Hi,
I have a Leonardo board and I'm in the beginning stages of testing(noobe), attaching the servos,etc,
what power supply do I need, that will operate 6 of these servos at the same time. My project is going to be controlling the servos using a DAW/usbmidi
Kuman 17Kg 270 Degree Metal Gear Digital Servo:
● Newly designed digital servo with interior design and precision potentiometers.
● 100% 17kg torque, metal gear and double-axis servo motor.
● Pull and plug connections and servo wire.
● Dual-ball servo, means one is drive shaft and another is virtual axis (support function).
● 270 degree rotation, barely absent and dead zone.
Specification:
● Weight: 60g
● Size: 402040.5 mm
● Speed:0.16 sec/60°7.4V
● Locked-Rotor Torsion：15Kg.cm 6.6V; 17Kg.cm 7.4V
● Voltage: 6-7.4V
● Unload Current: 100mA
● Line Length: 30cm
Thanks, Matt
Pretty cool servo!
I googled it and found the manufacturers site but it did not list stall current for this servo.
I would guess that it is similar to a standard RC servo and budges 1A per servo.
thanks for the quick reply! vinceherman
I think this is it, I could be all wrong though!
● Locked-Rotor Torsion：15Kg.cm 6.6V; 17Kg.cm 7.4V
You need to know the stall current, as the servo draws that every time it starts up.
If you can't find a value for it, assume 1 Ampere/servo, so if all servos are moving at once, you need a 6 Ampere power supply.
Would this be too much power?
also 5v or 12v?
I read on this forum that its needs to be 5 to 10 times over the unload current 100ma, so yeah an amp per servo should cover it.
Those servos are intended to work from 6V to 7.4V so 5V is a bit low and 12V is way too high. The second 6V power supply looks better.
