Awhile ago,someone pointed out that I forgot to include losses of the controller when calculating the efficiency % of power delivery to the motor from a battery .
My guts feeling response , without any research whatsoever was . " I hoped that efficiency was in the 92%-98% area and expected to be vary in relation to power delivery , expecting the 98% in the high power , the 92% in the low level region .
Was pleasantly informed by LinkOfHyrule
. They all seem to hover around 98% efficiency regardless of size
Very glad to hear this , however having designed in the past DC-DC converter of various type I remember that all circuit have a fixed loss which really play chaos on the efficiency of low power system .
Not knowing much about controller and having no time to research controller efficiency,would appreciate getting some numbers obtained from the many controllers used by the members of this site,even if the number come from the advertising brochure.
Very interested in the following specification , max power ( volts,amps,watts)and the efficiency at specifying level , like 20% or 50% or even optimum 100% .
Thank you for all your help .
