Patent abstract
A method of making generally symmetrical lamination stacks for electrical machines comprises producing generally symmetrical pole tips from alternating asymmetrical pieces that each have an additional layer in the asymmetrical portion. With the alternating asymmetrical pieces combined, the resulting pole tip is generally symmetrical with a larger possible pole tip width compared with currently-used interleaved stamping techniques.
