Claim 0:
1. A counter-rotating motor, comprising:
a stator, comprising an outer winding and an inner winding, wherein a phase sequence of the outer winding is reverse to a phase sequence of the inner winding;
an inverter, connected in parallel with the outer winding and the inner winding and configured to supply excitation current to the outer winding and the inner winding synchronously;
an inner rotor, arranged at an inner side of the inner winding and configured to rotate in a first direction by an action of the inner winding; and
an outer rotor, arranged at an outer side of the outer winding and configured to rotate in a second direction opposite to the first direction by an action of the outer winding;
wherein the inverter is configured to perform a closed-loop vector control of the second squirrel cage rotor, permanent magnet rotor, or reluctance rotor, the first squirrel cage rotor is configured to automatically operate in a V/F open-loop control mode.
