- Hmm, interesting idea!
I suppose the logic says "yes" here?
Otmar, can you test? :-)
For example will the 10% "HF"-PWM >15kHz
+ a 50% VLF-PWM ( *very* low freq, maybe with up-down ramps) will it be
more range-efficient than a 5% HF-PWM @steady 100% =no "VLF-PWM" ?
I think so! :-)
I see the no load-consumtion,
the eff.% at a constant low speed in inner city driving probably shows a very
oversized motor for this kind of light duty = energy consumption at this low
speed can probably be inmproved with a much "harder" driving in semi-long
pulses +freewheeling.
look at the 60Volt page of this sheet:
http://agnimotors.com/119_Series_Performance_Graphs.pdf
20Amp = bad
100Amp = >90% Eff.
