Hitec coreless servo
Hi, i am new on coreless digital servo. May I know what the different between coreless digital and digital servo? I do owned few digital servo and I can hear clicking sound when i try to put some load on it but this coreless servo the clicking look noisy then my digital servo, is that normal for a coreless servo act like this?? Thanks.

Better then normal digital servo? How was the power comsuption between cordless and normal digital?
#6
its a cordless motor in the servo thats what futaba says aleast
as for the buzzing noise its normal but it should stop after 1sec or so but its fine , as for power compusion it doesnt seem to bad actually maybe cause it has a cordless motor it has less residence

my is keep buzz, i put it on throttle and maybe the resistance that keep pushing the carb close that casue keep buzzing, what you think?
#8
do u have a small gap on the throttle linkage where the collar is at
my does it when im at netual but soon as i push the trottle spring back it stops i just have to take a other coil off then it shuld stop

Coreless refers to the rotor or winding type. The rotor in non-coreless uses copper or steel whereas a coreless (or ironless) motor can use aluminum or lighter mass material. Coreless motors are faster and more efficient (from less friction or cogging) but draw more power and run hotter.
I had to look this up.

Take a 27t stock motor, look inside. See how the windings are attached to a steel armature made up of stacked steel plates called a lamination stack.
Coreless motors don't have that. They use a basket weave of wire that deosn't need support the way standard winds do. So they are lighter and have less rotational inertia giving them faster response.
At least thats what it looked like to me on the motors I've seen. (not servos though)
Just stick to Hitecs 7955, 7950, 7940 and you don't have to think about these things anymore.
You could call a brushless servo motor cordless. It has no cords or bushes contacting its rotor........

by the way, if a servo is looking for center and we prevent it to center like on throttle do it able to kill the servo?
#13
the servo should center when u let of the throttle ,not sure if you dont let it center when your throttle it will kill it but u do what a gap inbeween the collar and the spring.your spring might be to stiff i wouldcheck that that will put a load on the servo

Ok....I wll try to make the servo as less load as I can. I might try to cut off some of the spring. Thanks.

one spring at a time though and test it out everytime not to much cause itwill be too soft
