A ceiling fan is a popular electrical appliance for keeping the house cool in summer. It is an effective and simple utility device for comfort. You will find two main types of ceiling fans in the market: AC (alternating current) and DC (direct current) ceiling fans. Understanding the difference between these two options can help you make an informed decision when buying a ceiling fan. Let’s explore the main differences and benefits of AC vs DC ceiling fans so that you can choose the best one for your needs.
AC vs DC Ceiling Fan Motors : Understanding the Differences.
AC Fan Motors
DC Fan Motor
AC motors operate on alternating current. In this, the direction of the electric current changes periodically. This alternating current is supplied from a standard household electrical outlet.
DC motors use direct current, which has a unidirectional direction. To obtain direct current, a power adapter or converter is required which converts household alternating current into direct current. However, direct current is also obtained from solar panels or household batteries.
AC motors work on the principle of electromagnetic induction. Alternating current generates a rotating magnetic field in the motor to drive this ceiling fan. The design of the AC motor is very simple, and it has been continuously used in ceiling fans for decades.
DC motors work on the principle of electromechanical energy conversion. In this, the magnetic field generated by direct current drives the fan blades. The design of a DC motor is more complex than that of an AC motor, in which advanced electronics are used for efficient operation.
AC vs DC Ceiling Fan – Know the Difference
There are many differences between ac vs dc motor ceiling fan which are as follows.
Difference Between DC vs AC Ceiling Fan Based on Energy Efficiency
AC Ceiling Motor Fan
- ceiling AC fans have lower efficiency than direct current ceiling fans. AC fans require more wattage to produce the same performance as compared to DC fans. This results in higher energy consumption.
- Due to low efficiency, alternating current fans increase electricity bills. Due to high energy consumption, the household budget gets disturbed.
DC Ceiling Motor Fan
- DC fans have the best energy efficiency. They consume less power than Alternating current fan because direct current is more efficient at converting electrical energy into mechanical energy.
- Although DC ceiling fans may have a higher initial cost, the long-term savings on electricity can offset this expense.
