Abstract: A stator for electric motors, includes a core having an upper and a lower portion and having teeth forming slots therebetween, first and second coil locking layers fixedly mounted on respective upper and lower portions of the core, and a plurality of preformed coil assemblies mounted on respective teeth of the core. Each coil wound carrier includes a winding section having an elongated opening configured to be adjusted around the corresponding tooth, and a first and a second winding carrier connected to opposite ends of the winding section. The first and second winding carriers include a projecting mating part, and the first and second coil locking rings include mating openings of complementary shape inside which are fitted the projecting mating part of respective first and second winding carriers of one of the preformed coil assemblies.
