The present paper examines a permanent-split-capacitor type single-phase induction motor that does not contain a rotor. The stator of this motor is capable of generating an elliptical magnetic field inside the housing by exciting 2-stator windings, a main winding and an auxiliary winding. Magnetic field shape can be varied by changing the value of the capacitor in series with the auxiliary winding. The stator of this motor is referred to as a single-phase magnetic field generator, and the electrical and magnetic characteristics of the generator were investigated. An expression was derived for determining of the magnetic field based on the magnetic circuit of the generator. The derived equation was applied to calculate the Lissajous elliptical magnetic field produced in a prototype magnetic field generator. The calculated results were in good agreement with those obtained experimentally using an oscilloscope to generate the Lissajous patterns. In addition, the calculated value of the magnetic flux density was in good agreement with that measured experimentally using a Gauss meter. Information on a new magnetic barrel finishing machine was obtained from the results of the experiments, and used to manufacture the new machine. This machine has succeeded in finishing various metals with complex shapes.
