The invention relates to a method for real-time detection and synchronous coordination control of multiple motor controllers. The method includes: Step A1, detecting connection states of two ports ofmotor controller themselves by the motor controllers in real time; Step A2, if the states change, uploading the motor controller port states to a CAN bus, otherwise returning to Step A1; Step A3, updating received CAN bus data and storing to respective system connection two-dimensional state tables by each motor controller; Step A4, if the number of abnormal nodes in a system N_err>0, giving a system connection abnormality alarm, otherwise returning to Step A3; and Step 5, if the number of abnormal nodes in the system N_err>2, motor controller instructions synchronizing a system fault, all themotor controllers closing output, otherwise returning to Step A4. The method for real-time detection and synchronous coordination control of multiple motor controllers ensures that when the motor controllers in the system los
