定义
A stator frame is a critical structural component in electrical generators that provides mechanical support, alignment, and protection for the stator core and windings. It ensures proper air gap maintenance between stator and rotor, facilitates cooling through ventilation channels, and withstands electromagnetic forces, vibrations, and thermal expansion during operation. The frame's design directly impacts generator efficiency, reliability, and heat dissipation.
工作原理
The stator frame functions as a rigid mechanical structure that maintains precise alignment of stator components while dissipating heat generated by electromagnetic losses. It provides mounting points for the stator core laminations, supports winding assemblies, and channels cooling air or liquid through designed passages. During operation, it resists torsional and radial forces from magnetic fields, prevents deformation under thermal stress, and minimizes vibration transmission to surrounding structures.
材料
Low-carbon steel plates (ASTM A36/A572)cast iron (GGG40/GGG50)or fabricated steel with corrosion-resistant coatings. High-power generators may use non-magnetic stainless steel (304/316) to reduce eddy current losses.
