Re: VESC Overheating ?

Dumb question perhaps, but have you verified the 80 deg C reading? That is "burn you" hot... If the board is barely warm, then you may have other issues. Following the BOM and schematic of the original VESC 4.xx, mine reads 40C at an ambient of 20C.... (I'm not sure why - I haven't trouble...

Re: Maximum (theoretical?) eRPM

Good point, and I had to check..... (trust but verify and all that....) I have a not-so-trusty tachometer and set the ERPM to 100k. Measured shaft speed was ~33k, so I think that verifies to 3 pole pairs, or 6 poles. If that's the case, then the "stock" VESC should be capable of 66,000 RPM...

Maximum (theoretical?) eRPM

Hi folks, I've taken some liberties with the original VESC 4.xx design to beef it up a bit and spun a new 4 layer board. Design Specs: Battery Voltage: 45 V Maximum Current: 320 Amps (for <10-25 seconds max) Motor: 6 pole, 1150KV winding Maximum RPM: 52,000 RPM, 310,000eRPM Now, here's my question.....
