The electric motor for many modern ceiling fans is the "stack" motor designed by Emerson in the late 1970s. It is an energy efficient motor with a basic stator, rotor and flywheel. A direct drive ceiling fan has a motor with an inner core that is stationary and a shell that revolves around it. This is called a spinner or pancake motor. The fan blades attach to the shell. Direct drive motors are less expensive to manufacture but are prone to mechanical issues and noise. Higher scale fans feature skeletal motors with an open design for better motor ventilation and are larger than the direct-driven motors. This makes them more powerful and durable. There are belt-driven ceiling fans with electric motors for the nostalgic look.
Fan blades can be made of wood, metal, plastic or a high-density fiberboard. Most residential fans have four or five blades. There are even artistic blades of unique shapes and colors or patterns. The housings on the motor and switch are both cosmetic and protective. They conceal the delicate parts of the motor and switch plus keep dust and moisture away from these parts.
Most ceiling fans come with a light fixture or the option to add a light fixture. This enables the user to maintain the lighting option in the room and enjoy the benefits of the ceiling fan. Light fixtures can be simple bulbs with plain glass globes concealing them or chandelier in appearance. This gives a person the ability to mesh the ceiling fan into the home décor with ease.
