Variable frequency drive for high speed spindle

AI Thread Summary
The discussion focuses on the compatibility of a variable frequency drive (VFD) with a new high-speed spindle for a CNC router table. The current VFD, LS Industrial Systems - Starvert SV008IC5-1F, can handle up to 400Hz but is rated for a maximum output of 0.75kW, while the new spindle requires 1kW. Users suggest that the existing VFD may not be suitable for the new spindle due to this power discrepancy. It is recommended to consider upgrading to a larger model, such as the SV015IC5-1F, to ensure proper functionality. Understanding the specifications of both the VFD and spindle is crucial for optimal performance.

I operate a CNC router table with a high speed spindle. I'm looking to upgrade to a new spindle but need to know if the variable frequency drive I currently have will work with this new spindle.

The new spindle has the following stats: 300Hz, 1kw, 18000RPM.

The frequency drive is made by LS Industrial Systems - Starvert SV008IC5-1F

The info on their website suggests that this particular drive can reach 400HZ, but I’m not sure about the other details, especially whether or not 1kw is too high.

More info is available using this link:

Any advice would be welcome.

Cool to see another CNC person here, I've did my own X2 CNC Mill conversion recently.

The "008" of "SV008IC5-1F" says it's 0.75 kw time to upgrade to get those faster IPM speeds.

btw have you tried CNCzone.com before, people there are good at answering CNC stuffs like this.
 
I'm wondering if the 0.75KW motor rating - as shown in the PDF manual - relates to the motor within the frequency drive, and not it's output. Does anyone know if a frequency drive has a motor? My knowledge of these devices is quite poor.

The specs indicate the rating for the motor being driven. Looks like the model you are considering (SV008IC5-1F) would drive a 1 HP (0.75kW) load. If your spindle motor is rated at 1kW then I would consider something a little larger; maybe the SV015IC5-1F.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
