Servo Motor seized again :( 2002 sante

[wakehead]

They say that Fluid Film is non conductive so should be okay i would hope. The guys above used WD 40 and it seemed to work great.

It sounds like they were using wd40 to loosen the bolts. I was worried about the fluid film igniting from a spark or internal heat (not sure how hard the PP motor works).

As you guys can see, even just the screws were rusted. If you look inside you can see lots of rust. I am not sure what spins inside. is the the small copper wires that all spin as one unit or is it literally just the center shaft. It is really seized on there bad

1) From this point can i just spray wd 40 all over it, or just down the main servo shaft. Will the wd-40 affect or damage anything? will the electronic parts still work okay covered in wd for a couple days?

Let me know what you guys recommend from this point and thanks.

Please don't use WD-40 ;-) I would go to a auto parts store, they should have electrical contact type cleaner that is designed for motors/generator.

I attached a picture from the web of an electric stepper motor that is disassembled. The center rotor (rotates) is what spins, the outer group of copper windings is the motor's stator (stationary part). Electricity is applied to the stator in phases creating a electromagnet with a north and south pole. The rotor, which is magnetized, will then turn to align itself with the north and south poles causing the shaft to move.

It does suck in that it looks like you have had significant amount of water/moisture in the motor and replacing it is just a temporary solution. you could really look to see where the water is coming from and try to divert the water away from soaking the motor. It may cost a few $ in sheet aluminum from Home Depot, but it may save you lots of $ in not having to buy motors.
