Hi,
I'd like to test my motor with a sine wave controller. In China the selection is huge and price range is attempting, but they all lack of specifications. Mainly I guess they are meant for normal size wheel, say 26" or above, but how about smaller wheel size like 12" wheel?, If there is a limit for sine wave output frequency, then with lower diameter wheels RPM would be very low.
I have no exp how they work in real, is there special controllers for different wheel sizes or are the controllers somehow adjustable for top speed based on the wheel size, so if I full throttle then for small wheel I could raise the output frequency and vice versa for bigger wheels to reach the top speed I'm after? Or is it based only for speed sensor output, so If I hit the limit the output freq cant go higher..? but then again how am I going to tell the controller what is my wheel size...hmm.
