Magnetic Rotors - Example of design
An example of the basic components of a rotor can be found below:
Shaft in stainless steel – available with or without a through-going hole.
Sliding bearing in tungsten carbide – sprayed on as a coating. The hard alloy on the bearing ensures high wear resistance and a very long service life for the shaft.
Core in soft magnetic material, ordinary solid iron or laminated iron.
Magnetic rings or segments in several different types of material – isotropic or anisotropic.
- Optional rotor housing in stainless steel for hermetic enclosure of magnets and soft magnetic materials – used, for example, for wet runners.
