Sounds like a bearing freeze. I don't believe you will find oil ports on the motor.
All motors today are premanatly lubed from the factory.

Same deal as with WD40. It'll cleanses the bearing of what little oil is left on them.3 in 1, is a cleaning oil. It will cause teh motor to completely fail faster.
You are also risking that the motor spens slow, and causes your compressor to work harder, and run hotter. Causing it to fail.
And then you'll have an REAL expensive repair on your hands.
