文摘

The importance to obtain a lightweight product, to reduce the CO₂emissions and so realize an environmental-friendly product is the most important goal to reach with processing engineering. Regulations and also industries’ marketing policies push the development of new process cycle energetically less expensive and environmentally dutiful. Nowadays a lot of new process has been carried out by those requirements like incremental forming, sheet bulk metal forming and so on.

The author in this work focused their study to the whole production process to obtain a claw-pole rotor, developing numerical models and conducting experimental tests to evaluate material properties, process conditions and observing what occurs with different parameters sets. After collected a good know how about the process, a new type of claw pole rotor was proposed, optimized with energetic criterion. The study gave the possibility to obtain a product with the same forming steps properly set but with a larger geometry not scaled, permitting good savings in term of material used, waste, cycle time and number of processing after the forming in the mechanical press and so to reach the desired electrical properties in output.
