Servo Question

[Preston_Hall]

I am running Futaba 9202 sevos. The ones that I was using in my Crapshooter have weakened in power and are easily stalled. Mostly this weakness is in the rotational direction used for turning.

Can repeatedly stalling or getting close to stalling torque weaken a servo?

PS

The batteries, switch and receiver are fine.

Possibly, stalling out the servo drasticly increases the amperage. Having a high amperage inside the motor will damage the wires and comutators. Aspecially with hair thin wires wrapped inside the tiny servo.

I think you can eather burn out the servo pot and or strip the gears.

I dont think when you stall them, the amps going to the servos is much better for them eather. I have had great luck with the 3302 futaba servos for steering.

I know some times space is tight in a rigger but I have been really happy with them. I have went through alot of servos and these hold up.

I even have a 3302 for throttle, so if one goes bad, i carry one spair and can swap them out.

sounds like the motor brushes or commutators are worn out. are they coreless? I would think stalling could cause the motor to arc possibly causing premature wear and tear. definitely the servo motor is the weakness you're seeing, if the other stuff you said is covered. but it is odd if the torque loss is only in the one direction :huh:

I had a simular problem with a 9301 servo. I took the servo apart and found the drive disc that sets on the output shaft and fits inside the drive gear was cracked. I had a gear set handy and the drive disc was included. I did replace all of the gears and the problem was solved.
