Since harnessing and creating electricity work the same way, apply electricity to a motor and it spins. Spin a motor and it becomes a generator.Originally posted by Moni

ac is alternating current, dc is direct current (constant). KVA is used because KW doesn't take into account phase for ac.Originally posted by Moni
But what is the basic difference between AC and DC machines?
What is eddy current loss?
why tranformer rating is not KW why it is KVA?
A motor or generator works by converting mechanical energy into electrical energy. This is done through the use of a magnetic field, which is created by the interaction of the motor's or generator's moving parts and an external source of electricity.
The main components of a motor or generator include a stator (stationary part), a rotor (rotating part), and a commutator or slip rings. The stator contains the coils of wire and the rotor has the magnets or electromagnets that create the magnetic field. The commutator or slip rings are used to transfer electricity to and from the rotating part of the motor or generator.
In a motor, the direction of the current is changed by the commutator, which uses brushes to switch the direction of the current as the motor rotates. In a generator, the direction of the current is changed by the movement of the rotor in relation to the stationary stator.
A DC motor runs on direct current, meaning the current flows in one direction, while an AC motor runs on alternating current, meaning the current direction alternates. AC motors are typically used for larger applications, while DC motors are commonly used in smaller devices.
Motors and generators have a wide range of uses, including powering vehicles, appliances, and industrial machinery. They are also used in renewable energy sources, such as wind turbines and hydroelectric power plants. In addition, generators are commonly used as backup power sources in the event of a power outage.
