Induction Motor Even if the machine is lossless we cannot ignore the electrical portion of airgap power which When we subtract friction and windage losses from the developed power then we obtain the shaft power. In Induction machine we do not merge core loss and mechanical loss as rotational loss because there location inside the […]


Conducting Material (Cu vs Al) •Electrically Conducting Material :- This materials carry current in an electrical machine. •Highly Conducting Material :- Copper, Aluminum, Gold, Silver. •Highly resistive material:- Alloys (heating elements)             Now,    R=Ro(1+αΔT) Where α= temperature coefficient of resistance ΔT= Change in temperature of per degree Celsius ΔT= Change in temperature of per degree […]
