Overview

Randomized trial analyzes the operational characteristics of AC electromagnetic actuators, suggesting optimal phases for performance.

Key Points

  • The study aims to analyze the electrical–magneto–mechanical coupling characteristics of AC electromagnetic actuators.
  • Applied finite-element method (FEM) and mesh deformation technique using COMSOL Multiphysics.
  • Established an experimental platform to measure magnetic force and validate simulation results.
  • Investigated the effect of coil voltage phase angle on dynamic operational characteristics.
  • The normalized root mean square errors between simulated and measured magnetic forces were below 8%.
  • The study determined the recommended operating window for the actuator's coil voltage phase angle.
  • Found correlations between magnetic force, air gap, and time-varying magnetic force curves.
