Question #: 14634

Question: what is the current draw of the 220v VFD

Current Solution

The current draw of the 220V VFD is 10 amps. Since the spindle is rated at 2.2kW, and the mains for the US 220V is in the range of 220V to 240V,

2200W/220V = 10A
2200W/240V = 9.167A

So, the rage of current draw will be between 10A and 9A, but it is advisable to provide a buffer of about 5 more amps if possible.

  • What are the physical dimensions of the 2.2kw VFD?

    On Monday, when I get back into the office, I will provide the dimensions for the 2.2kW spindle and I will also provide a drawing of these dimensions on the spindle 2.2kW page. Thanks.

    Additional Information:
    Spindle dimensional specifications:

    - Overall diameter is 80mm
    - The length of the outer housing is 200 mm
    - Diameter of the extension just below the spindle is 36mm and the length is 12mm
    - The Collet shaft diameter is 11.318 and the collet nut diameter is 16.75mm and both extend from the extension approximately 52.5 mm
    - The overall length is 264.5mm not including the air ports and the electrical connector (outer housing 200mm + extension 12mm + collet shaft and nut 52.5 mm).
    - The air ports extend 20 mm from the top of the spindle

  • What brand is the 2.2 kW spindle? Same for the VFD. Thanks.

    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 size of wire do you use to connect the VFD to the spindle?

    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.

  • What length of wire do you recommend for the black toe (2'x4') between the spindle and VFD?

    The length of the cable from the VFD (Variable Frequency Drive) to the actual spindle should be about the same as the z-axis cable from the z-axis motor to the z-axis driver which is recommended at 11 feet. This is locating the VFD about at the midpoint of the machine.

  • what size circuit breaker should I use with the 2.2KW VFD?

    The 2.2kW spindle has a power rating of 2.2kW or 2200 watts.

    If the VFD AC voltage input is rated for 220 volts, then 2200 watts / 220 volts is 10 amps, so a 15 or 20 amp breaker will work.

    If the VFD AC voltage input is rated for 110 volts, then 2200 watts / 110 volts is 20 amps, so a 25 or 30 amp breaker will work.
