A DC motor is an electric motor that converts direct current electrical energy into mechanical energy.

• DC motors are commonly used in household appliances, electric vehicles, and industrial machinery.

• They consist of a rotor, a stator, and a commutator.

• The direction of rotation can be reversed by reversing the polarity of the input voltage.

• DC motors are more efficient than AC motors at low speeds and can provide high tor...read more

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

• Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.

• They consist of two coils of wire, called the primary and secondary coils, wrapped around a magnetic core.

• When an AC current flows through the primary coil, it creates a magnetic field th...read more

DC machine is an electrical machine that converts DC electrical power into mechanical power.

• DC machine stands for Direct Current machine

• It consists of a stator and a rotor

• The stator produces a magnetic field and the rotor rotates due to the interaction of the magnetic fields
