What is the work of the starter with respect to the mechanical stress?(a) to allow large mechanical stress(b) to restrict large mechanical stress(c) to allow small mechanical stress(d) to restrict small mechanical stressThis question was posed to me in class test.Asked question is from Motor Starters, Calculation of Resistance Steps & Design of Field Regulators topic in portion Design of Small Electrical Machines, Starters and Field Regulators of Design of Electrical Machines

Answer»

Correct option is (b) to restrict large MECHANICAL stress

Easiest explanation: The main function of the starter is to PREVENT the EXCESSIVE current at the STARTING. The other work of the starter is to restrict the large mechanical stress from acting on the MACHINES.
