Why Are There Generally Three Blades Each Making Angle Of 120 Degrees With Each Other In A Ceiling Fan?

The blades of a ceiling fan comprise sections which are either made of wood or of any other material which is suitable. These sections are substantially planar. They have to be maintained at angle which is more than 90 degrees. That is, the angles of the blades of a fan should not be at right angles to each other. This is because the angles of the blades of fan should be relative to the axis of the rotation of a fan motor so that it is able to effectuate the adequate movement of the air.

Two blades of a fan have a first side and a second side each. These are attached to the upper portion of the motor of the ceiling fan in such a way that they can rotate. Each of the blades of a ceiling fan has an appendage which corresponds to the novelty character (or cartoon character) on at least one of the two sides of the blades of a ceiling fan.
