Claim 8:
9. The driving control method of the stator-based permanent magnet field-enhanced hybrid-excitation motor capable of operating under multiple operating conditions according to claim 8, further comprising: controlling, by one H-bridge alone, an excitation current; and inputting a positive or negative excitation current by controlling four switch transistors to be on, to realize magnetic field enhancement or demagnetization of the motor; inputting, when the motor has an armature winding fault and a demagnetization fault, a single-phase alternating current into the excitation winding through the H-bridge of the excitation winding to form a single-phase alternating current magnetomotive force for working with other phase without a fault, such that the motor operates in a fault-tolerant mode; and when the excitation winding fails and a permanent magnet is demagnetized, the switch transistor is closed, and the power converter of the open winding structure operates in a switched reluctance motor control mode.
