I just checked with the datasheet of a current commercial spin welder.[0] The rpm's given on the datasheet are 500 to 2500. I think the author might have slightly exaggerated the capabilities of their 1970s toy for effect.

- kurthr 4y agoMaybe those are European decimal commas? I mean... it's a ludicrous number with artificial specificity so I just interpreted it as a kazillion. I doubt the motor was capable of 1000rpm and it certainly wouldn't be necessary.
- eCa 4y agoIf they were decimal commas there would only be one of them, same as with decimal dots. In other words, I agree with your kazillion interpretation…
- userbinator 4y agoBased on the size and shape of the tool I'm guessing it's a brushed DC motor, which in that size can easily achieve several kRPM --- unloaded, that is. When it's actually being used to do the work of melting the plastic, probably below 1kRPM.
