What are energy efficient motors

Energy efficient motors Energy efficient motors are motors in which improvements in the design are assimilated so as to increase the efficiency more than the standard motor. Design improvements in energy efficient motors mainly target reduction in

Electronic regulators

Energy conservation techniques in a fan, electronic regulators : Conventional fan regulators incorporated resistors in it for the speed control. Lesser amounts of current flows lesser amounts of current flow through fan and remaining passes through the

Classification of energy sources

Classification of energy sources can be as given below : Types of energy source Description Example Primary energy sources These are the sources which can be directly founds in nature or stored in nature and can be

Compact fluorescent lamp (CFL)

Low energy efficiency of incandescent lamps has made them to be replaced with some others energy efficient alternative. Compact fluorescent lamp is one such alternative which can replace almost any incandescent lamp. CFL consist of two parts:

Energy conservation in electrical motors

Energy costs continues to increase due to ever increasing global demand for energy. Industrial sector is awakening in order to reduce cost of production after the markets has the been opened up in early nineties. Decreased production

What is energy conservation

Energy conservation simply means to reduce the growth of energy consumption by avoiding unnecessary usage of energy. Conserving energy helps the planet and saves money—so why don’t more people make the effort to do it? Maybe they

Types of starters

Various types of starters are as follows: Stator resistance starter. Star delta starter. Autotransformer starting. Rotor resistance starters. Variable stator frequency starting. Stator resistance starter A starter resistance is connected in each line series with each phase

Comparison of Induction motor and DC motors

Parameter DC motors Induction motors Supply DC AC Maintenance Frequent Less frequent Speed Low High Size and weight Large Small Speed control Rheostatic control, field control Stator voltage control, stator frequency control. Applications Lathe machine,drilling and milling

Construction of 3-phase induction motor

Construction : Conversion of electrical power into mechanical power takes place in the rotating part of an electric motor. In A.C. motors, rotor receives electric power by induction in exactly the same way as the secondary of
