Modular motor assembly

A motor comprising:

• a first modular magnetic assembly comprising a first rotor assembly and a first stator assembly operable to magnetically induce rotation of the first rotor assembly around a motor axis;
• a first stator housing to which the first stator assembly is detachably mounted;
• a second modular magnetic assembly comprising a second rotor assembly and a second stator assembly operable to magnetically induce rotation of the second rotor assembly around the motor axis;
• a second stator housing to which the second stator assembly is detachably mounted;
• one or more intermediate stator housings coupled with and between the first stator housing and the second stator housing to form an annular canister defining an interior space in which the first modular magnetic assembly and the second modular magnetic assembly are disposed;
• and
• a shaft assembly comprising a shaft and a shaft spacer, wherein the first rotor assembly and the second rotor assembly are rotationally coupled to the shaft for rotation with the shaft around the motor axis, and wherein the shaft spacer maintains a separation distance between the first rotor assembly and the second rotor assembly parallel to the motor axis.
