1. Primary Functions
Support the Rotor: Bearings hold the weight of the rotor shaft, ensuring it stays centered.
Reduce Friction: By utilizing rolling elements or lubricants, they minimize heat generation and energy loss.
Manage Loads: They handle radial loads (perpendicular to the shaft) and axial loads (parallel to the shaft), preventing unwanted shaft movement.
Maintain Alignment: Proper alignment is crucial for efficient electromagnetic operation and to avoid damage to stator windings.
