Faraday’s Law of Induction

A power drill converts electrical energy to mechanical energy when plugged in and used. Music converts sound energy to mechanical energy in your eardrum.

Energy can be converted from one form to another. Examples: Gasoline (chemical) is put into our cars, and with the help of electrical energy from a battery, provides mechanical (kinetic) energy. Similarly, purchased electricity goes into an electric bulb and is converted to visible light and heat energy.

The Difference Between Electric Motor and Electric Generator in Tabular Form

You can use just about any motor to generate electric current, if it is wired correctly and you follow specific rules for its use. Modern AC induction motors are quite simple to wire as alternating current generators, and most will begin generating electricity the first time you use them.

The basic principle of all electric generators is electromagnetism. The magnetic field should be moved to generate electricity.

Noun. 1. basic principle – principles from which other truths can be derived; “first you must learn the fundamentals”; “let’s get down to basics” fundamental principle, fundamentals, basics, bedrock. principle – a basic truth or law or assumption; “the principles of democracy”

Answer: These two forces – electricity and magnetism – work together to spin the motor.

Every electric motor has two essential parts: one stationary, and one that rotates. The stationary part is the stator. Though configurations vary, the stator is most often a permanent magnet or row of magnets lining the edge of the motor casing, which is usually a round plastic drum.

Electric motor: A motor is a device which converts electrical energy into mechanical energy. Principle of motor : A motor works on the principle that when a rectangular coil is placed in a magnetic field and current is passed through it. Whereas the force on the side CD of the coil is in the upward direction.

Yes, electric motors can get weaker over time. Bearings wear out and electric insulation breaks down and can start developing shorts in the winding’s.

Most efficient vehicle in the world uses brushless motor in drivetrain. One little hydrogen fuel-cell vehicle holds the Guinness world record for the most efficient vehicle … and uses a slotless brushless 60L-H-175-A from Koford Motors to drive its rear power wheel.

The power of the DC motor increases by increasing the torque developed by the shaft/rotor which in turn depends on the current in direct proportion.

How to improve torque and RPM of a DC motor?

1. Case 1: Increase/Decrease strength of permanent magnets. What would happen to torque and RPM?
2. Case 2: Increase/Decrease size of magnet wires. What would happen to torque, power consumption and RPM?
3. Case 3: Increase/Decrease the size of armature.
4. Case 4: Increase/Decrease the number of turns (coil).

One easy way to make the motor run faster is to add another magnet. Hold a magnet over the top of the motor while it is running. As you move the magnet closer to the spinning coil, one of two things will happen. Either the motor will stop, or it will run faster.

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.

On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils.

No matter the type of motor, there are three basic parts: a stator, a commutator, and a rotor. Together they use electromagnetism to cause the motor to spin. As long as the motor receives steady current, the motor works.

An electric rotor. An electric motor is a device used to convert electricity into mechanical energy—opposite to an electric generator. They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field.
