Servo Motor Voltages: 12V vs. 14V Explained

[Mzzed]

TL;DR

12V servos using 14V in datasheet?

I would like to understand why servo motors often state they are a "12V servo" but then in the datasheet they will refer to tests and torque ratings at 14V? I'm assuming 14V is chosen due to common lipo battery voltages, but then why call it a 12V servo motor?

Can you please link to an example datasheet.

A 12V servo expects to operate on a minimum of 12V, and will have a long life. If you operate it at higher voltages it will operate proportionally faster and have a shorter life.

Lead acid batteries maintain 12 volts when loaded, but they have 14 volts while being charged.

Thanks, that makes sense. Here's what I was looking at previously (not exactly a datasheet):

"Voltage must be lower than 14V" 12V nominal and 14V is the max.
