E-mobility. A technological leap in the production of electric motors for rotor and stator tools.

Pressing of rotor and stator sheets.

Tool optimization options for rotors and stators for longer life and more powerful end products

An electric motor consists, among other things, of a rotor and a stator, which are made of many individual sheets. Thanks to optimized production processes, it is possible to reduce the power consumption of the motors, and thus the current consumption of the drive motors, compared to normal production by up to 30%.

Optimization options include, among other things, reducing the thickness of the sheets, which leads to narrower shear gaps (only a few µm in size). This requires especially stiffer guidance in the highest precision tools. With reduced sheet thickness, a significantly higher number of pieces (higher tool life requirements) and stroke frequency are required to maintain or even reduce production time.

Tool maintenance is gaining importance. Maintaining the sharpness of the cut of the active elements is necessary to prevent the formation of burrs on the pressed part, and therefore the most massive losses of performance on the final product. More frequent maintenance requires optimal guide elements that do not show any loss of accuracy even during repeated assembly and disassembly.

Agathon offers various solutions for new requirements in the area of ​​rotor and stator tools. Guide elements are available from stock or are manufactured to order. Depending on the guide systems, a frequency of up to 2500 strokes/min can be achieved. It is possible to use roller guides for maximum stiffness and precision of the guide. It is thus possible to realize the narrowest shear gaps with dimensions of only a few µm. Agathon guide elements enable the easiest assembly and disassembly for maintenance without loss of precision and play a decisive role in extending maintenance intervals, which means a significant reduction in costs. With the standard steel 100Cr6 (1.3505) chosen for the rolling bearings, the optimal prerequisites for further extending the service life of the guide elements and reducing production costs are met.
