Ceiling Fan Motor Speed Rpm

Ul actually states the limitations based on the maximum allowed speed of the tip of the fan blade at 3200 feet minute for 3 16 thick blades and 2400 feet minute for 1 8 thick blades.

Ceiling fan motor speed rpm. Thinking of buying a 600 rpm ceiling fan for your house. Reiga 52 inch dc motor ceiling fan with light remote 3 oak color blade suit for indoor outdoor 6 speed 3 color temperature switch 4 3 out of 5 stars 140 199 97 199. A ceiling fan s wiring is integral when it comes to controlling its speed. The cubic feet per minute better known as cfm is the air flow rate or the amount of air a fan can move.

The motor speed of a ceiling fan is denoted in rpm revolution per minute. The higher the cfm the higher the air flow rate. Good air delivery is identified at 205 230 cmm. Although permanent magnet dc motors are also built with poles these poles don t impact speed like with ac motors because there are several other factors in play with dc motors.

Cfm is dependent on the blade shape pitch and length and fan motor speed capacity. Best is over 6 000. The standard 1200 mm fan will run at a certain speed that provides 300 350 rpm. But what cfm is best.

The data below is based on ceiling fans that have a reverse function. Better ranges from 5 000 to 6 000. While many ceiling fans have speed settings of three four levels a few variants of the fans can also go up to six levels of speed change. Non reversing ceiling fans are allowed to have slightly higher rpms.

Good cfm ranges from 4 000 to 5 000. Added features of a designer ceiling fan. I compiled the data on this page so that i could determine if there is room for improvement in ceiling. At a glance this information helps you to gauge a ceiling fan s airflow and efficiency.

What is a dc motor ceiling fan and what are its benefits. This page compares the actual rpm that each fan operates at on high speed compared to the maximum allowed rpm per government regulations based on the size of the fan and thickness of the blades. An exception to this rule of thumb would be a ceiling fan that runs using single phase ac motor but has three different speed settings. This makes it easy to compare two or more fans of similar size.

Airflow delivered by a ceiling fan is the rpm of the fan measured in cmm cubic meters per minute. Ceiling fan maximum rpm compared to actual rpms. Most of the designer fans come in colors like cherry oak walnut and rosewood. Rather a hi speed fan will run at 380 390 rpm.
