Waterproof DC Motor
Waterproof DC motor is a brushed motor that can work in wet or underwater environment. Normally, a brushed motor can only be used in dry environments since it contains holes that allow air to pass through for heat dissipation.
Gibbons offers waterproof brushless motors and ABB ACS355 drive packages that are dust-tight and resistant to powerful water jets. These units are also suitable for use with a variety of other submersible equipment.
Vent Holes
A motor that runs continuously generates enough heat through normal operation to keep its windings dry. But infrequent use causes wide fluctuations in the motor’s temperature, allowing condensation to form. Moisture accumulation can shorten the motor’s life. It can also interfere with electrical conductivity.
Whether your open-type motor is in an air-tight enclosure or not, it’s essential to give water a way out. You can do this by making sure the weep holes in your motor are positioned so that water entering the motor (whether from direct impingement or through an exchange of air saturated with moisture) drains away freely.
Make visual inspection a part of your preventive maintenance procedure. If the weep holes become clogged, the motor can no longer drain moisture. If the weep holes are positioned incorrectly, they may funnel rain, snow and other debris directly into the motor’s windings, shortening its life.
In some applications, you can reduce the effects of condensation by using an auxiliary heating device or system to warm the motor during nonoperating periods. This will cause the motor to generate more thermal energy for a given mechanical power output, reducing the internal temperature rise that could lead to condensation. You can also minimize the losses incurred when thermal energy is transferred to the surrounding environment by using a more effective design for the motor’s bearing and by maximizing the surface area on which it rests.
Bearing Under the End Cap
A waterproof motor is essential for applications that require an electric motor to work under water. The motor must be completely sealed to prevent water from leaking into the motor coils and damaging them. There are several ways to make an electric motor waterproof. The most common method is to cover it in a specialized case that prevents liquid from entering the motor. This is an effective solution but it is also costly.
Another way to make a motor waterproof is by using a moisture-proof bearing seal. Waterproof DC motor The seal keeps water out of the bearings and maintains a hermetic seal, preventing moisture from wicking into the motor coils. This method is very affordable and provides a great deal of protection for the motor.
NTN’s Sentinel Series is a line of corrosion-resistant mounted ball bearing products that are specifically designed for the harsh conditions of food and beverage production. These components are designed to fit into flanged bearing housings and provide an additional layer of protection from caustic chemicals, high-pressure washdown cycles, and fine particulate contaminants. The easy-to-install safety end caps enclose rotating components, reducing hazards for facility workers and meeting OSHA standards that mandate protection from exposed horizontal shafting. The end cap snaps into the adhesive-backed ring that is built into most flanged bearing housings. This system is simple to install and withstands harsh cleaning processes that are essential for maintaining food safety.
Screw Holes
The windings of the motor are completely encapsulated with a pliable coating of cured epoxy. The epoxy also covers the screw 60 which affixes the ground wire to the cylindrical casing. Likewise, the epoxy runs through the opening 22 and fills the space created by the damming effect of the duct seal 56.
This essentially seals the motor and prevents water from entering, but it’s not possible to keep every bit of moisture out. To extend the life of a waterproof motor, it’s essential to position weep holes so that any water that does enter (through direct impingement or through exchange of air saturated with dampness) can drain away freely.
Waterproof motors are commonly used in wet environments like washing machines or power tools, but they can be found everywhere from robotics to household appliances. In these applications, the motors are exposed to constant wet conditions and may be subjected to a high degree of humidity. To keep these motors running smoothly and efficiently, they need to be properly lubricated. It’s important to choose a lubricant that is specifically designed for electric motors. Additionally, it’s a good idea to regularly inspect the motor for signs of wear or damage that can cause problems down the line. By taking these precautions, a waterproof DC motor can be a long-lasting addition to any equipment.
Water Infiltration
Generally speaking, electric motors and water don’t mix very well. However, it is possible to create waterproof DC motors for use in a variety of applications. The most common method involves a special casing that can shield the motor from moisture and liquids. Specialized cases are quite expensive in the market, but they can provide outstanding underwater protection.
It is also possible to seal the motor’s wiring to prevent moisture from entering the windings of the motor. This will not only improve the performance of the motor, but it will also protect it from damage caused by water infiltration.
Waterproof brushless DC motors are the best choice for any marine application. They are designed to withstand regular exposure to water, whether in salt or freshwater environments. In addition, they can handle high loads and withstand vibration.
Creating a waterproof DC motor is not easy, and it will usually come at an additional cost that is prohibitive 12v waterproof motor wholesale for most applications. However, the extra costs will be well worth it for any application that requires a waterproof electric motor. Brushed DC motors are typically made of magnetic iron, which corrodes easily in the presence of moisture. The commutator, which reverses the current direction of the motor every half turn, is particularly prone to arcing in humid environments. Consequently, the motor’s lifespan is significantly reduced in such conditions.
