a. How can you increase a starting torque in an induction machine without increasing the losses during normal operations

b. What does the statement design on the \"NEMA B on a motor nameplate mean

Solution

A) we can use direct online starting without having starter and then it gets 5 to 7 times of starting current for a few mins and it causes high starting torque, thus in this we can produce high torque without adding a resistor or a reactor, so no losses occur and constant losses doesn\'t change

B) NEMA means   \"National Electrical Manufacturers Association \"

NEMA B gives the information about how much current in rush is possible according to the standards of  National Electrical Manufacturers Association
