Abstract
The utility model discloses a self -starting permanent magnet synchronous motor's rotor, including pivot, rotor core, cage ring and interior cage strip and permanent magnet, permanent magnet and the axial groove of equipartition on rotor core is global match, the cross -section be conical outer frame strip and the toper notch in the axial groove on rotor core is global matches, the rotor core outer fringe department of interior cage strip equipartition between the permanent magnet, the both ends of interior cage strip and the both ends of outer frame strip are connected with the cage ring respectively. The utility model discloses not only operating efficiency high and start the effectual advantage that is showing during normal operating.
Description
Technical field:
This utility model relates to a kind of motor, the particularly 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 it is distant that it has the drawback that between permanent magnet and stator, and when motor start-up enters normal operation, operational efficiency is relatively low, and power consumption is big.When permanent magnet moves to the outer peripheral face of rotor core, when especially the horizontal chi of permanent magnet is bigger, cage bar need to be located at the lower section of permanent magnet, and the distance between cage bar and stator increases, and starts effect bad.
Summary of the invention:
This utility model purpose is that design is a kind of to be started effective and motor and proceeds to the rotor of the high self-start permanent-magnet synchronous motor of operational efficiency during normal course of operation.
The technical scheme realizing this utility model purpose is, the rotor of self-start permanent-magnet synchronous motor, including rotating shaft, rotor core, cage ring and interior cage bar and permanent magnet, it is characterized in that: described permanent magnet matches with the axial groove being distributed on rotor core side face, cross section is that the outer cage bar of taper matches with the conical rebate of the axial groove on described rotor core side face, described interior cage bar is distributed on the rotor core outer rim place between permanent magnet, the two ends of described interior cage bar and the two ends of outer cage bar and is connected with cage ring respectively.Described permanent magnet is bar shaped and is radially arranged in the axial groove on rotor core side face.
When this utility model is not only properly functioning 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 this utility model self-start permanent-magnet synchronous motor；Fig. 2 is the A-A profile of Fig. 1.
Detailed description of the invention:
This utility model is solve the drawbacks described above that prior art exists, and adopts following technology, as shown in Figure 1-2.The number of poles of this utility model motor is 8 grades, can also more than 8 grades or less than 8 poles, when number of poles is more, permanent magnet adopts bar shaped and is radially arranged, permanent magnet is avoided to occupy larger area in circumference when being shoe, cause that cage bar is located at the lower section of permanent magnet 5, make the increase of the distance between cage bar and stator affect the effect of motor start-up.Permanent magnet of the present utility model matches with eight axial grooves being distributed on rotor core 3 side face, the upper port of described axial groove is the big bell in lower end for upper end is little, the outer cage bar 4 that cross section is taper matches with described bell, in addition cage bar conduction and non-magnetic pyrite 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 utility model has the startup remarkable advantage that effect is notable and operational effect is good.Above-mentioned outer cage bar also has the effect preventing permanent magnet from throwing away.Rotating shaft 1 drives rotor core by key.
