Abstract
It the utility model is related to a kind of low inertia rotor structure for permanent magnet motor.The structure taken is：Including front axle (1), magnet steel (2), rear axle (3)；Machine shaft is spliced by front axle (1) and rear axle (3), and magnet steel (2) is using Hallbach structures and is pasted on the outer surface of front axle (1).Structure of the present utility model applies the rotary inertia that motor can be substantially reduced in magneto, and does not influence the performance of motor.
Description
Technical field
The utility model belongs to a kind of motor rotor construction designing technique.
Background technology
Develop with motor, motor construction is more and more compacter.For the dynamic performance requirements more and more higher of motor, this
Motor is required to have very small rotary inertia.At present solution method be by rotor diameter design it is smaller, thus exist with
Lower problem：
1. rotor external diameter diminishes, motor torque reduces, and power output diminishes；
2. rotor external diameter diminishes, motor output shaft is thinner, low intensity；
Utility model content
The purpose of this utility model is：A kind of low inertia rotor structure for permanent magnet motor is proposed, motor rotation can be reduced
Inertia, dynamic property is improved, while do not influence the electromagnetic performance of motor again.
The structure that the utility model is taken is：Including front axle 1, magnet steel 2, rear axle 3；Machine shaft is spelled by front axle 1 and rear axle 3
Connect and form, magnet steel 2 is using Hallbach structures and is pasted on the outer surface of front axle 1.
Preferably, machine shaft is all permeability magnetic material by front axle 1 and rear axle 3.
Preferably, front axle 1 is hollow-core construction.
Preferably, rear axle 3 is hollow-core construction.
Structure of the present utility model applies the rotary inertia that motor can be substantially reduced in magneto, and does not influence
The performance of motor.
Brief description of the drawings
Fig. 1 is the structural representation of the preferred embodiment of the utility model；
Wherein, 1：Front axle, 2：Magnet steel, 3：Rear axle
Embodiment
The utility model is elaborated with reference to Figure of description, referring to Fig. 1, a kind of low inertia of the utility model
Rotor structure for permanent magnet motor.The structure that the utility model is taken is：Including front axle 1, magnet steel 2, rear axle 3；Machine shaft is by front axle 1
Combined with rear axle 3, and front axle 1 and rear axle 3 all use hollow-core construction, and be permeability magnetic material, material 17-4；Magnet steel
2 use Hallbach structures, and are pasted on the outer surface of front axle 1.
Structure of the present utility model applies the rotary inertia that motor can be substantially reduced in magneto, and does not influence
The performance of motor.
