Literature Review: Gearless Motor Failures – A Mill Designer’s
The stator is fixed on both sides of the frame or at the bottom. There is no sliding at the foundation supports to prevent the generation of large thermal expansion loads in the frame and the foundation during operation. These thermal loads are only limited by the cooling system of the stator. A mill is much simpler.

Induction Motor: Construction, Working principle & Advantages
Stator core. A stator consists of a stack of laminations of silicon steel in the form of a ring. It fits inside the stator frame and contains slots on its inner periphery. These slots carry the three-phase winding, separated by 120 degrees in space. Right here, the figure shows the distribution of three-phase winding in a stator.

Grinding Mill Foundations
The El Teniente SAG mill foundations had to be stiffened as did the stator frame to ensure there would be no vibration because the soil properties were very poor. Foundations cannot be built on piles. Wrong again. There are successful examples of piled mill foundations. The mill vendor should be responsible for the system analysis. Wrong.
