A system for monitoring a motor includes a movable component having a plurality of permanent magnets. The system also includes a plurality of stators having phase windings and surrounding the movable component. The system also includes a plurality of current sensors each configured to detect a detected current flowing to a corresponding stator of the plurality of stators. The system also includes a monitor configured to receive the detected current, perform a comparison of the detected current from each of the plurality of stators, and to identify a loss of redundancy of the motor based on the comparison.

1. A system for monitoring a motor, comprising: a movable component having a plurality of permanent magnets;a plurality of stators having phase windings and surrounding the movable component;a plurality of current sensors each configured to detect a detected current flowing to a corresponding stator of the plurality of stators;a monitor configured to receive the detected current, perform a comparison of the detected current from each of the plurality of stators, and to identify a loss of redundancy of the motor the based on the comparison; anda plurality of controllers, including a master controller and at least one slave controller, each configured to control the corresponding stator of the plurality of stators. 2. The system of claim 1, wherein each of the plurality of current sensors is located in a corresponding controller of the plurality of controllers. 3. The system of claim 1, wherein the monitor is included in the master controller. 4. The system of claim 1, wherein the monitor is configured to identify the loss of redundancy in response to at least one stator of the plurality of stators having a different detected current than another stator of the plurality of stators. 5. The system of claim 4, wherein the plurality of stators includes at least three stators, and wherein the monitor is further configured to identify a faulty stator in response to identifying that the detected current of at least two of the plurality of stators are within a tolerance current level of each other, and that the detected current of the faulty stator is outside the tolerance current level. 6. The system of claim 5, wherein the monitor is further configured to cause the faulty stator to cease receiving current. 7. The system of claim 1 further comprising an output device configured to output data and wherein the monitor is further configured to control the output device to output a notification indicating the loss of redundancy of the motor. 8. A system for monitoring a motor, comprising: a movable component having a plurality of permanent magnets;a plurality of stators having phase windings and surrounding the movable component;a plurality of current sensors each configured to detect a detected current flowing to a corresponding stator of the plurality of stators; anda plurality of controllers each configured to control the corresponding stator of the plurality of stators and including a master controller configured to receive the detected current, perform a comparison of the detected current from each of the plurality of stators, and identify a loss of redundancy of the motor based on the comparison. 9. The system of claim 8, wherein each of the plurality of current sensors is located in a corresponding controller of the plurality of controllers. 10. The system of claim 8, wherein the master controller is configured to identify the loss of redundancy in response to at least one stator of the plurality of stators having a different detected current than another stator of the plurality of stators. 11. The system of claim 10, wherein the plurality of stators includes at least three stators, and wherein the master controller is further configured to identify a faulty stator in response to identifying that the detected current of at least two of the plurality of stators are within a tolerance current level of each other, and that the detected current of the faulty stator is outside of the tolerance current level. 12. The system of claim 11, wherein the master controller is further configured to cause the faulty stator to cease receiving current. 13. The system of claim 8 further comprising an output device configured to output data including a notification indicating the loss of redundancy of the motor. 14. A method for monitoring a motor, comprising: receiving, by a monitor, a detected current corresponding to each of a plurality of stators;performing a comparison, by the monitor, of the detected current from each of the plurality of stators;identifying, by the monitor, a loss of redundancy of the motor based on the comparison; andoutputting, by an output device, output data including a notification indicating the loss of redundancy of the motor. 15. The method of claim 14, wherein identifying the loss of redundancy of the motor includes identifying the loss of redundancy in response to at least one stator of the plurality of stators having a different detected current than another stator of the plurality of stators. 16. The method of claim 14, further comprising identifying, by the monitor, a faulty stator in response to identifying that the detected current of at least two of the plurality of stators are within a tolerance current level of each other, and that the detected current of the faulty stator is outside of the tolerance current level. 17. The method of claim 16, further comprising preventing, by the monitor, the faulty stator from receiving current.
