how to diffrentiate between ac & dc motors from a distance
Answer Posted / r a m e s h
Differentiation between ac & dc motors
1-Ac motor has induction properties but in Dc motor has no.
2-AC motor has starts with a capacitor to leading starting
torque where DC has shunt the field & split ring
3-the outer shape is plane of dc motor or rectangular in shape
where as AC motor has built in split bar cooling.

Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.
