Forming Machines from ELMOTEC STATOMAT
Depending on the selected winding method, the individual coil strands of the windings lie unordered and uncompressed in the groove after the insertion process. To allow further phases to be inserted and to increase the mechanical copper filling factor, the windings are widened with the help of a forming machine and pressed into the bottom of the slot (intermediate forming). Once all phases have been inserted and the winding head has been fixed by lacing, the final forming process takes place (final forming). The machine forming thus ensures that the technical properties, especially the filling factor and the final dimensions, are achieved.
Interesting facts about moulding machines from ELMOTEC STATOMAT
At Schaeffler ELMOTEC STATOMAT, we therefore attach particular importance to the often underestimated production step of forming the winding head. Starting with simple pneumatic presses to open the bore after insertion, through intermediate forming presses with expanding laminations expanding lamellas to final forming of the inner and outer diameter as well as the winding head height (3-way system), we offer the right solution for every application. Our patented “No-Gap” tool with closed inner jaws guarantees that there is no wire damage due to jamming of the wire. Collar support fingers on the tool protect the insulating sleeve collars during the moulding process. Schaeffler ELMOTEC STATOMAT moulding machines are available in both hydraulic and electric versions.
Our extensive equipment portfolio, consisting of winding machines, insertion machines, forming machines and lacing machines, completes the process chain for the production of stators.
By using flat wires, the fill factor, and thus the efficiency, of an electric motor can be significantly increased. With the innovative flat wire wave winding, drive concepts can be realised that set benchmarks in the area of power density. An ideal production technology for the challenges of e-mobility.
