Electric Motors, Inverters and Electric Drives

PMSM FEM

Electric Motors Development

Accord­ing to your wish­es, we devel­op any type of elec­tric motor for elec­tric and hybrid vehi­cles. You will receive from us 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 vol­umes in a ful­ly auto­mat­ed and, above all, cost-effec­tive way.

Our ser­vices:

  • Elec­tro­mag­net­ic design of elec­tric motors
  • Cal­cu­la­tion of char­ac­ter­is­tic curves and maps
  • Elec­tro­mag­net­ic sim­u­la­tion 2D and 3D
  • Ver­i­fi­ca­tion of elec­tric motor design
  • Effi­cien­cy optimization
  • Max­i­miza­tion of con­tin­u­ous power
  • Design of rotor, shaft and bearings
  • Struc­tur­al analy­sis of shaft, bear­ing and housing
  • Ther­mal sim­u­la­tion of the elec­tric motor
  • Design of motor cool­ing and dimensioning
  • Soft­ware opti­miza­tion of dri­ve and control
  • Acoustic opti­miza­tion and NVH analy­sis (noise, vibration)
  • Series design and man­u­fac­tur­ing optimization

Electric Motor Consulting

We help you to find out which type of elec­tric motor is the best for your elec­tric vehi­cle. We pro­vide you with a crys­tal clear com­par­i­son of the influ­enc­ing fac­tors, such as length, diam­e­ter and num­ber of mag­nets. Since we already know the biggest prob­lems of elec­tric motors, we can help you quick­ly with “out-of-the-box” solu­tions with­in two weeks.

Our ser­vices:

  • Elec­tric motor selec­tion and comparison
  • Cre­ate, ana­lyze and derive requirements
  • Fea­si­bil­i­ty stud­ies & con­cept comparisons
  • Cost opti­miza­tion of rotor and stator
  • Indus­tri­al­iza­tion and man­u­fac­tur­ing strategy
  • Patent research of new elec­tric motor types
  • Prob­lem analy­sis of elec­tric motors and solutions

Inverter Elektromotor

Inverter Consulting

We do not devel­op hard­ware for invert­ers, but we sup­port you in the selec­tion and opti­miza­tion of suit­able pow­er elec­tron­ics or an invert­er. For this we cre­ate require­ments, as well as a hard­ware and soft­ware archi­tec­ture for the invert­er, which we derive from the require­ments of your elec­tric motor. In order for your elec­tric motor to reach its full per­for­mance poten­tial, we devel­op soft­ware func­tions to max­i­mize efficiency.

Our ser­vices:

  • Selec­tion and com­par­i­son of inverters
  • Cre­ate and derive requirements
  • Cre­ate a hard­ware and soft­ware architecture
  • Soft­ware func­tions for con­trol­ling elec­tric motors
  • Func­tions to process cur­rent and posi­tion sensors
  • Ther­mal sim­u­la­tion of MOS­FETs and IGBTs
  • Design and sim­u­la­tion of DC link capacitors

Electric Drive Development

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

Our ser­vices:

  • Selec­tion of elec­tric motor, invert­er and gearbox
  • Opti­miza­tion of elec­tric motor and gear­box ratio
  • Cost opti­miza­tion and industrialization
  • Require­ments analy­sis of motor, invert­er and gearbox
  • Sys­tem archi­tec­ture of elec­tric drives
  • Vibra­tion com­pen­sa­tion of elec­tric drives
  • Risk analy­sis of axis drives
  • Con­cept com­par­i­son of elec­tric drives
  • Patent research of nov­el axle drives

Achsantrieb

Electric Vehicle Development

For your elec­tric vehi­cle, we find the best pos­si­ble com­bi­na­tion of elec­tric dri­ves to achieve max­i­mum range with the small­est pos­si­ble bat­tery capac­i­ty. We ana­lyze for you which pow­er class the elec­tric dri­ve of your hybrid vehi­cle must have in order to have the high­est pos­si­ble fuel sav­ings at the low­est cost.

Our ser­vices:

  • Selec­tion of the dri­ve architecture
  • Dri­ve cycle sim­u­la­tion of WLTP and NEDC
  • Cal­cu­la­tion of the char­ac­ter­is­tic curves of the elec­tric drive
  • Selec­tion of the right elec­tric drive
  • Max­i­miz­ing the range of the elec­tric vehicle
  • Increas­ing peak and con­tin­u­ous power
  • Require­ments analy­sis for the elec­tric drive
  • Link­ing the vehi­cle require­ments to the drive
  • Dri­ve con­cept com­par­isons and fea­si­bil­i­ty studies
  • Cost opti­miza­tion between bat­tery and elec­tric drive
  • Dri­ve selec­tion, com­par­i­son and benchmarking
