The invention provides a rotor structure and a motor. The rotor structure comprises a rotor body and a plurality of magnetic bodies. The rotor body comprises a rotor yoke part and a plurality of rotor salient poles, the rotor salient poles are arranged on the outer circumferential surface of the rotor yoke part, and the plurality of rotor salient poles are arranged at intervals along the circumferential direction of the rotor yoke part; a mounting groove is formed between every two adjacent rotor salient poles; the magnetic bodies are arranged in the mounting grooves, and the plurality of magnetic bodies and the plurality of rotor salient poles are alternately arranged; grooves are formed in the side faces, making contact with the magnetic bodies, of the rotor salient poles. The motor comprises the rotor structure. The grooves are formed in the side faces, making contact with the magnetic bodies, of the salient poles of the rotor, magnetic leakage can be reduced, the sine degree of air gap flux density can be improved, the use amount of the magnetic bodies is reduced, meanwhile, counter electromotive force is effectively improved, the harmonic content of the counter electromotive force is reduced, and the operation performance of the motor can be improved, such as torque pulsation and noise reduction.

The invention relates to an adjustable damping valve device, comprising an actuator with an excitation coil and a valve armature, wherein the valve armature is movably supported in a sleeve-like yoke body, wherein the yoke body has a pole disc on the bottom side, which is arranged position-fixed relative to the valve housing, wherein an emergency operation valve body is switched between an emergency operation state and a normal operation state depending on the power supply of the excitation coil, wherein the emergency operation valve body is switched by a force caused by the magnetic flux of the excitation coil through the yoke body and the pole disc, wherein a magnetic resistance is arranged between the pole disc and the valve housing, wherein the magnetic resistance is generated by an additional magnetic field outside the magnetic field of the excitation coil.
