01:39 AM * rifraf wonders if is cold up there in the top half, we just had a stinker of a hot day
07:57 AM rue_mohr: yea
06:55 PM Tom_L: https://www.youtube.com/watch?v=wiRMdRi0LrI
08:35 PM rue_mohr: hey
08:35 PM rue_mohr: I got a medical treadmill from work
08:35 PM rue_mohr: it doesn't use a brushed DC motor
08:36 PM rue_mohr: it uses a 3 phase servo motor and ABB servocontroller
08:36 PM rue_mohr: a 230V one
08:36 PM rue_mohr: :/
08:36 PM rue_mohr: and it has a second motor to raise and lower the angle of the machine
08:36 PM rue_mohr: which uses a 230V AC motor :/
08:57 PM aandrew: nice. bet both of those are torquey as hell
09:00 PM rue_mohr: yea, big mechanics
09:00 PM rue_mohr: so, was the starship made of tax money or elon money?
09:02 PM aandrew: not sure if there is a difference
11:15 PM rifraf: rue_mohr sound great to use in AU
11:17 PM rifraf: but you just use another cheap VFD to run your 230v motor from your 110V or whatever it is
11:17 PM rifraf: but the ABB should have docs available
11:17 PM * rifraf is just loving new servo motor
11:18 PM rifraf: first time i could sit and polish for an hour without going nuts, motor quieter that the driver fan.
