In this post I have explained a universal ESC circuit or an electronic speed controller circuit which can be universally applied for controlling any type 3 phase BLDC or even an alternator motor. What is an ESC An ESC or electronic speed controller is an electronic circuit which is normally used for operating and controlling […]

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 […]
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 […]
BLDC Ceiling Fan Circuit for Power Saving
Within the next few years we may find all conventional capacitor-start type of ceiling fans getting replaced with BLDC ceiling fan circuits, since the concept allows the operation to be extremely efficient and save power by more than 50%. Replacing Capacitor Start Fan with BLDC Fan Just as the traditional incandescent lamps today are almost […]
High Current Sensorless BLDC Motor Controller using Back EMF
In this post I have explained a high current sensorless BLDC motor controller circuit which does not depend on hall effect sensors for initiating the operations rather utilizes the back EMF from the motor for the sequential input Overview For proper commutation most 3-phase BLDC driver circuits rely either on a sensor based feedback or […]
Electric Wheelchair using BLDC Motor
In this post I have explained how to make a simple electric wheelchair circuit using a standard BLDC motor driver circuit, and a couple of high power BLDC motors. Introduction The introduction of electric wheelchair was like a boon to our many differently-abled friends who now find it much easier to move and travel around, […]
