Extracted text: 2. Why it is necessary to start an I.M. at reduced voltage? 3. The fuse in one of the supply phases of a running 3-phase I.M. blows off. Will the motor continue to run at ( i) original speed (ii) reduced speed (iii) come to stand still? 4. How can the direction of rotation in I.M. be reversed? 5. Why the power factor of induction motor low at no-load and increase as load increasing?
