Model Forum / Radio Controlled / Land Models / September 2003Re: Re: (Question) Whats the difference between a 13 turn SINGLE and a 13 turn TRIPLE modified motor??? Please read within....
Thanks for the reply, just one more question, does the single use more battery power than the triple?? iam thinking of getting a Trinity D5 13x1 Mod Motor for a losi xxx Kinwald ed... iam going to use the standard spur gear and a size 22 pinion gear.... what does everyone think of this setup? any recommendations?? > Thanks for the reply, just one more question, does the single use > more battery power than the triple?? Slightly, yes. The single wind has more resistance than the triple wind, so it loses a little bit more energy as heat.

Surely it'll use slightly *less* power, as it'll draw less current (and also accelerate faster due to the slightly lower mass)? In practice, you really won't notice the difference in run-time (or probably even in characteristics) between a single, double or triple. Doubles are usually a good bet. The difference in turns *is* noticeable - certainly a two-turn step (e.g. 16 to 14, 14 to 12) will feel quite a bit quicker. HTH, Jonny > Surely it'll use slightly *less* power, as it'll draw less current (and > also accelerate faster due to the slightly lower mass)? ... Ah... yes, my original statement was poorly composed. _For the same speed_, the high-wind motor will draw less current than the single-wind motor, and less power. But the high-wind motor will have higher top speed (due to less resistance and more current around the armature), and it will use more power if you keep the hammer down. And it will probably draw more current (and power) during acceleration than the single-wind, because of the heavier armature. Personally, I use a 16-turn quint wind (5 winds!) in my RC10T3, and it's great. Smooth acceleration and good top speed. Rick R. That'll be pretty quick for a 2WD buggy. I have the same car, but I use a 14x2. The single might be a little too quick off the line for an offroad car that is that light. You'd want something that might have less tendancy for wheel spin for better hook up out of corners and stand-stills. |
