Abstract—This paper investigates a novel linear oscillating motor for the application of linearly driven hydraulic pump. The motor working principle and special structure was elaborated. Its time-domain, frequency-domain and vector dynamics model are established respectively. And based on the model, the motor resonant frequency characteristic is analyzed. In addition, the influence of dynamic parameters on the resonant frequency characteristic is invested. A resonant capacitor is connected to the coils to compensate the winding inductance, and the motor power factor and mechanical characteristics is researched. At last, the motor power spectrum is acquired to contribute to the dynamics parameters design and optimization.
