The utility model discloses a drilling subtracts that heavy first dynamic balance end plate is used for heavily dynamic balance with second dynamic balance end plate promptly in order to improve the dynamic balance of rotor on first dynamic balance end plate and second dynamic balance end plate, also is used for the magnet steel axle ascending fixed.
Description
Technical field
The utility model is related to a kind of brushless electric motor rotor dynamic balance structure.
Background technology
For rotating speed rotor high, even there is the eccentric throw of very little, can also cause very big centrifugal force, cause motor
Vibration, produces noise, accelerates the abrasion of bearing, causes rotor part high-cycle fatigue to destroy, and reduces the service life of motor.Cause
This, the dynamic balancing of rotor is in the manufacturing process of motor in occupation of very important status.
The content of the invention
The purpose of this utility model is to provide one kind and can improve dynamically balanced brushless electric motor rotor dynamic balance structure.
To achieve the above object, the utility model is adopted the following technical scheme that：A kind of brushless electric motor rotor dynamic balance structure,
Including the yoke being fixed on armature spindle, the first dynamic balancing end plate and second that is respectively fixed at two ends with of the yoke axial direction moves flat
Weighing apparatus end plate, the first dynamic balancing end plate and the second dynamic balancing end plate are each formed with through hole and are set in rotor by the through hole
On axle, the first dynamic balancing end plate is moved towards a side end face of the second dynamic balancing end plate, the second dynamic balancing end plate towards first
One side end face of balance end plate offsets with yoke, and magnet steel is arranged at yoke outside, and the magnet steel is limited in the first dynamic balancing
Between end plate and the second dynamic balancing end plate, some losss of weight are formed with the first dynamic balancing end plate and the second dynamic balancing end plate
Hole.
The utility model drills loss of weight to improve rotor by the first dynamic balancing end plate and the second dynamic balancing end plate
Dynamic balancing, the first dynamic balancing end plate and the second dynamic balancing end plate are, for duplicate removal dynamic balancing, to be also used for the fixation on magnet steel axial direction,
Prevent magnet steel from dropping out.Wherein, the size and location of lightening hole is selected as needed.
Preferably, the first dynamic balancing end plate and the second dynamic balancing end plate with armature spindle interference fit.It is above-mentioned to set
Put the fixation for the first dynamic balancing end plate and the second dynamic balancing end plate.
Preferably, the magnet steel is in shoe structure, some magnet steel are spliced to form loop configuration, the magnet steel inwall and institute
State yoke wall contacts.
Preferably, the first dynamic balancing end plate and the second dynamic balancing end plate are set in a ring, described first is dynamic flat
Weighing apparatus end plate external diameter size, the second dynamic balancing end plate external diameter size, the external diameter size of annular magnetic steel are identical.In above-mentioned setting, magnet steel
Offseted with the first dynamic balancing end plate, the second dynamic balancing end plate along the position of armature spindle axial direction, to ensure magnet steel axial direction
Spacing fixation, while the first dynamic balancing end plate and the second dynamic balancing end plate lighter in weight, to ensure dynamic balancing effect.
The utility model has the advantages that to improve dynamic balancing, magnet steel is fixed.
