What's the function of stator core? How do you decide clamping force? Number of bolts for clamping? What is material for laminated sheets? Why cold rolled sheets?

Question

Accepted Answer

The stator core is a crucial component in an electric motor, providing support and magnetic flux. Clamping force, number of bolts, material, and cold rolled sheets are determined based on design requirements.

The function of the stator core is to support the windings and provide a path for the magnetic flux in an electric motor.
The clamping force for the stator core is determined based on the mechanical load and the desired level of stability.
The number of bolts for clamping the stator core depends on the size and design of the motor, as well as the required clamping force.
Laminated sheets, typically made of silicon steel, are used for the stator core to reduce eddy current losses and improve efficiency.
Cold rolled sheets are preferred for the stator core as they have better magnetic properties and dimensional accuracy compared to hot rolled sheets.
