In order to greatly improve the speed ratio of permanent magnet synchronous motor of NC machine tool, it was proposed to winding series-parallel exchange scheme in this paper. This paper discussed the realization method of winding series-parallel switching of permanent magnet synchronous motor. It was analyzed that series-parallel switching causes the change of motor parameters and performance in theory. The experimental platform was set up. The experiment and analysis in current,voltage,torque,etc,was realized for windings of series,parallel,series-parallel switching motors. The experiment showed that under the condition of the process permit, the winding series-parallel switching is one of the effective methods to extend the operating range.
