Electrical Machines

About the Subject : 

An electrical machine is a device which converts mechanical energy into electrical energy or vice versa. Electrical machines also include transformers, which do not actually make conversion between mechanical and electrical form but they convert AC current from one voltage level to another voltage level.

Topics to be covered in this Seminar :

Magnetic circuits –Flux linkage, Inductance and energy – Statically and Dynamically induced EMF – Torque – Properties of magnetic materials- AC excitation – permanent magnets – Transformer as a magnetically coupled circuit – Construction – principle of operation – equivalent circuit parameters – Sumpner’s test – three phase transformers – connections – Scott Connection – Phasing of transformer – tap changing transformers – tertiary winding  – Electro-mechanical Energy Conversion  – Concepts In Rotating Machines – Construction and components of DC Machine– armature reaction –methods of excitation-commutation and interpoles  – compensating winding – DC Motors–Plugging, dynamic and regenerative braking – Retardation test – Swinburne’s test and Hopkinson’s test  – Permanent magnet dc motors(PMDC) – DC Motor applications.
