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 […]

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 […]
How to Interface Servo motors with Arduino
In this post I have explained what servo motor is, how it functions, how to interface with microcontroller and what make this motor special from other motors. Being an electronics enthusiast we would have come across many kinds of motors, here we are going to take a look at special type of motor called servo […]
Understanding Scalar (V/f) Control for Induction Motors
In this article I will try to explain how scalar control algorithm is implemented for controlling induction motor speed with relatively straightforward calculations, and yet achieve a reasonably good linearly variable speed control of the motor. Reports from many top market analysis reveal that induction motors are the most popular when it comes to handling […]
Automatic Torque Optimizer Circuit in Electric Motors
In this article I have explained a circuit design which will help to optimize the torque of an induction motor used in electric vehicles, by analyzing its current consumption. Using a IC 555 Inverter for Toque Control The design is specifically intended for electric vehicles which are designed to work with induction motors, and therefore here […]
How Stepper Motors Work
In this post I have explained about stepper motor. We will be exploring what stepper motor is, its fundamental working mechanism, types of stepper motor, stepping modes, and lastly its advantages and disadvantages. What is stepper motor? Stepper motor is brushless motor; its rotating shaft (rotor) completes one rotation with a determined number of steps. […]
