Permanent magnet synchronous motor

A purpose of the present invention is providing a permanent magnet synchronous motor rotor structure which has high air gap flux density and is easy to generate back electromotive force with a sine wave. In a permanent magnet synchronous motor, a circumferential surface of the rotor is uniformly provided with a plurality of magnetic steel grooves which are independently enclosed and do not contact mutually. Every two magnetic steel grooves are arranged to form a V shape, an opening of the V shape faces excircle of the rotor, and a tip of the V shape faces a rotor center. Each magnetic steel groove is provided with magnetic steel. In each group of V-shaped magnetic steel grooves, two magnetic steel facing the excircle of the rotor core have a same magnetic pole, and magnetic poles of magnetic steel facing the excircle of the rotor core in two adjacent groups of V-shaped magnetic steel grooves are opposite with the magnetic pole of the two magnetic steel. The excircle of the rotor goes down toward the center with depth delta and smooth transition at a crossing position of axes, which means that air gap width at the crossing position is less than air gap width at a straight axis position by delta. Through improving the rotor, the permanent magnet synchronous motor rotor has high mechanical strength and a large salient pole ratio, and weakened magnetism speed expansion is facilitated.
