Type of Motors used in Ceiling Fans

Single phase induction motor

Single phase induction motors (also known as split phase induction motor) are required in four blade ceiling fans due to their easy handling and also their simple design, low cost, and high efficiency. Single phase motor is the economical choice for both office and house spaces as thepower output of loaded supplies are small.

Working of Induction Motor

The Four Blade Ceiling fans typically work on induction motors that convert electric energy into mechanical energy. The current powers the motor and makes its way towards the coil which is wrapped around a metal base. While the current conducts through the wire, a magnetic field is generated which exerts force in a clockwise motion that converts electric energy into mechanical energy. For this action, the motor coil begins to rotate and the fan blades are inclined into a specific angle so that the fan doesn’t wobble in high speeds.

Remote Control Ceiling Fan

Today Companies like Atomberg, Havells and many other have designed such Fans which are controlled by Remote Sensors due to which the speed of the motors can be controlled automatically. Remote Control Ceiling Fans have made life easier since along with the speed, one can also turn the fan on or off without even moving from their position from anywhere inside a room.

Therefore, companies such as Havells, Atomberg, and Crompton are now selling the Four Blade Ceiling Fan which has very high-speed motor with an average high speed of 350 rpm. The RPMs allowed for any residential ceiling fan that can be installed on a ceiling less than 10 feet high are restricted by UL based on the thickness of the blades and the blade span.
