Claim 12:
13. A method of modifying the torque capacity of an axial flux modular motor of an ESP system having two or more modules disposed within a common motor housing, the method comprising:
first, removing an end subassembly from the motor housing to access a first module of the two or more modules of the axial flux modular motor;
second, removing the first module of the axial flux modular motor from the motor housing, wherein the first module includes at least one rotor having a rotary shaft and one stator, wherein the rotary shaft of a first module is decoupled from a rotary shaft of the axial flux modular motor, and wherein a power transfer terminal of the first module is disconnected from a power transfer terminal of the axial flux modular motor; and
third, installing a second module of an axial flux modular motor in the motor housing, wherein the second module includes at least one rotor having a rotary shaft and one stator, wherein the rotary shaft of a second module is coupled to the rotary shaft of the axial flux modular motor, wherein a power transfer terminal of the second module is connected to the power transfer terminal of the axial flux modular motor;
wherein the first module, the second module or both comprise at least two rotors and at least one stator or at least two stators and at least one rotor, with an axial gap therebetween;
whereby a torque capacity of the axial flux modular motor has changed from an original capacity to a modified capacity; and
wherein the axial flux motor remains connected to a pump, a seal section, or a combination thereof during the modifying of the torque capacity of an axial flux modular motor.
