An electric motor housing including a metal internal hub and composite material reduces weight, reduces motor vibration transmission, increases mechanical damping, improves corrosion resistance and improves electrical performance.

Composite motor end housing with a metallic sleeve bearing support

An electric motor housing is made by press-forming a composite material on a metal cylinder and machining passages in the press-formed material. This reduces weight, reduces motor vibration transmission, increases mechanical damping, improves corrosion resistance and improves electrical performance.

Method for making a composite electric motor housing

A composite electric motor shaft including axially distributed metallic and nonmetallic sections joined together exhibit increased mechanical damping, increased rotor critical speed, improved corrosion resistance and improved motor performance.
