In induction machine when the load increase the current
will increase .why?
what is the relation ship between the sleep and current
drown by stater?

Answer Posted / anonymus

Expression for current in Induction motor is given by;
I=Vs/√((r1+r2/s)^2+(x1+x2)^2 )
Where: I= stator current
Vs= Stator Voltage
r1,r2,x1 and x2 are stator resistance, rotor resistance,stator impedance and rotor impedance
s= slip
As load increases rotor speed decreases. Since,[s=(Ns-Nr)/Ns] as a result slip(s) increases hence the term (r2/s) decreases and the net impedance decreases and the current I(inversely proportional to impedance as also can be seen from equation) increases.

Given a collection of points P in the plane, a 1-set is a point in P that can be separated from the rest by a line; i.e. the point lies on one side of the line while the others lie on the other side. The number of 1-sets of P is denoted by n1(P). The maximum value of n1(P) over all configurations P of 19 points in the plane is 18
