The invention provides a fault sensing method and system of a micro motor, and relates to the technical field of signal processing, based on a fault sensing module, sensing signals of the micro motor are acquired, and sensing signals of an integrated object are acquired through a data acquisition card; the method comprises the following steps: establishing a signal separator, carrying out signal separation on a sensing signal of a micro motor and a sensing signal of an integrated object, outputting a separated sensing signal, carrying out fault sensing, and outputting a fault sensing result. The technical problems that due to the fact that external interference factors are not considered, the purity of collected signals is insufficient, the integrating degree with the real-time state of the motor is insufficient, and a fault sensing result deviates are solved, sensing signals of the micro motor are collected, interference is carried on the basis of signals of an integrated object, and signal separation and fa
