A stator core for a large turbine generator may contain over 200 000 punchings. These punchings are clamped axially to cause them to act as a solid mechanical body. Two basic methods are used to achieve the axial clamping force. In one through bolts are passed through holes punched in the core yoke.
Rotor Winding. In a motor the rotating part is known as the rotor. The rotor includes the rotor winding as well as rotor core. The rotor winding is energized by the DC supply. The rotor can be classified into two types namely the phase wound and the squirrel cage. The squirrel cage rotor’s core is made up of cylindrical iron core which has a

The stator is built up of high grade alloy steel laminations to reduce eddy current losses. It has three main parts namely the outer frame the stator core and a stator winding. Outer frame. It is the outer body of the motor. Its main function is to support the stator core and to protect the inner parts of the machine.

I decided to add slot insulation just in case of a wire short to stator edge or something else. So I used Ganex DMD 2 3 2 0.18mm which is half the price of the Nomex stuff yet still good till 150 degrees C. DMD stands for Dacron Mylar Dacron for what its worth. I also used a D profile fibreglass rod called a topstick to keep the wires in the stator slots.
