Ceiling Fan Motor Speed Rpm

At a glance this information helps you to gauge a ceiling fan s airflow and efficiency.

Ceiling fan motor speed rpm.

Non reversing ceiling fans are allowed to have slightly higher rpms. Added features of a designer ceiling fan. The higher the cfm the higher the air flow rate. 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.

Cfm is dependent on the blade shape pitch and length and fan motor speed capacity. If you install a ceiling fan without wiring it properly it may prove impossible to operate the fan without the light on and vice versa. If you are on the market for a high speed ceiling fan you are interested in high cfm performance. Good air delivery is identified at 205 230 cmm.

Airflow delivered by a ceiling fan is the rpm of the fan measured in cmm cubic meters per minute. Rather a hi speed fan will run at 380 390 rpm. Ceiling fan maximum rpm compared to actual rpms. This makes it easy to compare two or more fans of similar size.

But what cfm is best. Good cfm ranges from 4 000 to 5 000. I compiled the data on this page so that i could determine if there is room for improvement in ceiling. Best is over 6 000.

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. The cubic feet per minute better known as cfm is the air flow rate or the amount of air a fan can move. The data below is based on ceiling fans that have a reverse function. 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.

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. In order to control the fan s speed the fan needs its own system of wires separate from that of the lighting element. Better ranges from 5 000 to 6 000. Thinking of buying a 600 rpm ceiling fan for your house.

The motor speed of a ceiling fan is denoted in rpm revolution per minute. What is a dc motor ceiling fan and what are its benefits. The standard 1200 mm fan will run at a certain speed that provides 300 350 rpm. A ceiling fan s wiring is integral when it comes to controlling its speed.
