Importance of Measuring Rated RPM Manually before Replacing Old Motors with a New One In today’s case study, we have a cement plant, where four dilution air fans (2 fans in each of the 2 units of the kiln) of 225 KW and 744 RPM is under operation. After five years of operation, one of the current motor (fan) was planned to be replaced with the spare motor which was there in the store for the last 4 -5 years. This was planned because the current… |

Current Divider Circuits Explained with Formula and Practical Hardware When designing an electronic circuit, there are lots of situations when a circuit requires different values of voltage and current sources. For example, when setting the preset voltage for an Op-Amp, it is very common to use a potential divider circuit to obtain the required voltage values. But what if we need a specific value of current? Similar to the voltage divider,… |

Voltage to Frequency Converter using AD654 A voltage-to-frequency converter (VFC) is an oscillator that outputs a square-wave, whose frequency is linearly proportional to its input voltage. The output square wave can be directly fed to a digital pin of a microcontroller to accurately measure the DC input voltage, which means the input voltage can be measured using 8051 or any other microcontroller which does not have… |
