IR Decoder for Multi-Speed AC Motor Control Single-phase alternating current motors are typically found in household items such as fans, and their speed can be easily controlled when using several discrete windings for set speeds. In this article, we build a digital controller that allows users to control functions such as motor speed and operating time. This article also includes an infrared receiver circuit that… |

Construction and Operation of Direct Online Starter Circuit Direct Online Starter or DOL is a simple electromechanical system designed for switching and protection of Induction motors. We all know that motors consume electric power horribly and this high power consumption is the result of current drawn by the winding of the motor. So higher the current drawn by the motor, the higher will be the power… |

Cycloconverters – Types, Working and Applications Power supplies can be classified into two broad categories: AC power supply and DC power supply. Since only AC power can be generated economically, most electrical machines run on AC power. However, the standard voltage and frequency from generating stations may not suit certain industrial machines. This is where power electronic converters like inverters and cycloconverters… |
