Abstract：A novel moving-magnet type linear oscillatory motor was presented to achieve reciprocating movement with short stroke and high frequency. The linear oscillatory motor is driven by single-phase power with two “C” type external divided stators and without internal stator. It was characterized by compact configuration, easy manufacture and high electromagnetic thrust. Equivalent magnetic circuit method and finite element method were utilized to analyze and deduce the design criterions of the critical parameters. By the proposed experimental test method, the static thrust force and back EMF of prototype were measured. It is shown that the electromagnetic thrust is proportional to the winding current and the electromagnetic thrust coefficient is equal to the back EMF coefficient.
