The idea was requested by Mr. Anwar Technical Specifications I am from Indonesia….. I Need Schematics For Incubator Timer with High Torque Motor (DC Motor Power Window in Car). I am trying […]
How to Make a 3 Phase VFD Circuit
The presented 3 phase VFD circuit (designed by me) can be used for controlling the speed of any three phase brushed AC motor or even a brushless AC motor. The idea was requested by Mr. Tom Using the VFD The proposed 3-phase VFD circuit can be universally applied for most 3-phase AC motors where the […]
3 Phase Brushless (BLDC) Motor Driver Circuit
In this post I have explained how to make a simple 3 phase brushless DC motor driver circuit. The circuit employs the popular IRS2330 3-phase driver IC The presented idea looks simple since most of the technicalities is taken care of efficiently by the IC itself, it’s all about connecting the relevant pinouts with the […]
How Brushless DC (BLDC) Motors Work
The post comprehensively details the basic operating concept of brushless DC motors also called BLDC motor. Difference Between Brushed and Brushless DC Motors In our traditional brushed motors brushes are employed in order to switch the central moving rotor with respect to the surrounding stationery permanent magnet stator. Brushes become imperative because the rotor is […]
