Voltage?

70oldsracer · 10-08-2018, 12:39 PM

Using a stock series motor with an upgraded controller, F/R switch and solenoid, how much difference will you see from going to 42 volts and then going from 42 volts to 48 volts?

16% and 33% , respectively, is what I always see posted

Both of your numbers are from 36 volts. He may not have meant it, but he said, "going from 42 volts to 48 volts".

Thanks for clarifying, I was being lazy.

Going from 36V to 42V = 16.7% gain in speed and torque. (6 / 36 = .167)
Going from 36V to 48V = 33.3% gain in speed and torque. (12 /36 = .333)

Going from 42V to 48V = 14.3% gain in speed and torque. (6 /42 = .143)

Thanks, that explains it perfectly.

Orangeman, Yurtle will catch you on stuff like that! I think he was a proof reader in another life. Been catching me on details for years.

Reviewed contracts in my former life, before retiring. One misplaced word can literally cost millions. Ask how I know, having fought and conceded a contract I didn't review.

Well, there you go. Thought I was being facetious but apparently not
