1. An ESP system, comprising:
a submersible axial flux motor assembly compromising two or more detachable motor modules of an axial flux motor coupled together, wherein the two or more detachable motor modules are disposed within a separate common motor housing, wherein the common motor housing is a unitary housing configured for the two or more motor modules to be jointly disposed therein and each of the two or more motor modules are separately removable from within the common motor housing, wherein each motor module includes at least one stator and one rotor having a rotary shaft, wherein at least one of the two or more motor modules comprises at least three rotors and at least two stators with an axial gap therebetween, and wherein the rotary shafts of the two or more motor modules are rotationally coupled together;
a seal section sealingly engaged with the axial flux motor assembly and coupled to the rotary shaft of a terminal module of the axial flux motor assembly; and
a pump coupled to the seal section and rotationally connected to the rotary shaft.
