Abstract
The invention discloses a self-starting permanent magnet synchronous motor rotor comprising a rotating shaft, a rotor iron core, squirrel cage end rings, internal cage strips and permanent magnets. The permanent magnets are matched with axial slots evenly distributed on the circumferential surface of the rotor iron core. External cage strips of which the cross section is conical are matched with the conical slot ports of the axial slots arranged on the circumferential surface of the rotor iron core. The internal cage strips are evenly distributed on the edge of the rotor iron core between the permanent magnets. The two ends of the internal cage strips and the two ends of the external cage strips are respectively connected with the squirrel cage end rings. The self-starting permanent magnet synchronous motor rotor has substantial advantages that operation efficiency is high in normal operation and the starting effect is great.
Description
Technical field:
The present invention relates to a kind of motor, particularly the rotor of self-start permanent-magnet synchronous motor.
Background technology:
Existing self-start permanent-magnet synchronous motor, permanent magnet is generally located in the rotor core between cage bar and rotating shaft, and its defect is distant between permanent magnet and stator, and when motor start-up enters normal operation, operational efficiency is lower, and power consumption is large.When permanent magnet moves to the outer peripheral face of rotor core, when especially the horizontal chi of permanent magnet is larger, cage bar need be located at the below of permanent magnet, and the distance between cage bar and stator increases, and starts effect bad.
Summary of the invention:
The present invention seeks to design a kind of rotor starting the self-start permanent-magnet synchronous motor that operational efficiency is high when effective and motor proceeds to normal course of operation.
The technical scheme realizing the object of the invention is, the rotor of self-start permanent-magnet synchronous motor, comprise rotating shaft, rotor core, cage ring and interior cage bar and permanent magnet, it is characterized in that: described permanent magnet and the axial groove be distributed on rotor core side face match, cross section is that the conical rebate of axial groove on the outer cage bar of taper and described rotor core side face matches, described interior cage bar is distributed on the rotor core outer rim place between permanent magnet, and the two ends of described interior cage bar are connected with cage ring respectively with the two ends of outer cage bar.Described permanent magnet is bar shaped and radial direction is arranged in the axial groove on rotor core side face.
When the present invention not only normally runs compared with the prior art, operational efficiency is high and start effective remarkable advantage.
Accompanying drawing illustrates:
Fig. 1 is the rotor perspective view of self-start permanent-magnet synchronous motor of the present invention; Fig. 2 is the A-A profile of Fig. 1.
Embodiment:
The present invention is the above-mentioned defect solving prior art existence, adopts following technology, as shown in Figure 1-2.The number of poles of motor of the present invention is 8 grades, also 8 grades or be less than 8 poles can be greater than, when number of poles is more, permanent magnet adopts bar shaped and radial setting, larger area is occupied in circumference when avoiding permanent magnet to be watt shape, cause cage bar to be located at the below of permanent magnet 5, make the distance between cage bar and stator increase and affect the effect of motor start-up.Permanent magnet of the present invention and eight axial grooves be distributed on rotor core 3 side face match, the upper port of described axial groove is for upper end is little and the large bell in lower end, cross section is that the outer cage bar 4 of taper matches with described bell, in addition cage bar conduction and non-magnetic brass or stainless steel material are made, in addition the two ends of cage bar are connected with two end ring 2 of mouse cage respectively, remaining 24 interior cage bars 6 are distributed between eight permanent magnets, and interior cage bar is located at as far as possible the outer rim place of rotor core 3, make the distance between itself and stator minimum, thus, rotor of the present invention has and starts Be very effective and the good remarkable advantage of operational effect.Above-mentioned outer cage bar also has the effect preventing permanent magnet from throwing away.Rotating shaft 1 drives rotor core by key.
