Novak GTB and KO 2123 Servo

[col300]

Hi,

Trying to connect the above... Connected everything as normal but just not sure about the blue FET wire from the servo. Do i just solder it to the positive battery lead on the ESC with the supplied resistor in between?

thanks in advance.

Hi col300, yeh just connect the blue fet wire to the battery+ with the choke(its not quite a resistor,but it does have a resistance) in between and connect the other bits the same way as any other servo.

How is it any different from a resistor?

ok thanks pugs, just wanted to check first.

Hi Huw333, a choke is different because it has a capacitence as well as a resitance and allows full flow of voltage without any voltage drop, it is in the fet wire to stop interference, cos the servo uses a amplifier circuit to drive the motor to make it faster!

I think you'll find it is an inductor.

And every electronic component has a resistance, capacitance and an inductance, it just depends what frequency the signal is

Well i've never heard of 'chokes' but i'm guessing that is just a general term. I have heard of inductors though - it makes sense to have one if there is an amplifier circuit as you say.

Hi g I think youll find it is called a choke, heres a quote from my old college textbook:.

The term choke is used when the inductor is designed to prevent a signal passing through the winding or when the coil is designed to reduce a particular waveform - such as ripple, as used in amplification process.

so in simple terms yes you are right it is an inductor but it is called a choke because it is used to smooth the signal to a product that uses an amplifier which is frequency sensitive.
