Lenze makes the AC Tech SMVector frequency inverter, a variable frequency drive (VFD). It is a controller that regulates the frequency (hertz (Hz)). The faster the frequency, the faster the RPM’s of a motor. If an application does not require a motor to run at full speed, a variable frequency drive (VFD) can be used to ramp down the frequency and voltage, changing the load.
In the case of this loom a lower frequency allows the loom to run at a slower, more regulated speed.

Wiring a couple of fluorescent fixtures, installing them, picking up and cleaning after installing wiring the other day, and placing the loom where it will go took up most of the morning. A centre support beam needed to be moved to allow for adequate space while loading the sectional warping beam.
…boxes installed…joists drilled…wires run…wires staped…plugs wired…welder plug wired and hung…storage area breakers installed and connected and working(!)…controller screwed into place…to be completed next week…
In preparation for wiring the weaving shop the items for the weaving itself which had been placed on the shop cement needed to be moved. In order to get it out of the shop a roof had to be put on the shop. With that done and the seams sealed today we packed all of it (wool, cotton, and 500+ empty canning jars) – three containers at a time – on our Kubota’s loader and hoisted them up above. Material for stairs is already planed and cut, but there is no place in which to construct it. So today was the day. And here it is, the first of our materials stored safely, cleanly, securely, and protected.
Our sixteen years here has been like an octopus, starting projects here and there, working on them as we had opportunity and need. It may not seem like much, but starting to move this material into this area marks the completion of another stage, started years ago. It feels really good.
…cleaning the floor/ceiling of our weaving workshop, then applying roofing underlayment, and finally laying down rolled roofing (in white, which is all they had, but was great because it gives a bit more light up above)…I now need to seal the cracks with some heated asphalt sealant…tomorrow?…and then pour on the sand so that these sealed cracks will not stick to the weaving items and other things we will store up there…
Weaving involves integrating many aspects of care: yourself, others, tools, and ideas. Today I planed rough lumber for the weaving shop. Siding. There’s more to just throwing a switch on any tool…weaving loom or other. Every day the blades need to be correctly sharpened. We do that ourselves here. And you have to know your machine well enough as well as the composition of the wood to plane well…
A week ago I brought power into the shop as well. During down time in the field now we are again up and running ahead on finishing this project. Installing outlets and wiring is next.
