Elektromašīnas montāžu veic pēc visu komplektācijas mezglu sagatavošanas. Kā piemērs tālāk ir aprakstīts 1. attēla redzamās elektromašīnas montāžas paņēmiens (elektromašīnas demontāžu veic pretējā kartībā): vispirms uz pamatnes 2 uzstāda statoru 4 uz balsteņiem 5, centrējot tos attiecība pret centrālo asi 12; pēc tam pamatnei 2 piestiprina slīdošos atbalstus 6, kas fiksē atstarpes starp statora 4 un rotora 7 aktīvajām pusēm, un diskam 8 piestiprina rotoru 7, centrējot to attiecība pret centrālo asi, kā arī piestiprina kontaktplaknes 9 un 10 un cilindrisko kontaktvirsmu 11; pamatni 2 ar uz tās uzstādītiem statoriem 4 un slīdošiem atbalstiem 6 savieno ar sakompektēto disku 8 un veic atstarpes starp statora 4 un rotora 7 aktīvajām virsmām regulēšanu; elementiem 3 piestiprina slīdošos atbalstus 14, elementus 3 uzstāda uz pamatnes 2, veic rotora 7 stāvokļa regulēšanu attiecībā pret kopējo centrālo asi 12 un elementus 3 piestiprina pamatnei 2, kā arī uzstāda aizsargnorobežojumu 15.The assembly of the electric machine is carried out after preparation of all assembling units.

Citu elektromašīnas realizācijas variantu montāžu veic analoģiski. Elektromašīnas, kas satur magnētus atstarpju starp statoru un rotoru aktīvajām pusēm fiksācijai, montāžu veic tā, lai magnētu, kas ir piestiprināti diskam ar rotoriem, pamatnēm un minētajiem elementiem, magnētiskie poli būtu vērsti viens pret otru un lai atstarpe starp poliem būtu tāda pati, kā atstarpe starp statoru un rotoru aktīvajām pusēm.Other versions of the electric machine are assembled analogously. The assembly of an electric machine containing magnets for fixing the active sides of the stator and the rotors is done so that the magnetic poles of the magnets attached to the disk with the rotors, bases and the said elements face each other and that the distance between the poles is the same clearance between stator and rotor active sides.

Iepriekš uzdotas atstarpes starp rotoru un statoru aktīvajām pusēm uzstādīšana un to orientēšana attiecībā pret kopējo centrālo asi, izmantojot slīdošos un magnētiskos balsteņus, ļauj elektromašīnai izturēt ass slodzi, kā arī ļauj izgatavot elektromašīnas lielgabarītu piedziņām, pie kam vairāku elektromašīnu savienojuma vietu apvienošana ļauj palielināt vienas piedziņas kopējo jaudu.Installing a predetermined gap between the rotor and stator active sides and orienting them relative to the common central axis, using sliding and magnetic brackets, allows the electric machine to withstand the axle load, as well as making the electric machine for bulky drives, combining multiple electric machine junctions total power.
