Speed controller

[wingtip]

bought a speed controller for my alvin today (still need another one too) but you cant beat this for the price..

its called a Tazer19T from dynamite which is distributed from horizon...it has fwd and rev, weighs 1.8 oz , input voltage of 4.8-8.4vdc, peak current of 500amps, and bec 5v/1A@7.2v
all for
$29.99

not bad for the current rating..it doesnt say what continous it will handle but i imagine its up there if it will handle peaks of 500amps...

Hi Wingtip

I came across an

Hi Wingtip

I came across an ESC for a similar price that looked like a good deal as well http://store.yahoo.com/raidentech168/fuescelspcof.html
It is meant to be a clone of an MC330CR.

Something here I am unsure

Something here I am unsure of, how do you determine the number of turns in the motor? For example how many turns in a Mabuchi FC-130?? The specification for the motor doesn't tell me...

Thanks

i think a more important

i think a more important number is the Kv? i've never seen the terms "turns" or "winds" used for r/c motors except for those 540/550 sized modified motors.

how do you determine the

how do you determine the number of turns in the motor

That's how many times the wire is wound around each armature. The wire is connected to the commutator and wound 27 times (stock 500 motor) the armature and then connected back at the comm. This is done for each lobe of armaturs, some motors have 3 arms, others have 5 or 7. On a double 13 turn motor, the wire is connected to the com, wound on the armature 13 times; the wire is connected back to the comm, and then wound a second 13 times before being terminated on the com.

So how do I determine

So how do I determine the number of turns in the FC-130 for example??

If there is no specification

If there is no specification on the number of turns, you might have to sacrifice a motor. Tear it apart to get at the armature, and unwind the wire from one arm, counting the number of turns as you unwind. The R/C car guys, and the fast electric boaters, seem to be the guys most interested in the number of turns on a motor. Might have to check some of those sites.
