Abstract
Permanent magnets and method of making the same are provided. The magnets include a magnetic layer having an insulation layer disposed thereon. The insulation layer is formed via additive manufacturing techniques such as laser melting such that it has discrete phases including a magnetic phase and an insulating phase.
Claims20
A permanent magnet comprising:
- a substrate;
- a magnetic layer disposed on the substrate;
- and
- a patterned insulation layer disposed on the magnetic layer opposite the substrate including magnetic segments and insulating portions disposed between the magnetic segments, wherein the substrate is a component of a motor.
