How Electric Appliances Work
Electric appliances operate by use of an electrical motor. The motor receives electrical currents and, using an arrangement of wire winding, magnets and a rotating shaft, converts the electrical energy into mechanical energy capable of doing mechanical work. The range of electrical appliances is rather broad.
Depending in the function of the said appliance, motor shafts come with varying attachments; for instance the set of blades in a processor or a blender.
Electrical appliances are not exclusively intended for indoor usage. They are used both indoors and outdoors depending on the purpose that they serve. Outdoor electrical appliances include items such as weed trimmers, hedge trimmers, electrical chainsaws and leaf blowers. All of them have an electrical motor that has a shaft attached to a device that is specialized for the appliance’s intended purpose.
Cordless items running on rechargeable batteries come under the category as well. Cordless drills and weed trimmers that run on rechargeable batteries have motors running on electricity just like plugged appliances. However, the form of electricity is what we call DC, or direct current, as opposed to AC, or alternating current, as seen in typical wall outlets. The operation of the appliance remains same once the motor receives electricity.
A generator’s operating principle is the exact opposite of an electric motor. In case of a motor the incoming electrical energy is converted to motor energy. In a generator some other energy source such as combustion or rotation causes motion which in turn gets converted to electrical energy. However generators too come under the class of electrical appliances.
