Embodiment
It should be appreciated that specific embodiment described herein is not used to limit this only to explain the utility model
Utility model.
Easy the technical problem to be solved in the present invention is to provide manufacturing process, magnet steel installation is reliable, and position is accurate, product one
The good rotor permanent magnet motor pole structure of cause property.
Reference picture 1 and Fig. 5, a kind of permanent magnet machine rotor of the present utility model, including rotor core 5, tile-shaped magnet steel 2, every
Bar 3 and magnetic steel sleeve 4.The parting bead 3 comprises at least two；The direction of axis of the parting bead 3 along rotor core 5 is arranged at institute
State on rotor core 5；Sipes is formed between parting bead 3, the tile-shaped magnet steel 2 is installed on the sipes；The magnetic steel sleeve 4 is located at institute
State on rotor core 5, wrap up the tile-shaped magnet steel 2.
The mounting means of magnet steel is many in existing process, but most of techniques are cumbersome, and installation is complicated.Therefore this practicality is new
Type fixes method insecure, the workload that not only solves mounting method of tile-type magnet steel installation site by way of setting parting bead
The problem of big, solves the problems, such as interpolation method manufacturing process complexity again.
Reference picture 2, rotor core 5 are provided with mounting hole 6 to fix parting bead 3, and the number of the mounting hole 6 is more than or equal to 2.
The number of mounting hole is more than or equal to 2, is advantageous to strengthen the stability that parting bead 3 is installed.In the present embodiment, the number of mounting hole is 2.
Reference picture 3, every section of parting bead are provided with along 5 axial both sides of rotor core and hide glue hole 8, it is ensured that when running at high speed,
Glue will not be thrown out of.
Reference picture 3, parting bead 3 are provided with locating dowel 7 in the side towards the rotor core 5, and the locating dowel 7 is installed on institute
State in mounting hole 6, the stability that enhancing parting bead 3 is installed.
Reference picture 3 and Fig. 4, every parting bead 3 are at least divided into two sections, and adjacent two sections along around the axial direction of rotor core 5 mistake
Open certain angle setting.In the present embodiment, every parting bead 3 divides for 3 sections.Sipes, the tile-shaped magnet steel are formed between adjacent parting bead 3
2 are installed in the sipes, and the gap formed between each row's tile-shaped magnet steel 2 does not line up in the axial direction.Slot effect adds
The starting reactance of generator, also make it that generator operation is unstable, can reduce the efficiency of generator.In variable speed drives, when turn
When square frequency is consistent with the mechanical resonance frequency of stator or rotor, vibration caused by cogging torque and noise will be exaggerated.Teeth groove
The presence of torque equally have impact on high-precision fixed in low-speed performance and position control system of the motor in speed control system
Position.Using this design, it is possible to the slot effect of motor is effectively reduced, so that motor smooth pivotal, reduces the shake of motor
It is dynamic.The utility model is in use, should also determine the size of each offset angular of row's tile-shaped magnet steel 2 according to specific needs.Permanent Magnet and Electric
The row of the tile-shaped magnet steel 2 of machine is more than or equal to 2, and columns is more than or equal to 2, can be according to reality in order to meet the requirement of power of motor
Border demand is adjusted.In the present embodiment, tile-type magnet steel row is 3, columns 2.
The both ends of magnetic steel sleeve 4 are chamfering or fillet 9, and the chamfering or fillet 9 are coated with dynamic balancing clay 10.Due to a variety of
Reason, such as various component weight differences, material are uneven, manufacture machining tolerance, cast member have burning into sand and loose casting
Defect, so as to produce rotor gyration vector, eccentric force will be produced when rotor operates, unit, which produces, under eccentric force effect shakes
It is dynamic, send noise and cause the damage of the parts such as bearing, shorten the service life of motor.Therefore motor balanced structure for
The life-span of motor is improved, noise etc. is reduced and is particularly important.Reference picture 5, the utility model are subtracted using dynamic balancing clay 10
The gyration vector of lesser trochanter.The both ends shaping of magnetic steel sleeve 4 has chamfering or fillet 9, the chamfering or fillet 9 is coated and is located at sipes side
The dynamic balancing clay 10 on edge.This design can effectively reduce because rotor rotation imbalance and caused by shake, also ensure that balance
Glue will not outwards be thrown away in rotor rotation process, release equivalent risk.The utility model is provided at both ends with fillet magnetic steel sleeve 4
Or chamfering 9, balance clay 10 is placed in fillet or the chamfering 9 of magnetic steel sleeve 4.Using this balance mode, manufacturing cost
Low, technique is simple.
In summary, the utility model proposes permanent magnet machine rotor fix tile-type magnet steel by way of parting bead is set
Installation site, manufacturing process is easy, and magnet steel installation is reliable, and position is accurate, good product consistency；Fixed using magnetic steel sleeve fixed flat
The mode of weighing apparatus clay, balance glue are fixed reliable；Technique is simple, and manufacturing cost is low；Each row's tile-shaped magnet steel staggers certain angle, has
Effect inhibits slot effect.
Preferred embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model,
Every equivalent structure made using the utility model specification and accompanying drawing content or equivalent flow conversion, or directly or indirectly fortune
Used in other related technical areas, similarly it is included in scope of patent protection of the present utility model.
