If we classify an induction motor based on the type of rotor used, there are two types of induction motor. The first is a Squirrel cage Induction motor, and the other is a Wound, aka slip ring Induction motor. Both these induction motors have a difference in their construction, starting, cost, and their application. This … Read more
There are four methods to start a squirrel cage induction motor. These are Direct On-Line (DOL), Stator resistance, Auto-transformer, and Star-delta starting, while for a slip-ring induction motor, we prefer rotor resistance starting. Now, you might think that an induction motor is self-starting, then why do we need induction motor starting methods? Right? Don’t worry … Read more
If you are a student, then you might have heard the term Alternator and Generator. Both of them are electrical machines that generate electricity. But, if they both have a similar purpose then, why do we have two different names? What are the differences between Alternator and Generator? If you are looking for similar answers, … Read more
An induction motor is the most commonly used AC motor in homes, offices, and industries. The reasons are its low cost, rugged construction, and sufficiently high efficiency. Based on the AC power supply given to the motor, there are two types of Induction motors, viz, Single-phase and a Three-phase Induction motor. In this article, we … Read more
A Synchronous motor is a type of AC motor that runs at a constant speed. And before discussing the speed control methods of a Synchronous motor, let us see how to find the speed of a synchronous motor. Using this simple formula: , we can calculate the synchronous speed of any synchronous motor.Let’s look at … Read more
There are 5 types of single-phase induction motors on the basis of their starting methods: Resistance start, Capacitor start, Capacitor start capacitor run, Permanent Capacitor, and shaded-pole single-phase induction motor. Each of them is discussed in detail below. A single-phase induction motor creates an alternating magnetic field on giving an AC supply to its windings. … Read more
