Magnetic fields force moving electrically charged particles in a circular or helical path. This force—exerted on electric currents in wires in a magnetic field—underlies the operation of electric motors.
What is the fundamental operating principle of electric motors?
The basic principle for all working motors is the magnetic attraction and repulsion. Since a magnet no longer moves once it has attracted, a motor needs some way to manipulate the magnetic fields so that the magnets attract and repel continuously. One way to do this is to have the current changing directions.
What is the basis for the operation of an electric motor?
How do motors work? Electric motors work by converting electrical energy to mechanical energy in order to create motion. Force is generated within the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current.
What is the process of an electric motors motion?
Electric motors turn electricity into motion by exploiting electromagnetic induction. A simple direct current (DC) motor is illustrated below. The motor features a permanent horseshoe magnet (called the stator because it’s fixed in place) and an turning coil of wire called an armature (or rotor, because it rotates).
What is the process in troubleshooting an electric motor?

What are the two main components of an electric motor?
The two main components of this kind of motor are the stator (stationary element) and the rotor (rotating element). The stator is a fixed part of the stationary motor.
What is electric motor class 10th?
Electric motor is a device that converts electrical energy to mechanical energy. Parts of a Electric Motor. Insulated Copper wire: A rectangular coil of wire ABCD. Magnet Poles: A magnet as placed above ie North Pole and South Pole.
What are the three basic parts of an electric motor?
Electric motor designs can vary quite a lot, though in general they have three main parts: a rotor, a stator and a commutator. These three parts use the attractive and repulsive forces of electromagnetism, causing the motor to spin continually as long as it receives a steady flow of electric current.
What are the types of motors?
Types of Electric Motors
- AC Brushless Motors. AC brushless motors are some of the most popular in motion control. …
- DC Brushed Motors. In a DC brushed motor, brush orientation on the stator determines current flow. …

- Linear Motors. …
- Servo Motors. …
- Stepper Motors.
What is the principle of motor?
The principle of an electric motor is based on the current carrying conductor which produces magnetic field around it. A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.
