ABSTRACT:
An electrical machines constructional set comprises a base plate for mounting a pair of stator elements and including bearing apertures for a rotor shaft and a plurality of coupling holes for magnets or electro-magnets provided with complementary coupling prongs. A disk-shaped rotor element also has coupling holes, the number and arrangement of the coupling holes in the rotor element being the same as in the stator element so that parts are interchangeable to construct an electrical motor. A pair of circular disk elements made of soft iron having holes complementary to those of the stator and rotor elements are mounted on each end of the shaft to concentrate the magnetic flux provided by the magnetic elements.
