Stator

The advantages of the continuous hairpin lie in the economic feasibility of high numbers of slots with large inside diameters. With this technology, the prefabricated wire mat is inserted into the stator, making small wire cross-sections easily manageable and eliminating the need for complex circuitry. GROB uses flat winding for continuous hairpin assembly. An innovative bending concept enables very high flexibility and a wide range of variants. By using preformed, open coil segments made of conductors with a rectangular cross-section (so-called hairpins) and the high degree of automation, this technology allows high-quality stators with the highest filling ratios to be manufactured. The advantage of the coil-inserting technology lies in a proven process. It is used in electric motors for all size and performance classes, from consumer goods to the automotive industry. GROB offers two methods for manufacturing stators using the insertion technique: Flyer winding Twist-free Needle winding technology is a complex process for applying round wire for e.g. externally excited rotors. The advantages of this process are, on the one hand, the consistent performance of the rotor over its entire service life and, on the other hand, the possibility of control via copper packets.
