Increasing Servo Voltage....What Fails First?

[Tommy R]

Hey y'all,

I'm trying to determine how much voltage I can safely run through a servo winch and I have some questions. Most run-of-the-mill servos are rated to 6.0v, but many people will increase that voltage and run 7v or more through them. It seems many people do this without failures, but for others they end up "letting out the smoke" the manufacturer so carefully packed in there. My question is this: When a servo fails/smokes due to too much voltage, what fails? Is it the board or the motor or what?

I'd like to run as much voltage as I can through my servo winch, but don't want to burn up the motor. I'll be using heyok's high voltage winch controller which replaces the stock servo board. It's rated to 9v! The servo I'll be using is either a 5955TG or a 5645MG.

Should I just stick with 6v and play it safe? Are these motors okay with 9v? Or should I try something in between? I'd hate to fry a servo (especially the 5955!) just experimenting so I'm hoping someone can shed some light on the topic. Thanks!!

When I had my 5645 on the pirate it was petty strong with the stock voltage.

I would just up the servo before messing with the voltage. Warranty Issues
