The principle of a motor is the conversion of electrical energy into mechanical energy.

• Motors work based on the principle of electromagnetic induction.

• When an electric current flows through a wire in the presence of a magnetic field, a force is exerted on the wire, causing it to move.

• This movement is used to generate mechanical energy, which can be used to perform work.

• Motors can be found in various applications such a...read more

There are two main types of compressors: positive displacement and dynamic.

• Positive displacement compressors include reciprocating, rotary screw, and rotary vane compressors.

• Dynamic compressors include centrifugal and axial compressors.

• Reciprocating compressors use pistons to compress air, while rotary compressors use rotating elements.

• Centrifugal compressors use a high-speed impeller to accelerate air and convert kine...read more
