Comparison of Vehicle Drives

Selection of Electric Drives to Maximize Range

We analyse for you which per­for­mance class the elec­tric dri­ve of your hybrid vehi­cle must have in order to have the great­est pos­si­ble fuel sav­ings at the low­est cost. For your elec­tric vehi­cle, we will find the best pos­si­ble com­bi­na­tion of elec­tric dri­ves to get a max­i­mum range with the small­est pos­si­ble bat­tery capacity.

Based on your require­ments for the dri­ve sys­tem, we find the opti­mum com­bi­na­tion between gear ratio and the char­ac­ter­is­tic curve of the elec­tric motor. This includes the selec­tion of the right type of elec­tric motor and its torque char­ac­ter­is­tic, as well as the nec­es­sary cool­ing for your dri­ve system.

Accord­ing to your wish­es we devel­op any kind of elec­tric motor for elec­tric and hybrid vehi­cles. You receive a com­plete com­par­i­son of all influ­enc­ing fac­tors, such as the num­ber of pole pairs or the num­ber of slots and lay­ers in the sta­tor. Our main focus is to devel­op the elec­tric motors in such a way that they can be pro­duced in large quan­ti­ties ful­ly auto­mat­i­cal­ly and, above all, cost-effectively.

We get the max­i­mum per­for­mance from your pow­er elec­tron­ics via appro­pri­ate con­trol, so that even short-term peak loads are no longer a prob­lem. We reduce your man­u­fac­tur­ing costs by match­ing the motor design and opti­mized con­trol soft­ware, which makes it pos­si­ble to reduce the size of your DC link capacitor.
