Ceiling fans are built with a variety of different motors to fulfill different price, style, and performance requirements.  Smaller, less expensive motors are not capable of moving as much air and are not precision made so over time wobbles and noise can develop.  Larger high performance fan motors are designed to efficiently move the maximum amount of air and their precision manufacturing ensures a lifetime of dependable, quiet and stable performance.  Each motor may be appropriate for different situations, below is a list of the most common fan motor sizes and our recommendation of when they should be used.

DC Motor

Currently the most energy efficient, technologically advanced and quiet performing high performance motor available.  These motors operate using up to 75% less energy and generate more power, and therefore air movement than any other option. Operational cost savings could be as high as $70 per year depending upon usage.  It is the most expensive motor that is often combined with costly high styling for those who want only the very best.

K55 and XLP2000

An outstanding high performance motor that will have no noise or stability issues even with continuous use.  More expensive but well worth it for the precision crafted components and engineering.


Also very good motor with excellent air movement and no noise or stability issues over its lifetime.  A better option for 60” or longer blades.


A very good motor with excellent air movement and no noise or stability issues over its lifetime. A strong value, good for all rooms and usage levels.


An above average motor with good air movement that should be trouble free. It’s a reliable and economical solution. Although this is generally considered to be a mid-sized motor than delivers average performance, some companies like Casablanca and Hunter manufacturer their own 172mm motor that delivers exceptional performance which rivals that of other companies 188mm motors.


An average motor that will provide less air movement and may develop noise and balance issues over its lifetime.  Appropriate for projects that need an inexpensive fan.
