Description
Technical field
The utility model relates to rapid door machine technical field of motors more particularly to a kind of quick door machine permanent magnet synchronous motors.
Background technique
Motor includes stator and rotor, and the magnetic shoe on rotor in traditional technology is usually to be directly bonded on outside rotor core
On cylindrical surface, during rotor high-speed rotation, it is easy to happen the phenomenon that magnetic shoe falls off, influences the normal work of motor.Meanwhile
What magnetic shoe generallyd use is made of rare earth material, and resource is limited, and price is high, substantially increases the cost of motor.
Utility model content
Utility model provides a kind of quick door machine permanent magnet synchronous motor, at low cost, compact-sized, and stability is high.
In order to reach the purpose, utility model is adopted the following technical scheme that
A kind of quick door machine permanent magnet synchronous motor including the rotor on the outside of motor housing, shaft and the shaft and is determined
Son, it is characterised in that: the rotor includes iron core, and the iron core is equipped with bore, and the iron core side is circumferential along the shaft
Several magnetic slots are uniformly provided with, the iron core both ends are equipped with bracket, and the bracket includes the end plate and ring vertical with the shaft
Around the baffle ring of the iron core.
As a preference, the baffle ring is equipped with protrusion, the protrusion is located in the magnetic slot.
As a preference, the bore cross sectional shape is V-arrangement, v-shaped opening side is arranged towards the magnetic slot.
As a preference, the iron core by punching superposition press, the punching be equipped with formed the bore with
The opening of the magnetic slot.
As a preference, the end plate is equipped with screw hole, the rack screw is fixed on the iron core.
As a preference, being equipped with FERRITE CORE in the bore.
As a preference, the baffle ring is equipped with layer of polyester fiber close to the iron core side.
To sum up, compared with prior art, be the advantages of utility model: settable ferrite magnetic steel in magnetic slot reduces
Cost；Baffle ring avoids magnet steel from flying out, and the protrusion on baffle ring is stuck in magnetic slot, avoids bracket from loosening together with the screw on end plate；
Baffle ring is equipped with layer of polyester fiber close to iron core side, and layer of polyester fiber plays the role of buffering between baffle ring and iron core, subtracts
Small abrasion simultaneously reduces noise.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Label in figure is as follows:
1. shaft, 2. rotors, 21. iron cores, 211. bore, 212. magnetic slots, 3. brackets, 31. end plates, 32. baffle rings, 321. is convex
It rises, 33. layer of polyester fiber.
Specific embodiment
Middle embodiment is described further utility model with reference to the accompanying drawing.
A kind of quick door machine permanent magnet synchronous motor as shown in Figure 1, including 1 outside of motor housing, shaft 1 and shaft
Rotor 2 and stator, stator are located at 2 outside of rotor, and shell is located on the outside of stator.Rotor 2 includes iron core 21, and iron core 21 is equipped with magnetic
Hole 211,21 side of iron core are circumferentially uniformly provided with several magnetic slots 212 along shaft 1, and 21 both ends of iron core are equipped with bracket 3, and bracket 3 includes
The baffle ring 32 of the end plate 31 and wound core 21 vertical with shaft 1.End plate 31 is equipped with screw hole, and 3 screw of bracket is fixed on
On iron core 21.Baffle ring 32 is equipped with protrusion 321, and protrusion 321 is located in magnetic slot 212.Settable ferrite magnetic steel in magnetic slot 212,
It reduces costs；Baffle ring 32 avoids magnet steel from flying out, and the protrusion 321 on baffle ring 32 is stuck in magnetic slot 212, with the screw on end plate 31
One works to avoid the loosening of bracket 3.Protrusion 321 is located on baffle ring 32 close to 21 middle part side of iron core, 321 side surface of baffle ring with
The fitting of 212 side surface of magnetic slot.
211 cross sectional shape of bore is V-arrangement, and the opening of V-arrangement bore 211 is arranged towards magnetic slot 212, the cross sectional shape of bore 211
It can also be U-shaped, magnetic slot 212 is between bore 211 and iron core side surface.Magnet steel in magnetic slot 212 can collect magnetic in bore 211
