The utility model relates to a sinusoidal wave air gap field PMSM of rotor ideal belongs to permanent -magnet machine, in the structure including the stator and with the stator correspond the setting the rotor, the inboard periphery of stator be provided with the stator tooth, the periphery of rotor on the magnetic pole that should set up with the stator pole pair for the N utmost point and the extremely alternative rotor end terminal that sets up of S, the stator forms the air gap with the rotor pole piece spacing, characteristics are unique design of the bounding line of antitrochanter magnetic structure and end terminal. The utility model discloses a principle is feasible in theory, and it is also uncomplicated to implement technology, proves that sinusoidal wave air gap field PMSM of rotor ideal can eliminate all odd harmonics according to the model machine contrast test result of this scheme preparation, and than existing rotor square wave air gap field PMSM superior performance in general use, the elect
