Q

In addition to tending to bearing lubrication issues, if a small electric motor is immersed in salt water, what should be done before placing it back into operation? washed in fresh water and thoroughly dried initially started with reduced voltage

🔍 Key Concepts

• Effects of salt water on electrical equipment and corrosion/contamination • Purpose of fresh water rinsing after salt water immersion • Why reduced voltage starting might be used on an electric motor after damage or questionable insulation

💭 Think About

• Think about what salt deposits and contaminants might do to the motor windings, terminals, and insulation if they dry in place. • Consider how you would minimize electrical stress on a motor whose insulation condition might be uncertain after being wet. • Ask yourself: which step(s) help remove salt and contaminants, and which step(s) help prevent damage if the insulation is weakened?

✅ Before You Answer

• Verify which action directly removes salt and conductive residues from the motor. • Verify which action reduces electrical and thermal stress on possibly weakened insulation during restart. • Check whether both, one, or neither step logically contribute to safely returning the motor to service after salt water immersion.
