Description
Technical field
The present invention relates to a kind of permagnetic synchronous motor, belong to technical field of motors.
Background technology
Chinese patent discloses a kind of " automatic start type synchronous machine and the compressor that uses this motor " (number of patent application: 02132084.5), should " automatic start type synchronous machine " have stator core, be wound on armature coil, rotor core in this stator core, be embedded in magnet and the mouse-cage type winding that is arranged in the above-mentioned rotor core in this rotor core, and above-mentioned armature coil has been made concentrated winding.Above-mentioned " automatic start type synchronous machine " complex structure brings certain degree of difficulty to the manufacturing.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple in structure, permagnetic synchronous motor of being easy to processing.
The technical solution adopted for the present invention to solve the technical problems:
Stator and cage rotor have been the present invention includes, it is characterized in that, cage rotor contains the hybrid rotor axle, the hybrid rotor axle is made up of armature spindle and the paired permanent magnet that is embedded on the armature spindle, armature spindle external diameter after inlaying remains unchanged, rotor core is contained in outside the armature spindle that is inlaid with the permanent magnet position, folded thick the equating of the axial length of permanent magnet and rotor core, the mouse cage group is arranged in rotor core, be provided with the non-magnetic separator between the two adjacent permanent magnets, each non-magnetic separator also separates rotor core simultaneously.
The logarithm of described paired permanent magnet is selected from any in following: 1 pair, 2 pairs, 3 pairs, 4 pairs.

Embodiment
Embodiment 1:
By Fig. 1, embodiment 1 shown in 2 as can be known, it is the four-pole permanent magnet synchronous machine, it includes stator and cage rotor, cage rotor contains the hybrid rotor axle, the hybrid rotor axle is made up of armature spindle 3 and two pairs of permanent magnets 2 that are embedded on the armature spindle, armature spindle external diameter after inlaying remains unchanged, rotor core 1 is contained in outside the armature spindle that is inlaid with the permanent magnet position, folded thick the equating of the axial length of permanent magnet 2 and rotor core 1, the mouse cage group is arranged in rotor core 1, be provided with non-magnetic separator 4 between the two adjacent permanent magnets 2, each non-magnetic separator 4 also separates rotor core 1 simultaneously.
The method for embedding of the permanent magnet of present embodiment is as follows:
(1) on the armature spindle of existing asynchronous machine, choose with respect to the folded thick fragment position of rotor core, this section armature spindle is thin with the lathe car.(see figure 1).
(2) get four duplicate bearing shell shape permanent magnets 2, four permanent magnets 2 are sticked on the good thin axle of car; And between two adjacent permanent magnets, insert non-magnetic separator 4, this separator 4 also separates (see figure 2) with rotor core 1 simultaneously, in Fig. 2, the outer end of separator 4 just contacts with squirrel-cage bar 5, the width unshakable in one's determination in every squirrel-cage bar 5 outsides is very little, therefore, can establish separator more herein.Inlay the whole outer through constant (see figure 1) of four hybrid rotor axles behind the permanent magnet, it is the same with the external diameter of armature spindle of asynchronous machine among Fig. 3.
Embodiment 2: be respectively three kinds of permagnetic synchronous motors of 2,6,8 utmost points.
The paired permanent magnet that three kinds of permagnetic synchronous motors of 2,6,8 utmost points of embodiment 2 representatives are embedded on the armature spindle as different from Example 1 is respectively 1 pair, 3 pairs, 4 to (omitting its structural representation at this).
Claims (2)
1, a kind of permagnetic synchronous motor, it includes stator and cage rotor, it is characterized in that, cage rotor contains the hybrid rotor axle, the hybrid rotor axle is made up of armature spindle and the paired permanent magnet that is embedded on the armature spindle, armature spindle external diameter after inlaying remains unchanged, rotor core is contained in outside the armature spindle that is inlaid with the permanent magnet position, folded thick the equating of the axial length of permanent magnet and rotor core, the mouse cage group is arranged in rotor core, be provided with the non-magnetic separator between the two adjacent permanent magnets, each non-magnetic separator also separates rotor core simultaneously.
