Dear all

Suppose i have a slip ring induction motor with stator winding consists of four groups of winding per phase, each two groups are connected in series and with the other two groups are connected in parallel
each group consists of 8 coils
the total no. of coils per phase is 8*4 = 32 coil
the number of slot in the stator is 96 slot

Now my question is, if i remove one coil from any group from each phase so the number of coils per phase will be (3*8)+ (1*7)=31, what will happen to the motor performance i.e. (speed, torque, power, current, efficiency)
and what is the formula for calculating these performance parameters

N.B. : All the motor parameters are defined
waiting for your reply

Thanks for all
