Electric Fan Manufacturer

Electric Fan Manufacturer

An electric fan manufacturer is an entity that produces and sells electrical fans. These products are generally used in households to provide air circulation.

Around this time Gilbert also began offering fans in a larger 12″ and very rare 16″ model. These were also plug-in types. Unlike other early fans these models had a cast motor base rather than the stamped steel of the Roth and Eck.

HISTORY

In the 1950s, three pioneer HK electric fan makers – Shell, Din Wai and Wing Tat made Hong Kong a major player in global electric fans exports. The owners of these firms were active in local philanthropic activities and served on the Boards of Tung Wah, Shun Tak Foundation and Jardines Lookout Residents Association. They also made contributions to the HK & Kowloon Electric Trade Association and the Electrical Appliance Manufacturers’ Association.

Early in the 1890s a maker called Eck and another named Roth made small fans that were designed to be mounted on a vertical surface like a wall. These were more suitable for a train or ship than for a house. Some of these had carbon brushes while others used open field winding.

Around 1903 Philip Diehl patented a sort of “Lollipop” oscillating fan that had a stick in front of the blade. He sold or leased this patent to a firm in Springfield Ohio that made fans under the name Robbins and Myers. R&M grew to be an important company making hoists, cranes and wenches that were used in factories.

About 1914 R&M was making fans for DEMC and perhaps other companies. By the late teens, R&M had begun to make its own brand of fans under the name Dayfan which they offered to department stores. Later Dayfan was acquired by Delco which was the American division of General Motors at that time.

TECHNOLOGY

The electric fan is a mechanical device that moves air or other gases. It is one of the most basic electric inventions, but it is essential for human comfort and in some industrial applications. Fans generally deliver large quantities of low-pressure air. Blowers can deliver higher rates of medium pressure air. Compressors can deliver high-pressure air at a lower rate. An electric fan consists of three main components: the motor, the blades, and the structure that holds it all together.

The motor consists of copper wire coils that rotate when power is applied. It is attached to Air conditioner a rotating shaft, which in turn, drives the blades. The cage or housing holds the blades in place and protects users from accidental contact with the spinning blades. It also helps to direct the flow of the blown air.

When AC electricity flows through the fan it first reaches the capacitor and it delivers high energy to the stator windings. The stator windings are thousands of turns of conducting wire on any non-conducting structure like a coil and when they get energized they create rotating magnetic field which makes the rotor to rotate and in rotation the blades throw away the air nearby the fan.

The electric fan is necessary for many advanced technologies such as computers, lasers, large LED lights, petrol and electric automobiles and the space station and it would be difficult to imagine a world without them. But they are also important for everyday use and can save gigawatts of electricity in a country that is working to expand reliable energy access for its vast population.

DESIGN

The electric fan has blades that are powered by a motor. As motor technology has improved the size of fans has decreased. This is because the motors are now more efficient and use less electricity. The Edison Tech Center has a large selection of fans from all periods of electrical history.

The earliest electric fans had cotton or silk insulation around the copper wire windings in the motor. This was later replaced with enamel which allowed the windings to be twisted closer together, making them more compact and reducing the amount of copper needed. Older fans were made with heavy iron/steel bodies and cages designed to protect the expensive blades. Now, with the motor 80% smaller than in early models, modern electric fans have bodies that are more graceful and can be stopped by hand without risk of injury.

In a car, the electric fan can be used to distribute cool air throughout the living area. This can help keep the engine cooler and also evaporate perspiration which helps reduce the heat generated by the vehicle. In addition, the movement of air can help reduce the need to turn the thermostat up, thereby helping to cut fuel consumption.

An electric fan can also be used in a computer to blow cool air into cabinets where microchips Air conditioner distributor are located. This can help keep the chips from overheating and prevent them from frying.

MANUFACTURING

An electric fan is powered by an electric motor that converts electrical energy into mechanical energy that causes the blades to rotate and force air to move. The fan also has a housing that supports the motor and blades. The inner portion of the housing carries the motor stator winding while the outer portion carries the rotor which has thousands of tiny magnets that are in the shape of half circles and can be either concealed or prominently exposed depending on the design.

Most electric fans are a self standing model where the motor driven fan blades are mounted on a shaft that extends upright from a base or stand. These models often have a decorative, hollow, cylindrical shaft that is a pole or stick type structure that may be oscillatory although it need not be. The shaft and base are supported by a decorative grill or cover that gives the fan stability so that it generally stays aimed in one direction.

These fans are normally configured to be broken down into three distinct units namely the fan module, the shaft and the base for packaging, shipping and storage purposes. They are then reconfigured into the assembled configuration for use. A pull-chain is typically provided that allows the user to control the fan’s variable speed. Some of these fans also include a separate light kit which can be wired to the pull chain so that the fan and light can be controlled with a single chain.
