Abstract：To solve the problem that the traditional uniaxial vibrator cannot reproduce the linear-angular space coupling motion,a magnetic circuit structure of an electromagnetic linear-angular vibration exciter that can realize compound vibration is proposed, and the characteristicsits of air-gap magnetic field are analyzed. Firstly, the magnetic circuit and coil structure of the exciter are constructed. An analytical model of the air-gap magnetic field is established based on the equivalent current method,and the maximum relative error with the finite element results is 1.25%, which verified the correctness of the analytical model. Then, the influence of each magnetic circuit parameter on the distribution characteristics of the air-gap magnetic field and the coupling effect between the magnetic field generated by the coil current and the original magnetic field are studied,and the force of the coil during the movement is analyzed. Finally, the prototype of the magnetic circuit topology of the exciter is developed, the linear and the angular vibration air-gap magnetic field are measured,and the maximum relative error between the measured results and the finite element results is less than 5%, which further verifies the effectiveness of the proposed magnetic circuit structure.
