Can an Electric Motor Still Be Used After Being Soaked in Water?
1 Answers
It can only be used after passing insulation resistance tests. Below are the relevant details about electric motors: 1. Usage Requirements: After a motor gets soaked, its usability depends on factors like the duration of water exposure, drying time, and ventilation conditions. In any case, it must pass insulation resistance tests before reuse. The insulation resistance between phases and between each phase and the ground (motor casing) should exceed 5MΩ. Additionally, the motor bearings must be properly lubricated. 2. Drying Methods: Typically, the rotor can be removed, lubricated, and the motor casing (coils) dried using methods like infrared lamps or blowers. For larger motors, it's advisable to use reduced-voltage electrification (such as series connection with a welding machine) for drying.
