End caps and brackets are structural components that secure and align stator/rotor assemblies in electric motors and generators.
End caps, also known as end brackets or bearing housings, are precision-machined components that enclose the stator and rotor assembly at both ends of an electric motor or generator. They provide mounting points for bearings, maintain precise rotor alignment, ensure proper air gap between stator and rotor, and often serve as mounting interfaces for the entire motor assembly. Brackets refer to supporting structures that may be integrated with or separate from end caps, providing additional rigidity and attachment points.

End caps specifically refer to the components that enclose the ends of the motor and house the bearings, while brackets are supporting structures that may be part of or attached to end caps to provide mounting points and additional rigidity.
Material affects thermal expansion, vibration damping, corrosion resistance, and weight. Cast iron provides excellent damping but is heavy, aluminum offers good heat dissipation and light weight, while engineered plastics reduce weight and cost for certain applications.
Properly manufactured end caps maintain precise rotor-stator alignment, minimizing air gap variations that cause magnetic losses. They also ensure bearing alignment reduces mechanical losses from friction and vibration.
