Fast inspec­tion of hair­pin stators

The hair­pin sta­tor is an essen­tial com­po­nent of a mod­ern elec­tric motor. These hair­pins are often joined by laser weld­ing to form a wind­ing. The qual­i­ty of this join­ing is cru­cial to the reli­a­bil­i­ty of an elec­tri­cal­ly pow­ered vehi­cle. New man­u­fac­tur­ing process­es, new prod­ucts and unclear qual­i­ty require­ments pose major chal­lenges for man­u­fac­tur­ers. To ensure qual­i­ty, inspec­tions using CT can make an impor­tant con­tri­bu­tion. This enables sta­tis­ti­cal mon­i­tor­ing of the pro­duc­tion process, rapid feed­back in the case of sud­den devi­a­tions and sup­port for process adjustments.

The auto­mat­ed eval­u­a­tion process devel­oped by Micro­vista allows eco­nom­i­cal inspec­tion of large quan­ti­ties. Why?

40 times faster eval­u­a­tion than man­u­al inspection

Scans with adapt­ed spa­tial res­o­lu­tion and high­ly par­al­lel auto­mat­ic eval­u­a­tion at rapid speed make it pos­si­ble to inspect up to 40 sta­tors per day.

Inspec­tion of all hair­pins in elec­tric motors

The CT test­ing method devel­oped by Micro­vista makes it eco­nom­i­cal­ly fea­si­ble to exam­ine the qual­i­ty of every hair­pin joint. A wide vari­ety of para­me­ters, such as pore vol­ume or dif­fer­ent cut sur­faces, can be defined as qual­i­ty para­me­ters. Thus, the auto­mat­ic eval­u­a­tion of Micro­vista offers sig­nif­i­cant­ly more infor­ma­tion than can be pro­vid­ed by stan­dard tools. In addi­tion to clas­si­cal ana­lyt­i­cal meth­ods, sub­tasks are also solved using machine learn­ing tools.
