regulated? (Will maintain its speed under load)

Our spindles have a runout of less than .0001 in, which includes that collets that we sell. If you use a collet from another manufacturer, we cannot guarantee this TIR (Total Indicated Runout) dimension.

The weight of the 2.2kW spindle without the VFD (variable frequency drive or inverter) is 11 lbs or 5 kg.

The 2.2kW spindle with the VFD is 15 lbs or 6.8 kg.

I am interested in buying the water cooled 2.2 KW spindle for $339, how much does it weigh?

I have not tried connecting a 110V spindle to a 220V VFD; however, the parameters in a 220V VFD do allow changes to the values for the spindle motor. If you do plan on connecting the 110V spindle to a 220V VFD, damages can occur, so I would not recommend it.

With that said, here is the output of an LLM:
Using a 220-volt VFD (Variable Frequency Drive) to run a 110-volt spindle is technically possible, but it requires careful setup to avoid damaging the spindle. Here's what you need to consider:

Check the VFD Specifications: Ensure that the VFD can be set up to output the correct voltage for your spindle. Many VFDs are capable of outputting variable voltages and can be configured via their programming settings to match the voltage requirements of the spindle.

Adjust the Output Voltage: You'll need to configure the VFD to output 110 volts to match your spindle. This is crucial because supplying 220 volts to a 110-volt spindle would likely damage it permanently. Check the VFD's manual for instructions on how to adjust the output voltage settings.

Set the Current Correctly: Besides voltage, make sure the output current does not exceed what your spindle can handle. The VFD should be configured to supply the current at the rating appropriate for the spindle’s power and voltage requirements.

Consult the Manuals: Always refer to the manuals of both the spindle and the VFD. These documents can provide specific guidance on compatibility and settings.

Consider Professional Installation: If you are not familiar with electrical systems or if the manuals do not provide clear guidance, it may be wise to hire a professional. This helps ensure that the setup is done safely and correctly.

By taking these steps, you can safely use a 220-volt VFD with your 110-volt spindle, ensuring it operates efficiently without risk of damage. Just be meticulous with the settings and when in doubt, consult with or hire a professional.

[77] I have a 110 volt 2.2kw water cooled spindle. Can I run it with a 220 volt VFD?

Our spindle VFD's, have a multitude of different connectors that can be used for different operations. There is a manual that comes with each VFD, and you can refer to page 11 for different functions and descriptions.

We currently have a PWM, working with our machine, however it is connected via USB, and setup through Mach 3.
Also if you may have misplaced or lost the manual here is a link to the pdf:

It is possible to control externally the 1.5kW Inverter (VFD) (220 Volt) with PWM so i can control the spindle rotation? Do you have the documentation? Thank you

Yes, you can use a 220 to 110 step down transformer to provide power to your 2.2kw VFD and spindle.

hi, would like to make a change on my order, i purchase this part 2.2kW Spindle with 220V Inverter $528.00, and would like to make it for 110 volts instead of 220v. please

If you are using a silicone tube with a 1/4” ID, it will fit the nipple of the 1.5kW spindle water connections measuring an OD of 0.31”. The silicone will stretch and you will need to use water or saliva to help the tube fit.

The tube ID being smaller than the nipple will help the seal prevent water from leaking.

Hi, I'm considering buying one of your 2.2 KW water cooled spindles. What is these spindles run out ?

From reading on the Hitachi WJ200-022SF VFD, it seems as it will work just fine with this VFD. However since we have not tried this cross match, I would carefully take each connection and setting into great consideration and detail on both the Hitachi recommendations for setup, as well as our spindles recommended setup.
Our spindles do not have a thermal couple temperature output.

Will your 2.5 KW spindle work with my Hitachi WJ200-022SF VFD and does it have a thermal couple temp output?

The type of wire that should be used between the spindle and the VFD (Variable Frequency Driver also called the inverter) should be of stranded type and we use between 18 and 16 AWG.

The total current is divided among the three coil wires, therefor a wire gauge of 16 should be sufficient.

Currently we use 20AWG 4 conductor.
