How to Select a Brushless DC Motor

Selecting the appropriate Brushless DC Motor requires knowing the requirements of the application, such as torque, speed, size, power, length, etc. While determining which Brushless DC Motor best fits the requirements, the controller must be considered as well, as this goes hand in hand with the operation of the Brushless DC Motor. 

Brushless DC Motor Applications

Instrumentation
Medical
Appliances
Automotive
Factory Automation Equipment
Aerospace
Military

Lifetime of a Brushless DC Motor

The Brushless DC Motor is often considered superior over the Brush DC Motor for its substantially longer lifespan. If run within the given specifications, the Brushless DC Motor can last over 20,000 operating hours based on bearing life. Running a Brushless DC Motor outside of its specifications shortens this lifespan.

NOTE:
Any failure to observe the aforementioned safety and environmental precautions violates the manufacturing standards and intended use of the Brushless DC Motor, as well as it will void the warranty.
