Abstract (en)
[origin: WO2018065455A1] The invention relates to an optimized segment magnet for a permanent magnet motor. By establishing a magnetization profile within the segment magnet in accordance with a continuous cyclic function, optimized operating characteristics for the electric motor can be achieved with a reduced use of material. The cyclic formation of the magnetization direction in the segment magnet can also be combined with shaping in accordance with a further cyclic function, in order to intensify this effect further.
