Study on the Characteristics of Electromagnetic Actuator VT-300

In order to study the non-linearity of the static and dynamic characteristics between the input and output of the electromagnetic actuator, and to provide a basis for the design of the active vibration isolation system, this article took the VT-300 electromagnetic actuator produced by Yangzhou YMC Company as the research object The static and dynamic characteristics between the input and output are studied. The hysteresis characteristics, the phase relationship between the force output of the actuator and the input signal at different input frequencies (sinusoidal signals), and the relationship between the force output and the amplitude of the input signal at the same frequency were studied. A characteristic model of VT-300 electromagnetic actuator was established.
