Electric Motor Maintenance

mercredi 20 mai 2015

Hi all, especially the sparkles,

I have a 1 hp electric motor which hadn't run for 30 years. It initially didn't start reliably. And when it did start it vibrated and was noisy.
The switch checks out ok. So supply wasn't a problem. Upon internal inspection, there was a lot of dust, some surface rust and a wasps nest. After cleaning this away the motor now starts reliably and runs smoothly.

my question is...

should I leave the motor as is or is there benefit in giving the contacts and brushes a light spray with CRC 2-26 or similar product to improve the motors life and reliability.

Just as a disclosure, I'm not an electrician, but mechanical aptitude is up there and I know enough to not not electrocute myself.

Thanks Geoff.
