Abstract
The breaking and closing operation process of bi-stable permanent magnetic actuator (BPMA) is flexible and controllable, and can achieve the permanent magnet locking effect at the steady-state position. However, during its operation, the breaking and closing air gap electromagnetic and permanent magnet flux linkage are coupled, which will affect the action characteristics of the moving core. Therefore, this article constructs the voltage balance equation of the breaking and closing coils through the equivalent circuit of coil decoupling, and analyzes the parameters that affect the coupling phenomenon; Design a current closed-loop to control the actuator. Through co-simulation of LabVIEW and Multisim, analyze the influence of the electromotive force induced by the coupling phenomenon at each stage of the breaking and closing process, explore the mechanism of the coupling phenomenon, and the impact of the coupling effect on the action process; Finally, experimental waveforms were obtained through an embedded control system, and the accuracy of the simulation was verified by comparing the simulated waveforms. This indicates the reliability of the coupling phenomenon analysis through simulation.
