Introduction
In simple words, electrical devices that can convert the electrical energy to mechanical energy can be termed as an electric motor. Its working is based on Fleming’s left-hand rule that we will further read in this blog. You must have seen the mixer grinder converting the electrical energy into some form of mechanical energy. The grinder’s motor rotates, rotating the jar cranks at the bottom and hence crushing the ingredients. Similarly, a remote-controlled car also converts electrical energy into mechanical rotating energy with the analogue signal as input.
All types of devices that convert some form of energy like electrical energy to mechanical work are termed as electric motors. Let’s now understand the components of an electric motor.
An electric motor has different parts in it. They are listed below:
These parts are the building components of the electric motor. Let’s understand each part in detail.
There are primarily two types of electric motors— AC motor and DC motor. The basic difference comes in their nature of power supply where the DC motors work on DC power supply, and the AC motors work on AC power supply. There may be a further classification of electric motors based on the components they use, such as brushing or brushless motors and more.
Electric motors are used extensively in many electrical applications and are a primary tool to convert electrical energy to mechanical energy. Some of the appliances in which they are used are:
The major working principle of an electric motor is based on Fleming’s left-hand rule. Let’s look at an example of a DC motor to learn how it works.
Electric motors are an essential component of modern-day instruments and play a vital role in carrying out mechanical work like drilling, rotation and much more. The motors are broadly categorized based on their power supply. They can be AC or DC source motors with different components. You can build a car or even a washing machine by using motors and other necessary parts. Electric motors are widely used and are a boon to the modern world as it helps make things easier.
1. What is the principle of an electric motor?
The basic principle of the motor is that any current going inside a magnetic field will produce a force that will try to move the conductor. It can also be verified by Fleming’s left-hand rule, which tells us the relational direction between the force, field and current.
The armature coil rotates under the direct influence of the torque produced by the moving current in the wire that is inside the magnetic field created by the electromagnets or permanent magnetic materials.
2. What are the different types of electric mot-ors?
The different types of electric motors are:
3. What are the two types of motors?
The two types of electric motors are AC motors and DC motors.
4. Is an electric motor AC or DC?
Both AC and DC are used to power electric motors. The main necessity of any electric motor is a current that is provided by both the AC and DC source.
5. What is an electric motor with a diagram?
Electric motors are very useful devices that convert the electrical energy from any source (AC or DC) to mechanical energy for any productive work. Check the electric motor diagram below:
Aren’t electric motors fascinating devices? On MSVgo, you can learn about how electric motors work with the help of diagrams and animations. It is a vast video library where you can learn about electric motors by understanding the core concepts behind them and also explore interactive learning methods such as MCQ quizzes to solidify those concepts.
