Abstract
Systems and methods for connecting rotors between multiple permanent magnet motors. By coupling the rotors of multiple modules, torque may be transferred while maintaining the angular alignment between the stator and rotor magnetic fields of each individual permanent magnet motor.
Claims27
A system for connecting rotors of multiple permanent magnet motors comprising:
- a first member configured to be coupled with a first rotor associated with a first permanent magnet motor, the first member including a head;
- a second member configured to be coupled with a second rotor associated with a second permanent magnet motor, the second member including a bore, wherein the bore is configured to receive the head;
- wherein:
- the head of the first member is configured to be moved axially along a central axis of the system to be inserted into the bore of the second member;
- and
- the first member and second member are configured to be rotationally locked.
