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 […]
Newly Updated Circuit Projects:
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 […]
50V 3-Phase BLDC Motor Driver
This yet another versatile 3-phase driver device in the form of IC L6235 from ST Microelectronics allows you to drive a 50V 3-phase BLDC motor with extreme efficiency.The chip also includes all the required protection features built-in, along with an easy to configure external speed control stage. How the IC L6235 BLDC Driver Works The IC […]
Push Button Fan Regulator Circuit with Display
A very interesting push button operated fan regulator circuit with LED display is explained in the following article, which can be built and installed at home for the suggested purpose. The idea was requested by Mr. Sriram KP. The Design Normally all fan regulators whether it’s a mechanical or electronic employ a rotary kind of […]
Universal ESC Circuit for BLDC and Alternator motors
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 […]
GSM Pump Motor Controller Circuit using Arduino
In this post I will show how to construct a farmer friendly GSM pump motor controller circuit which couldturn on and off the irrigation system remotely from anywhere in the world via cellphone SMS and return you with an acknowledgement message. The idea was requested by Mr. PG Ragavandir. The Design Agriculture is one of […]
