Optimal Design and Performance Analysis of a New-Type Linear Oscillatory Motor with Three Divided Moving Body

Aiming at solving the problems such as the electromagnetic thrust is too small and the output of electromagnetic thrust is not stable for the existing permanent magnet linear oscillation motor, A new type of permanent magnet linear oscillation motor with three divided moving body was proposed. By analyzing the working principle of permanent magnet linear oscillation motor, the preliminary design of motor structure was carried out. The simulation results show that the structural parameters such as the height of permanent magnet, the length of the secondary permanent magnet, the height of the air gap and the thickness of the inner stator core have great influence on the electromagnetic thrust. Through the optimization design of motor parameters, a new type of three divided moving body permanent magnet linear oscillation motor with large electromagnetic thrust and stable operation was obtained. After optimization, the electromagnetic thrust changes sinusoidally, and the maximum electromagnetic thrust was greatly improved. A new PMLOM control system was built, and the static force was measured.
