Default RE: Throttle Spring vs Servo Current


ORIGINAL: acerc

Measure the current draw, neutral, half throw, full throw, of the servo without it being hooked to the throttle. Just curious as to what it draws empty.
I'd do it myself but I currently don't have a meter.
That would be the idle current shown in the first column ... nothing connected to the servo and that doesn't change with servo position. There is also no load, run current but I did not measure or record that. But as soon as the servo comes to a stop, that is idle current.

For the record, high torque servos can have a extremely high run current, even without a load. Many early (read that old) digital servos had a very high idle current but it should be noted how low the idle current is for the examples I tested. The oldest digital servo tested was the JR and it had the highest idle current.
