The invention discloses an alternating-current motor with an efficient heat dissipation structure, and aims to solve the problem of heat dissipation bottleneck caused by narrow air gaps and thermal boundary layer effects of a traditional alternating-current motor in a compact and closed environment. The invention provides an alternating current motor with an efficient heat dissipation structure. The system comprises an airflow excitation unit and an airflow directional conveying unit which are driven by kinetic energy of a rotor. The airflow excitation unit converts the rotation motion of the rotor into periodic compression of air through a magnetic reciprocating mechanism; the airflow directional conveying unit efficiently conveys compressed air to an air gap area through a multi-stage pressurizing structure, a spiral flow guide structure and a self-adaptive air guide structure. On the premise that the air gap is not increased and the system does not depend on external forced air cooling, active damage and enhanced heat exchange of a heat boundary layer in the air gap are achieved, the heat dissipation efficiency and the operation reliability of the motor are remarkably improved, and the system is particularly suitable for application scenes such as washing machines which are limited in space and need to frequently rotate forwards and backwards.
