DC motor ceiling fans
The DC motor, running on direct current, is what separates today's ceiling fan from yesterday's. For comparable airflow it draws 5 to 30 W where an AC motor needs 50 to 100, about 70% less electricity. It vibrates less and goes down to very low speeds, the ones you keep on all night.

Every model in this selection is reversible: in winter, the reversed rotation pushes the warm air gathered under the ceiling back down at low speed. Six speeds on the remote control, from a barely noticeable breath to the full airflow of a living room.
Your questions, answered
What is the difference between a DC and an AC motor?+
The AC motor is simple, very robust and cheaper to buy. The DC motor uses about 70% less for comparable airflow, vibrates less and offers slower speeds. For daily or night-time use, DC is the one to choose.
How much does a DC ceiling fan consume?+
Between 5 and 30 W depending on the speed. Over a typical summer, 8 hours a day for 4 months, a 20 W DC motor uses about 19 kWh, around €5 of electricity.
Is a DC motor quieter?+
Yes, it vibrates less than an AC motor and holds very low speeds. It is the reference choice for a bedroom, where the fan runs at night.
