What is an ODP motor?
Open Drip Proof (ODP) These motors used to be the standard. Now technicians are realizing the limitations of an open enclosure. This type of enclosure allows air to flow through the motor, so particulates are easily introduced. Bearings, rotors, and windings are open to contaminants that can cause a myriad of issues.
What is a conduction motor enclosure?
These enclosures are usually used on motors 10 HP or below because the heat produced by these motors can dissipate more easily than higher horsepower applications. The motors in these enclosures are usually designed with a low temp rise so a fan is not required. This is not an airtight motor enclosure, so it needs to be used in a clean air environment.
How does air come through a motor?
Air comes through an external fan at the end bell and blows over the motor, keeping the inside clean. The air in the motor recirculates and is cooled by heat transfer through the frame. These are now the standard for motor enclosures in most applications.
Does a motor enclosure have a fan?
This motor enclosure has no fan. It is used in applications where it already gets plenty of air, such as in the plenum of an AC/Heating system. This is a dust-tight enclosure.
What is an ODP motor enclosure?

What is an explosion proof motor?
Explosion proof motor categories are rather interesting. These motors are labeled for classes: Class 1 is gases and vapors, and Class 2 is combustible dust. Within those classifications, there are groups such as A, B, C, and D. Those groups identify the specific type of vapor or dust in which the motor is suitable to be applied.
What is AC motor?
AC electric motors used on fans typically consist of windings, bearings, and other internal mechanical parts. All those parts need to be enclosed by what's referred to as a frame, which serves a dual purpose. The frame protects the internal parts, but at the same time, it allows heat generated within the windings to be dissipated from the motor. Some motor frames also have external fins that are used to help dissipate the heat.
What is a belt drive motor?
This type of motor has an open frame that allows air to pass through the motor windings for ventilation. The openings on the top side of the motor are shielded and protected from anything that could drip into the motor at angles ranging from 0 to 15 degrees (from above). These would typically be used for belt drive fans in relatively clean environments. Oftentimes, the motor would have a secondary fan motor cover to provide additional protection.
What type of motor is used on industrial fans?
Types of AC Motors Commonly Used on Industrial/Commercial Fans. AC electric motors used on fans typically consist of windings, bearings, and other internal mechanical parts. All those parts need to be enclosed by what's referred to as a frame, which serves a dual purpose.
