What are the symptoms of water ingress in a tricycle motor?
1 Answers
There are three types of reactions when a motor is exposed to water. Visible faults: The motor fails to operate, and symptoms may include bearing damage, increased noise, severe coil burnout, and even a noticeable rubber burning smell. Hidden faults: Parts of the motor may rust extensively, leading to magnetic pole short circuits and reduced insulation performance of the coils. The motor's current will continuously increase, secondary faults will accumulate, and eventually, the motor will need replacement. Treatment methods: Remove the motor, dry it thoroughly (either by baking or sun-drying), eliminate rust, polish the rotor and stator with the finest sandpaper to prevent friction, and inspect the bearings.
