Answer Posted / shankarj23
In motor, there is a factor called slip. Due to which there
is difference between the actual speed (synchronous) and
resultant speed.
In synchronous motor, the slip is 0. that's the reason why
it runs at synchronous speed.
The fixed speed is called SYNCHRONOUS SPEED.
s= (Ns - N)/Ns
Ns=120f/p

True or false question. 1.The fuse provide phase and neutral 2.power loss in electrical circuit can take place in (resistance or inductance or capacitance). 3.two phase system each phase has separated by a phase difference of (90 or 180 or 270 or 45). 4.3 phase balanced star connected load neutral current shall be (line current or phase current or zero or unity)
