The most common and effective method of DC brushless motors motor waterproofing

Today’s waterproof small brushless DC motors that work up to 30 feet below the sea floor, which is a common industry standard, are named “waterproof,” not standard motors that have been modified, but truly waterproof motors, and they work well in deep water environments — in a variety of industrial and Marine environments.With redundant shaft seals, O-rings, sealed cable feed-through lines, pressure equalization, and other waterproofing features, the motor is designed to meet the needs of the design engineer without failure even after prolonged exposure to or immersion in most liquids.

Each strategy offers a different level of fluid protection when exploring waterproofing solutions.For example, some special cases just prevent splashing water, while others make the motor completely submerged, and have to reach a specific depth.Many waterproofing methods will restrict the air flow to the motor, which will negatively affect the maximum power output of the motor.The most common and effective methods of motor waterproofing are as follows:
Special housing: Covering the motor with a special housing is one of the most common ways to prevent water damage. Special housing can be expensive.
Waterproof shaft seals: protect the moving parts of the motor, especially the shaft and bearings. Waterproof shaft seals create an enclosed area for the internal work of the motor.
