Abstract
A two pole permanent magnet rotor which utilizes a single cylindrical two pole permanent magnet mounted between two end pieces and surrounded by a retaining hoop. The cylindrical two pole permanent magnet, which is made of high energy product material, is 'straight through' diametrically magnetized to provide a sinusoidal air gap flux distribution which eliminates losses due to harmonics. The cylindrical two pole permanent magnet may be made of a plurality of smaller magnet blocks which are stacked and machined to form cylindrical configuration.
