Explanation: Hysteresis loss is directly proportional to the number of magnetic reversals per second or the speed. 5. The usual lamination thickness selected to minimize the eddy current loss in rotor is _____________
A. 0.1 mm to 0.2 mm
B. 0.3 mm to 0.4 mm
C. 0.4 mm to 0.5 mm
D. 0.9 mm to 0.10 mm
Answer:A
Explanation: Hysteresis loss is directly proportional to the number of magnetic reversals per second or the speed. 5. The usual lamination thickness selected to minimize the eddy current loss in rotor is _____________
A. 0.1 mm to 0.2 mm B. 0.3 mm to 0.4 mm C. 0.4 mm to 0.5 mm D. 0.9 mm to 0.10 mm
Explanation: If lamination thickness is made less than 0.4 mm, the reduction in eddy current losses is achieved, but at the cost of additional labor charges in assembling the rotor. 6. In an induction motor, which of the following is correct:
