How to Maintain a Waterproof Electrical Motor


A water-resistant motor can be used in any situation where the motor may be exposed to moisture. If a motor is expected to be exposed to moisture, it may be necessary to install a water-resistant enclosure.

If you are having problems with your waterproof motor, here are some things that you can do to help:

Lubricate Correctly

When you lubricate an electrical motor, you need to know where the oil goes and what type of oil works best. You also need to make sure that the oil does not get into any electrical components that could cause an electric shock or short circuit. There are several types of oils used in electrical motors including vegetable oil, mineral oil, synthetic oils and silicone oils.

Use Quality Bearings for the Application

Bearing failure can ruin any electrical motor and cause costly repairs or replacement costs. Using quality bearings can help reduce these risks by ensuring that they last longer than cheaper alternatives. Bearings are typically made from stainless steel or brass alloys; both of these materials resist corrosion well and are suitable for use in industrial environments where there may be moisture present in the air or water on the floor or ground near where people work with electrical motors.

Prevent Bearing Failures

Bearing failures are the most common type of motor failure, so it’s important to prevent them by having your bearings replaced every year or two. If you notice any unusual vibrations in your pump or if the bearings feel loose, then it is best that you have them replaced immediately.

Monitor the Rotor and Stator Functions Regularly

As mentioned above, bearing failures are common among pumps. However, there are other components that need to be checked regularly as well. For instance, rotor and stator functions should be monitored on a regular basis so that they can be replaced before they cause problems with your pump’s operation.

Always check the motor mount conductivity

Over time, dust and other particles can get into your motor mount and cause it to fail. To prevent this from happening, you should always check your motor mount conductivity. You can do this by using a multimeter and testing for continuity between each pin on the plug. If there is no continuity, then you will need to replace your motor mount immediately before any damage occurs.

Clean Your Motor Regularly

The best way to ensure that your waterproof electric motor continues to function properly is regular cleaning. The dirtier your motor gets inside, the harder it is for air to circulate through it and cool it down properly. If you don’t clean it regularly, this buildup of dust and grime can cause overheating and permanent damage to your motor’s internal components. To avoid this problem, clean your electric motor at least once every two weeks by removing any dust or debris from inside with compressed air or a vacuum cleaner attachment. Be sure not to use any chemicals on the inside of your motor — they could damage its sensitive electronics or void its warranty (if applicable).


Of course, while waterproof motors can be incredibly useful, they also add a considerable amount of additional maintenance that you have to do to keep them working their best. If you’re not prepared for that extra burden, you may want to consider something else. So, if you have electrical motors that operate in water, they require an IP68 sealing box and waterproof material such as plastic resin to cover electrical motor. The best advice on how to do this properly is to work with a professional who specialises in making waterproof electrical motors.
