Often one gets to hear the word “Servo Motor” in electronics. You might have used it many times in your projects as well. But what is inside it and how does it work? Let’s find out. Servo motor is basically...
In this small project, the presenter will show you how to build a custom ESC/Servo Tester. He will also show you how to setup the timer of the ATmega328P in order to create the required control signal. In the...
Various automation processes in the industry need control of AC induction motors using AC drives. Presented here is a robust system for switching on/off, varying the speed and direction of rotation of an industrial 3 Phase Induction Motor using...
In this video, the presenter will conduct a small experiment in order to show you whether the DC, BLDC or Stepper Motor is best suited as a generator. Along the way, we will learn the theory of those motors. Courtesy: GreatScott!
Here is a simple water pump controller circuit for controlling the water level in an overhead tank. The main components of this pump controller are a step-down transformer, a 24V AC double-changeover relay, two floats and two micro switches. Water...
Presented here is a project for controlling stepper motor using rotary encoder. It consists of a Raspberry Pi (Raspi) board, 5-pin rotary encoder, 5V stepper motor and an L293D motor driver. Author’s prototype is shown in Fig. 1. A rotary...
In this video, the presenter will give you a short animated tutorial on how three-coil DC motor works. This includes its working, construction, parts explanation, etc. Courtesy: Learn Engineering
How does an Induction motor start? In order to start a high power rating induction motor, a starting technique called star-delta is used. In this video, the presenter will help you understand why a star-delta starter is needed, and how...
A short video demonstrating how to use a small battery operated (DC) motor as a generator. Also includes a method for determining the efficiency of a generator. Courtesy: ScienceOnline
Ever wondered how your mobile vibrates? Let us see. There is a small motor in your phone, which is responsible for shaking it every time you receive a notification. I observed this phenomenon in a Motorola phone by removing...
