So, we are now on Electrical Technology. According to syllabus of University of Pune, ET (Electrical Technology) is studied in the second year of Mechanical Engineering. By the way, this is totally Electrical Engineering subject. And almost similar subject is there for Electronics and Telecommunication Engineering. The part which is covered in ET is very important when seen from Mechanical Engineering aspect.
D.C.Generator and D.C.Motor:
As name suggests, this part covers D.C.Generator and is pretty easy. D.C.Generator and D.C.Motor are almost same in construction and there workings are just vice verse. D.C. generator takes shaft power in and gives output as electric power and oppositely, D.C. Motor takes electric power in and outputs the brake power on shaft.
Motors, Transformers and Alternators:
There are plenty of motor types and we need them in different applications. So, mere learning the D.C.Motor is not enough. We learn induction motors, special purpose motors like servo motor, stepper motor, synchronous motors etc. Also, we learn transformers and alternators.
Electrical Machine Selection Maintenance and Electrical Power Measurements:
The selection of perticular electrical machine is dependent on type of work to be done. Suppose, when we need to have very high torque from motor the obvious selection could be D.C. series motor. For robot arms, stepper motor or servo motor can be used.
Electrical Heating, Welding and Illumination:
These are most obvious uses on electric energy. Illumination is kind of theory part that covers some basic aspects about lighting or rather types of lighting and efficient lighting. Though easy, Illumination contains huge number of definitions.
So, this is brief of Electrical Technology.
Thanks for Reading.
