Which motor is used in ceiling fan?

In conventional ceiling fans, single phase induction motor is used. These motors consume minimum power and hence, are also known as fractional kilowatt motors. A single phase induction motor requires only one power phase for operating. It converts the electrical energy from the power input into mechanical energy.

Which motor is used in ceiling fan AC or DC?

Most ceiling fans, as well as most household appliances, use AC motors, as AC is the type of current distributed by power companies. AC motors function by being connected directly to a power source.

Why DC motor is used in ceiling fan?

Advantages of Ceiling Fans with DC Motors

High Torque – Ceiling fans with DC motors create a higher torque, meaning greater initial power and less energy consumptions. DC motors consume 70% less energy than conventional ceiling fan motors. Greater Control – DC motors control six speeds settings and reverse function.

What is the best motor for a ceiling fan?


  • DC motors are the most energy efficient motors available in the industry.
  • Magnetic field is stationary, unlike AC motors.
  • Up to 300% more efficient than standard fans.
  • Most fans with this motor have six speeds instead of the standard three speeds.

Is DC motor used in ceiling fan?

The specific type of DC motor used in ceiling fans is a brushless DC motor (aka synchronous DC motor). A DC motor uses an internal array of magnets of opposing polarity. … This process requires less electrical energy, translating into a 70% or greater reduction in power consumption over standard AC motors.

What is difference between AC and DC?

Alternating Current (AC) is a type of electrical current, in which the direction of the flow of electrons switches back and forth at regular intervals or cycles. … Direct current (DC) is electrical current which flows consistently in one direction.

How do I know if my ceiling fan is AC or DC?

AC means alternating current and DC means direct current. The difference between the two is in how the motors handle the electrical current they receive from the wiring in your ceiling.

What is difference between DC and AC motor?

The most obvious difference is the type of current each motor turns into energy, alternating current in the case of AC motors, and direct current in the case of DC motors. AC motors are known for their increased power output and efficiency, while DC motors are prized for their speed control and output range.

Why capacitor is used in fan?

The capacitor is used not only to start the fan but also to make it spin. In simple words, the capacitor creates a magnetic flux (torque) which makes the fan rotate. Generally, two capacitors in parallel series are used in the ceiling fan. … In other words, a fan will have a single-phase induction motor in it.

Is DC motor better than AC motor?

AC motors are generally considered to be more powerful than DC motors because they can generate higher torque by using a more powerful current. However, DC motors are typically more efficient and make better use of their input energy.

How many types of motor are there?

Basic motors have been classified into three distinct types: AC motor, DC motor, and specialized motors.

What is inverter fan?

Inverter fan

Inverter motor or Inverter Technology motors are advanced BLDC motors. Inverter technology increases the durability of the motor, reduces motor noise & also doubles the efficiency of operation and saves on electricity and cost. Saves up to 50% electricity. Silent Operation.

What is DC inverter fan?

A DC, or direct current fan, uses a power source that is connected to a transformer. The transformer then converts the energy to direct current, or a one-way current. As a result, the quantity of power utilised is ultimately decreased.

Which current is used in fan?

A fan will either be powered using alternating current (AC) or direct current (DC), and each current has a different set of voltages (V). An alternating current fan will have a voltage rating above 100 such as 110V or 240V. In contrast, a direct current fan will have a lower voltage rating such as 5V or 48V.

How much HP is a ceiling fan?

Motor. The motors in ceiling fans range between 1/60 and 1/3 hp. A higher-power motor helps meet the demands put on the fan by the resistance of the blades. In other words, the greater the span and pitch, the more powerful a motor is needed.
