Why do ceiling fans get dusty if they’re always moving?
Ig this is because when fan blades move against the air, the fan blades gets charged due to the constant hitting of air. This attracts the oppositely charged dust particles to attract towards the fan blade.Hence the accumulation of dust. Hope you found it useful

The conventional ceiling fans use single phase powered split phase winding induction motors.

Induction motors are very particular about the voltage and frequency supplied to them.

Pure sine wave supply from a power grid or a Diesel Generator or a pure sine wave inverter maintains a constant voltage of 110 Volts AC RMS or 220 Volts AC RMS and a constant frequency of either 50 Hertz or 60 Hertz.

This is ideal for induction motors and they work normally.

However in case of conventional inverters like Square Wave, Trapezoidal Wave, Modified Sine Wave or Quasi Sine Wave, the voltage fluctuates a lot and the frequency fluctuates much more.

This results in excessive vibrations in the windings and reduced torque due to unstable voltage and frequency.

This is not at all healthy for the fan or any motorized device as the excessive current will be induced in the windings and excessive heating in the coils that will damage them and break them.

Thus, always get a pure sine wave inverter for any motorized device or inductive load otherwise it will result in permanent damage.

RMS means root-mean-square and it’s not something that bothers us in the field much but it’s mightily important when you’re doing design work. All sources that are constantly changing have an output that a device sees that is lower than the actual maximum output and in DC we can use PWM to achieve the same effect.

The RMS value for a sine wave is 70% of the maximum output. To get 230V RMS you actually need a peak of about 326V.

We can define RMS as giving the same heating equivalent of a source of DC. Earlier on I said it’s 70% of the peak, but there is a calculus answer.

The electric fan was one of the most important electric inventions of all time. The fan is a building block of other more advanced technologies. Fans are necessary in computers, lasers, large LED lights, petrol and electric automobiles, the space station and countless other things. The fan as used in HVAC systems allows humans to build giant or underground buildings. It would be hard to imagine a world without the electric fan!

The electric fan has blades similar to a water or steam turbine. A DC or AC motor drives a rotating shaft.  Sizes of fans have gotten much smaller and lighter over the years.  As engineers improved the electric motor and blade design they figured out how to get more performance out of a design that uses less copper and steel.
