Explain Construction of Electric Motor in points. Answer in points will be marked brainliest ​

Answer 1

Answer:

An electric motor is a device which converts electrical energy into mechanical energy.

Electric motors and their functions:

• A power supply – In general, a simple motor has a DC power source. It provides power for the armature of the motor or field coils.

• Field Magnet (can be a permanent magnet or an electromagnet) – The magnetic field by virtue of Fleming’s left-hand law, helps to produce a torque on the rotating armature coil.

• An Armature or rotor – Maintains the position of the armature coil and provides mechanical support.

• Commutator – It is the Armature Coil revolving interface with a stationary circuit.

• Armature Coil – Supporting the engine to run.

• Brushes – It is a system that conducts current between stationary wires and moving parts, mostly rotating shafts.

• Axle

Working principle of electric motors.

• Take two bar magnets, and leave a small space between the poles facing each other. Now, take a small conductive wire length and make a loop
• Keep this connection between the magnets, so that it is still inside the magnet’s area of influence. Now for the final part.

• Attach loop ends to battery terminals.

• As electricity flows through your simple circuit, you will find that your loop “moves.” The magnet’s magnetic field interferes with that generated by the conductor’s electrical current flow.

Because the loop has become a magnet, it will draw one side of it to the magnet’s north pole, and the other to the south pole. That causes the loop to rotate continuously. This is the idea of an electric motor working.
