ABSTRACT:
Magnetic motor component sleeves (209) for motor components with the sleeves (209) having various helpful magnetic characteristics, such as high magnetic permeability; magnetic saturation; residual (or remanent) magnetization; anisotropic magnetic properties. Method for making a magnetic linear motor shaft (202), including thermal treatment to temporarily change the dimensions of various shaft components to allow tight assembly.
