The hollow shaft can resist more torsion load with the same resisting area (same weight) as compared to the solid shaft. Therefore the shaft of the induction motor must be of the hollow type.
The advantage of hollow shafts:
1.High tolerance to the rotational imbalance due to low weight.
2.Low rotational inertia
3.Lightweight comparable to the solid shaft of the same diameter
4.Due to low specific mass hollow shafts can tolerant to high-temperature
5.Cheaper in cost
