Abstract
The utility model discloses a rotor for three -phase asynchronous motor's self -starting permanent magnet synchronous motor, including rotor core, pivot, cage strip and end links, the cage strip is the just radial equipartition of bar in the rotor core outer fringe, the both ends of cage strip are connected with two end links respectively, and the cross -section matches for curved groove with the cross -section of equipartition on rotor core is global respectively for curved permanent magnet, and the sheath cover is established the rotor core outer peripheral face with on the outer peripheral face of permanent magnet, the sheath is made for electrically conductive not magnetic materials, the lower terminal surface and the contact of cage strip of permanent magnet. The sheath is the stainless steel lantern ring. The utility model has the advantages of the efficient and with low costs is showing.
Description
Technical field
This utility model relates to a kind of motor, the rotor of a kind of self-start permanent-magnet synchronous motor for threephase asynchronous.
Background technology
Existing threephase asynchronous, after being passed through three-phase symmetrical alternating current by threephase stator winding, produce rotating excitation field, this rotating excitation field cutting rotor winding, producing faradic current in rotor windings, the rotor conductor of current-carrying, under stator rotating excitation field effect, produces electromagnetic force, thus on motor rotary shaft, form electromagnetic torque, drive motor to rotate.But existing Three-phase Asynchronous Motor Efficiency is on the low side, makes improvements, make permasyn morot, improve efficiency and there is wide market.
Summary of the invention
This utility model purpose is to provide one and has efficiency height, the rotor of a kind of self-start permanent-magnet synchronous motor for threephase asynchronous of low cost.
The technical solution of the utility model is, a kind of rotor of the self-start permanent-magnet synchronous motor for threephase asynchronous, including rotor core, rotating shaft, cage bar and end ring, it is characterized in that: described cage bar is that bar shaped and radial equipartition are in rotor core outer rim, the two ends of described cage bar are connected with two end ring respectively, cross section is that the permanent magnet of arc matches with the groove that the cross section being distributed on rotor core side face is arc respectively, sheath is set on the outer peripheral face of described rotor core outer peripheral face and described permanent magnet, described sheath is made for conduction non-magnet_conductible material, the lower surface of described permanent magnet contacts with cage bar.Described sheath is the rustless steel collar.
This utility model has the high remarkable advantage with low cost of efficiency compared with the prior art.
Accompanying drawing illustrates:
Fig. 1 is the rotor perspective view of a kind of self-start permanent-magnet synchronous motor for threephase asynchronous of this utility model；Fig. 2 is the A-A profile of Fig. 1.
Detailed description of the invention:
In order to solve the drawbacks described above that prior art exists, this utility model adopts the following technical scheme that, as shown in Figure 1-2, the side face of three-phase asynchronous motor rotor iron core 1 is evenly equipped with four arcuate grooves, the permanent magnet 2 that four cross sectional shapes are arc (shoe) is located in these four arcuate grooves, the degree of depth of described arcuate groove is the most shallow under the conditions of meeting the magnetic of permanent magnet, makes cage bar 6 body in rotor core remain with the biggest conductive area.Fig. 1-2 show the rotor of four pole three phase asynchronous motors, there are 16 cage bars and 4 arc-shaped permanent magnets, described arcuate groove only cuts the part bar body of a cage bar, and the quantity of cut cage bar is few, as in the threephase asynchronous that selects, cage bar is to be radially arranged and during bar shaped that radial dimension is bigger, the part cage bar cut is less to starting influential effect.In addition, in order to make the permanent magnet being located in rotor core arcuate groove not thrown away by centrifugal force when rotor high speed rotating, the sheath 3 using conduction non-magnet_conductible material to make is set on the side face of rotor core and permanent magnet, permanent magnet is fixed, described permanent magnet is axial overall permanent magnet, or the most multiple permanent magnet.The preferred stainless steel band of the non-magnetic sheath of described conduction or the sheath being made up of stainless steel silk, the intensity of this sheath is high and resistance to elevated temperatures is good, and described four arcuate grooves are located in mouse cage two end ring, do not damage end ring.Above-described embodiment is four pole three phase asynchronous motors, it is also possible to be six types of severe debility disease or ends of the earth threephase asynchronous.
Above-mentioned rotor core utilizes existing three-phase asynchronous motor rotor to improve, and rotating shaft 5, fan leaf 4 are not changed, and improvement cost is low, and stator is without changing, and has and start effective and that motor normal course of operation efficiency is high remarkable advantage.
