The circuit presented here is for a DC-CDI which are used in motorcycles. A DC-CDI is the one in which the high voltage (200-400VDC) is converted from 12V supply voltage. Researched and Submitted by: Abu-Hafss Studying the circuit, we see that it has two parts i.e. the smps CDI unit, enclosed in the pink box […]

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 […]
5 Simple DC Motor Speed Controller Circuits Explained
A circuit which enables a user to linearly control the speed of a connected motor by rotating an attached potentiometer is called a motor speed controller circuit. 5 easy to build speed controller circuits for DC motors are presented here, first one using MOSFET IRF540, second one using IC 555, the third concept with IC […]
L298N DC Motor Driver Module Explained
In this post I have explained about L298N dual H-bridge DC motor driver module which can be used to drive brushed DC motors and stepper motors with microcontrollers and ICs. Overview Modular circuit boards are best time savior for electronics designers which also reduce the prototyping errors. This is mostly preferred by programmers who write […]
DC Shunt Motor Controller Circuit using Variac
The simple DC shunt motor controller circuit presented in the following article uses a variac. This design facilitates an instant stopping of the motor at any stage with a flick of a switch, along with reversing the motor direction. It also provides speed control for the motor with a high level of accuracy. Overview TRIAC […]
Wireless DC Motor Speed Control Circuit
In this post I will show how to construct a wireless DC motor speed control circuit which can be controlled using any IR based remote controller. The proposed project has two main objectives; the first one is 5 step sequential speed control of a 12V DC motor using IC 555 (PWM) and controlling the PWM […]
