Electric motor powder coating?

[drummerdimitri]

I have a brand new electric motor I bought to build a belt sander and would like to change its factory color of green to a light grey.

My question is this: Since the motor winding insulation is of class F, that means that the max winding temperature is 155C but the oven in which the motor has to be placed in after the coating process is of 200C.

The motor will be in there for about 15 minutes but I'm not sure if that's long enough for the wire temp to reach 155C or above.

Should I be concerned?

If so, would I be better off just spray painting over the existing paint?

Just use a good quality automotive paint and spray it on.

Spray bomb it and be done.

I would only consider PC if it were going to be used outside.

Thanks for the advice guys, guess I will just spray paint it instead.

Would it be better to sand blast the motor first to remove the old paint so that the new paint sticks better?

Custom by rustoleum,unless you want to take it completely apart.

In a week, when the motor is coated in schmutz, will you really care what color it is?

Scuff it up and shoot it,sand/glass beads do terrible things when they get in the wrong place.

Good point, however unfortunately my brain doesn't work that way.

Is your motor open or enclosed. Enclosed can be painted and you may need that to keep the dust out.

I feel your pain.

The best adhesion you’re going to get on the bare steel of the motor is whatever they used at the factory.

Skuff, prime, paint then wet sand to a high gloss.
