Servo Motor in Hindi एक स्पेशल मशीन होती है जो कि सर्वो मैकेनिज़्म की हेल्प से ऑपरेट होती है। सर्वो मोटर का उपयोग किसी स्पेसिफिक टास्क को प्रिसाइज तरीके से पूरा करने के लिए किया जाता है। इसका वर्किंग प्रिंसिपल इंडक्शन मोटर के जैसा होता है लेकिन इसका construction और operation उससे अलग होता है। … Read more
Equivalent Circuit of Synchronous Motor क्या होता है इस topic में हम Phasor Diagram of Synchronous Motor in Hindi और उसके equivalent circuit को समझते हैं। Equivalent circuit का उपयोग किसी भी electrical machine के electrical characteristics को represent करने के लिए किया जाता है। Synchronous motor के equivalent circuit में V terminal voltage को … Read more
Synchronous Motor Excitation: एक विस्तृत समझ Synchronous Motor Excitation in Hindi को गहराई से समझने से पहले, यह याद रखना अत्यंत आवश्यक है कि किसी भी electromagnetic device को आवश्यक working flux उत्पन्न करने के लिए AC source से magnetizing current प्राप्त करना पड़ता है। यह Magnetizing Current, सप्लाई वोल्टेज (V) से लगभग 90° पीछे (lag) रहता है। दूसरे शब्दों में कहें तो, इस … Read more
Understanding the brake test of dc motor: Imagine trying to find out how well a DC motor is working—how much of the electrical power it uses turns into useful mechanical work. One easy and direct way to check this in a lab is by do something called a Brake Test. Let’s break it down in … Read more
Three-Point Starter A three-point starter is commonly used to safely start DC shunt motors. Just like the two-point starter, it controls the high inrush of current when the motor is switched on. But this one comes with an added feature—overload and no-voltage protection, making it more reliable. What is a Three-Point Starter? The name “three-point” … Read more
DC Motor Starter: DC motors, especially those below 1 HP (0.746 kW), can often be directly connected to a power supply. This is possible because smaller motors have a relatively high armature resistance (Ra), which naturally limits the starting current. Some examples include: However, this direct online starting method cannot be used with larger motors … Read more
What Is Speed Regulation? Think about riding a bicycle. When you’re going downhill with no backpack, it’s super fast and smooth. But going uphill with a heavy bag? How to calculate the speed regulation of DC motors? DC motors act the same way. When there’s no load, they run fast. When there’s a heavy load, … Read more
Complete Guide to Swinburne Test DC Machine The Swinburne Test is a simple and useful method to check the performance of DC motors. It helps us know how much energy the motor uses and how efficient it is. This guide will explain everything in a very simple way. Let’s learn step by step! 1. Step-by-Step … Read more
How to Speed Control of DC Shunt Motors: While controlling the speed of a DC shunt motor may seem like a daunting task, with a little bit of guidance, it can be very simple. This tutorial will break this down step by step with simple language and relevant illustrations. 🔌 A DC Shunt Motor: A … Read more
What is DC Motor Speed Control? Every electric motor has a fixed speed written on its nameplate. This is called the rated speed. It tells us how fast the motor is supposed to run when it’s working normally. But in real life, things keep changing. When the load on the motor changes — like if … Read more
