EC Plug Fan

Store them in a reasonable temperature environment
Electronically commutated motors have a generous storage temperature range, and you'll avoid premature fatique of the electronic components as long as you don’t store them in extreme heat or cold.

Check the operating temperature range
Make sure that the “worst case” conditions of your operating environment are within the operating temperature limits of the ECM. Some motors may not be rated to operate in extreme cold temperature conditions, such as -40°C, without the use of special low-temperature bearing grease and low-temperature rated electronic components.

Know your environment
EC plug fans can have IP (Ingress Protection) ratings ranging from IP00 (no protection vs. particulates or moisture) to IP68 (protection against dust and submersible in water) and anywhere in between.

Check your incoming power quality
EC motors have built-in electronics to convert the incoming AC mains power to a DC voltage. The acceptable upper and lower limit are usually specified on the data sheet. Electronics and power surges don't mix.

Make sure you have a “drip loop”
When installing an ECM outdoors or in areas of high moisture, make sure you have a proper “drip loop." This means making sure that the power cord into the motor is oriented so that gravity causes water droplets to run down the power cord to the ground rather than down the cord and into the motor area.

Use vibration isolation mounts if needed
If your ECM is installed in an application where it will experience frequent shock or vibration, consider using rubber isolation mounts to avoid vibration transmitted to the motor, which would potentially prematurely fatigue the bearing system.

Make sure your fan blade is properly balanced
A wobbly fan blade will tax the motors bearing system and lead to shorter motor lifetime. Ideally the motor and blade should be balanced as a complete system. If the motor and blade cannot be balanced as a system, use a fan blade that has been properly balanced.
