Abstract: A motor in different embodiments with a rotatable torque created by permanent magnets having stator and rotor assemblies, each comprising peripherally disposed permanent magnets spaced apart with soft iron insertions filled therebetween, both shaped and magnetized so that producing predominantly mono-polar field in an airgap between each pair of interfacing rotor and stator assemblies, the airgap widening from the first to last magnet of stator; which magnets specifically superimposed forming a connecting magnet; the connecting magnets of different stator assemblies relatively located at a predetermined angle, and the numbers of assemblies magnets having no common multiple. Said permanent magnets are shaped as annular segments of one-thread radial or three-dimensional spirals, said insertions are shaped as three-planeside prisms.
