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.
Claims4
A building set for building a plurality of models of different types of electrical machines each comprising a rotor and a stator and having a plurality of magnetic elements mounted on the stator in a predetermined arrangement depending on the particular type of electrical machine to be constructed by the assembly of the components of the building set, said building set comprising a base plate provided with coupling means for detachably mounting a pair of stator elements thereon, said stator elements having bearing apertures for mounting a rotor shaft therebetween and a plurality of coupling means for detachably mounting a plurality of magnetic elements in a predetermined arrangement on the stator elements, said magnetic elements having complementary coupling means, said building set further comprising a substantially disc-shaped rotor element adapted to be mounted on the rotor shaft intermediate the stator elements and said rotor element comprising a plurality of coupling means for detachably mounting a plurality of magnetic elements having complementary coupling means in selected positions depending on the arrangement of the magnetic elements mounted on the stator elements as determined by the type of machine to be built by the components of the building set wherein the coupling means of the rotor element is a plurality of coupling holes, and the coupling means of the magnetic elements is a pair of complementary coupling prongs.
