要約(日本語): This study presents a simple design method and motion control method of 3-degree of freedom (DOF) linear resonant actuators (LRAs) with symmetrical 4-phase coils. First of all, the operation principle of the 3-DOF LRA that resonates with mechanical spring is introduced. Basically, force vectors of this structure can be expressed in 8-directions due to 4-phase symmetric characteristics. By using these vectors, various resonance motions can be realized in the X-Y-Z-space. The effectiveness of the proposed 3-DOF LRA based on symmetric structure with 4-phase is verified through the finite element analysis (FEA) results.
