All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, a compatible permanent magnet ac motor rotor disclosed by the present invention specifically includes:

the rotor comprises a rotor body 1, wherein the rotor body 1 mainly comprises a magnetic steel groove 2, a locking short circuit aluminum strip groove 3, a rotor sheet shaft hole 4 and a rotor fixed shaft convex key 5.

In order to further optimize the above technical solution, the rotor body further comprises a vent hole 6 and a positioning hole 7.

In order to further optimize the technical scheme, the magnetic steel grooves are placed in an inverted splayed shape; the vent hole is arranged close to the upper end of the magnetic steel groove, positioning holes are respectively arranged on two sides of the vent hole, and the positioning holes are screw holes or rivet holes; the magnetic steel groove and the locking short circuit aluminum strip groove are embedded together at intervals, the magnetic steel groove is installed in the region between two thirds and four fifths of the same pole, and the locking short circuit aluminum strip groove is installed in the region between one third and one fifth of the same pole.

In order to further optimize the technical scheme, the magnetic steel grooves are arranged in a shape like a Chinese character 'ba'.

In order to further optimize the technical scheme, the rotor body is formed by stamping high-quality silicon steel sheets

In order to further optimize the technical scheme, the magnetic steel slots in the same polarity can be in a special shape or one or more magnetic steel slots are designed by the edge of the rotor sheet, and if the magnetic steel slots in each polarity are more than one magnetic steel slot, the magnetic steel slots can be arranged in an inverted splayed shape or a straight or regular splayed shape. And each polarity of the rotor sheet adopts a design concept that the middle is large and the two sides are small, so that the magnetic field density between the permanent magnet rotor and the rotating magnetic field stator is enhanced, the gap air gap window between the stator and the rotor is increased, and the area of magnetic heat generation between the rotating permanent magnet field and the stator is reduced.

In order to further optimize the technical scheme, after a stamping die compatible with the permanent magnet alternating current motor rotor is manufactured, high-quality silicon steel sheets (preferably high-quality cold rolled silicon steel sheets with the thickness of 0.35 mm or less) are adopted to be punched into a plurality of compatible permanent magnet alternating current motor rotor sheets, then a plurality of compatible permanent magnet alternating current motor rotor sheets are overlapped and fixed together through fastening bolts or rivets to form the required compatible permanent magnet alternating current motor rotor core (of course, the rotor made of better magnetic conduction and demagnetization materials has better performance), then, permanent magnets (magnetic steels) with different pole directions required by the number of poles, locking short circuit aluminum strips and aluminum balance guard plates (the locking short circuit aluminum strips and the aluminum balance guard plates can be made of aluminum or copper and other materials with good conductivity) are arranged, and (5) compacting by a screw or a tooling press, and finally loading an upper shaft and the rotor fan blade (such as a general assembly drawing). The well-made compatible permanent magnet alternating current motor rotor can be assembled in a matched motor combination after the dynamic balance is adjusted.
