Hi Nomad, Sounds like you're drawing more amperage to run your servo then your voltage regulator and provide. There's a good chance you're going to burn it out. The servo you're running pulls up to 6 amps in a stall. You'll need a bigger boat (Jaws movie quote. LOL).

Here's my personal favorite. It's small, the output voltage is adjustable , input is variable up to 65 volts, has a 10amp MAX output and it's a switching regulator which means it will run cooler and be more efficient. It's a bit pricey and you'll also needs additional hardware to adjust the voltage through your computer but it's worth every cent. It's has 3 wires on the output side. You'll only need the two voltage wires so cut off ant tape the third one.

Since this is for an InMoov, you might want a 5v power supply with high amperage. Most people use that rather than batteries because there are so many servos.

DJ is dead on with his recommendation of using a 5 volt power supply with a high amp rating to run all your servos. As long as all your servos can run properly at 5 volts. Even though your hitec hs-805bb servo is rated at 6 volts (max) it will run nicely at 5 volts. It's rated to run between 4.8 - 6.0 Volts. When run at the lower end of the voltage range your servo will have less torque. This may not be an issue though.

hi averyone

robohappy i have allreddy bought all the servo's gail recomended . but i will have a look . thank you for the link .

hi dave

yeach one servo just dont move .  the voltage regulator will burn out for sure.

hi dj

a 5 volt power supply , you mean one that is plugged in a wallsocket ?

thank all

robohappy

you mean thisone ?
