How Does an AC Motor Work?

  • AC Motor is known for its electromagnetic induction phenomenon. Now one thing we need to know is that the AC motor contains 2 parts. The first is a stator that contains stationary windings. This helps in generating a rotating magnetic field. The second part is the rotor. Its main function is that it houses the rotating elements. So when current is induced over here, there is a creation of a magnetic field that interacts with the stator.

Difference Between AC and DC Motor

Difference Between AC and DC Motor: The motor is an integral part that plays a crucial role in the world of electrochemical devices. We live in a modern world where at the moment time there are 2 prominent kinds of motors. They have the potential to power our world. These two are AC (alternating current) motors and DC (direct current) motors.

In AC motors, the part that doesn’t move is called the armature, and it’s surrounded by a spinning magnetic field. On the other hand, in DC motors, the armature itself rotates, while the magnetic field around it stays still. AC motors have three input terminals labeled R, Y, and B, whereas DC motors have two input terminals known as positive and negative.

In this article, we will get to know about the difference between AC motors and DC motors along with the definition and applications of AC and DC motors.

What is a DC Motor?

DC motor is a type of electric motor that stands for Direct Current. The role of the DC motor is to convert the electric current into mechanical energy through direct current. The 2 important parts of the DC motor are the stator and armature. This stator consists of permanent magnets....

How Does a DC Motor Work?

The DC Motor obeys the principle of electromagnetic attraction and repulsion. As we discussed above, it contains 2 essential parts. First is the stator and second is the armature. When we supply a direct current to the armature, a magnetic field is generated. This specific interaction between the magnets of the stator and the armature’s magnetic field is the reason behind the rotation of the rotor....

What is the difference between AC and DC Motor?

The rotation of AC motors is such that it generally rotates in a fixed direction which is already decided by the phase of the alternating current, and changing the direction requires additional components. On the other hand, DC motors can easily change their direction of rotation and this is simply done by reversing the polarity of the applied voltage. In reality, the AC motors require less maintenance as the reason behind this is that because they don’t have brushes and commutators that get damaged after certain amount of time. On the other hand the DC Motors require periodic maintenance and that is because in order to replace damaged brushes and commutators. The most general use of AC motors is where a constant speed is required, such as household appliances, fans, etc. On the other hand, DC motors are widely used in applications where the speed must vary such as electric vehicles, robotics, etc....
