Abstract
The utility model discloses a permanent magnet synchronous motor rotor with the advantages of stable performance, large starting torque and less loss. The permanent magnet synchronous motor rotor comprises a rotating shaft (1), a rotor yoke (3) and permanent magnets (4), wherein the rotating shaft (1) penetrates the center of the rotor yoke (3) and is fixedly assembled with the rotor yoke (3), the permanent magnets (4) adopt strip-shaped permanent magnets which are uniformly distributed in the radial direction on the outer circumference of the rotor yoke (3) and extend in the axial direction, a rotor clamp ring (6) is sleeved at the periphery of the rotor yoke (3), and the rotor clamp ring (6) is used for fixing the strip-shaped permanent magnets on the outer circumference of the rotor yoke (3). The utility model is widely applied to the field of motors.
Description
Technical field
The utility model relates to a kind of permanent-magnetic synchronous motor rotor.
Background technology
The permanent magnet of existing drive motors is to adopt bonding mode evenly to be fixed on the outer surface of rotor mostly, but aging easily loosening under situations such as high temperature, vibrations, and motor performance is descended; Shortcomings such as the rotor of present in addition permagnetic synchronous motor adopts flume structure, and supporting with it stator adopts the straight trough structure, and such structure exists starting torque little, and loss is big.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of stable performance, starting torque is big, loss is little permanent-magnetic synchronous motor rotor are provided.
The technical scheme that the utility model adopted is: the utility model comprises rotating shaft, rotor yoke and permanent magnet, described rotating shaft is passed the rotor yoke center and is assembled with described rotor yoke is fixing, described permanent magnet is the strip-shaped permanent-magnet body, described strip-shaped permanent-magnet body radially is evenly distributed on the outer circumference surface of described rotor yoke, and is and extends axially; Also be socketed with a rotor outer straining ring in described rotor yoke periphery, described rotor outer straining ring is fixed on the strip-shaped permanent-magnet body on the outer circumference surface of rotor yoke.
Evenly be provided with some stopper slots on the outer circumference surface of described rotor yoke, described strip-shaped permanent-magnet body is assemblied in the described stopper slot.
Described permanent-magnetic synchronous motor rotor also comprises the rotor end plates that is fixed on two ends, and described rotor end plates is fastened on the end face of described rotor yoke by screw.
The cross section of described rotor yoke is the hollow structure of " worker " font.
The beneficial effects of the utility model are: because the utility model comprises rotating shaft, rotor yoke and permanent magnet, described rotating shaft is passed the rotor yoke center and is assembled with described rotor yoke is fixing, described permanent magnet is the strip-shaped permanent-magnet body, described strip-shaped permanent-magnet body radially is evenly distributed on the outer circumference surface of described rotor yoke, and be and extend axially, increased starting torque like this, help the asynchronous starting operation of pulling in, stator that can skewed slot during application is supporting, reduces loss; Also be socketed with a rotor outer straining ring in described rotor yoke periphery; described rotor outer straining ring is fixed on the strip-shaped permanent-magnet body on the outer circumference surface of rotor yoke; it is oxidized to protect internal rotor to prevent, can also guarantee permanent magnet exact position on circumference, guarantees that motor properties is stable.

Fig. 2 is along the cutaway view of A-A direction among Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises rotating shaft 1, rotor yoke 3 and permanent magnet 4, described rotating shaft 1 is passed rotor yoke 3 centers and is fixed assembling with described rotor yoke 3, described permanent magnet 4 is the strip-shaped permanent-magnet body, described strip-shaped permanent-magnet body radially is evenly distributed on the outer circumference surface of described rotor yoke 3, and be and extend axially, the strip-shaped permanent-magnet body generally adopts rare earth material; Also be socketed with a rotor outer straining ring 6 in described rotor yoke 3 peripheries, described rotor outer straining ring 6 is fixed on the strip-shaped permanent-magnet body on the outer circumference surface of rotor yoke 3.
Described permanent-magnetic synchronous motor rotor also comprises the rotor end plates 5 that is fixed on two ends, and described rotor end plates 5 is fastened on the end face of described rotor yoke 3 by screw 7.Evenly be provided with some stopper slots 8 on the outer circumference surface of described rotor yoke 3, described strip-shaped permanent-magnet body lacks shape or arc for circle, and close fit and is adhesively fixed by bonding agent in described stopper slot 8, can certainly adopt screw or other modes to fix.Cooperate with the stator with flume structure during application, can reduce the wastage, the integrated power-saving effect is obvious.
In addition, the cross section of described rotor yoke 3 is the hollow structure of " worker " font, has both saved material, has reduced cost, the more important thing is the quality that has alleviated motor, has improved quality than power, has improved the performance index of motor integral body.
Claims (4)
