ABSTRACT:
A method of making composite electric machine components. Magnetic segments and non-magnetic segments are separately formed to green strength, and then arranged adjacent to each other in a desired magnetic pattern. A small amount of powder material is added in-between the segments, and the whole assembly is then sintered to form a sinterbonded composite component of high structural integrity.
