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 […]

2 Simple Bidirectional Motor Controller Circuits Explored
A circuit which allows a connected motor to operate in clockwise and anticlockwise directions through alternate input triggers is called a bidirectional controller circuit. The first design below discusses a Full bridge or H bridge based Bidirectional motor controller circuit using the 4 opamps from the IC LM324. In the second article I have explained […]
Pump Motor Timer Circuit Diagram with Dry Run Protection
In this post I have explained about a circuit which can be used to monitor and detect the presence of municipal water supply by operating a pump motor through an intermittent ON/OFF timer. The timer keeps the pump motor ON for 15 seconds, if water is not detected, the pump is switched OFF for the […]
Treadmill Motor Speed Controller Circuit
In this post I have explained a simple, accurate, high torque treadmill motor speed controller circuit which may be effectively installed in similar units for acquiring PWM controlled variable speed feature. The idea was requested by Mr. Samuel. Technical Specifications I’ve a treadmill whose power failed completely…it had been imported from china and it’s like […]
Very Simple BLDC Motor Driver Circuits using Back EMF
In this post we investigate what’s a BLDC motor and subsequently I have explained regarding the design of a sensorless BLDC motor driver circuit. BLDC CPU Fans Seen those fast moving fans in CPUs, voltage stabilizers, DVD players, and other similar equipment, which work with utmost efficiency, consuming minimum space, current and yet are able […]
Stepper Motor Driver Circuit using IC 555
In this project we are going learn how to make a simple unipolar stepper motor driver circuit using 555 timer IC. Apart from 555 timer we also need IC CD 4017 which is a decade counter IC. By Ankit Negi Any unipolar motor can be connected to this circuit for performing specific task, though you […]
