Description
Technical field
The present invention is on a kind of syncmotor, especially with regard to a kind of structure of the rotor of syncmotor.
Background technology
Motor is in society now, and no matter industrial or people's livelihood aspect is all indispensable equipment, in horse in recent years
The technology reached is also maked rapid progress, and motor species is various on the market, and compared to other modern age motors, syncmotor is because its rotor is with determining
Sub- rotating excitation field is synchronous rotary, therefore without induced-current, also without secondary copper loss, so with energy conversion efficiency height, system
Journey is simple, be not necessary to separately put into substantial contribution purchase process equipment, the low advantage of production cost.
Syncmotor mainly uses reluctance force to operate, and reluctance force is different from the Lorentz force that general motor is used,
The principle of reluctance force is that when forming a loop in space using the magnetic line of force, the magnetic line of force can select away the minimum road of magnetic resistance
Footpath, so when rotor is placed in stator field, it is minimum position that the magnetic line of force, which can drive rotor movement to magnetic resistance, because rotor main will
It is that rotor slot is formed on rotor, produces magnetic resistance maximum poor with minimum magnetic resistance, and then produces reluctance torque, as shown in figure 1,
For a rotor 90 of syncmotor, the rotor 90 is by a body 91 and is arranged in a main shaft 92 of the body 91 and is constituted, should
The two ends of body 91 have a first end face 911 and a second end face 912, and the first end face 911 extends to the second end face 912
Direction be an axial direction A, the axial direction of body 91 A opens up the perforation 93 of plural strip, the respectively plural link of shaping between the perforation 93
Portion 94, because the body 90 has those perforation 93, makes that the intensity of the structure of syncmotor is weaker, quality is not easy to grasp, and
Applied to higher rotation speed or the application scenario of the big torsion of low speed, the rotor 90 produces shear stress and stretching close at the perforation 93
Stress, makes rotor structure intensity produce problem, or even damage.
What is more, the rotor of syncmotor easily has the missing such as beat, dynamic balancing deviation, to overcome this problem industry just
Develop the mode of several counterweights, it is known that the mode of counterweight is to open up multiple by the linking part 94 of the heavier side of the body 91
Number matches somebody with somebody repeated hole 95, the balanced weight for thereby making the body 91 overall, and only, such a mode easily makes the structure of the rotor 90 more crisp
It is weak, greatly improve the risk of damage.
The content of the invention
The present invention provides a kind of structure of the rotor of syncmotor, and its main purpose is that the structure of enhancing syncmotor is strong
Degree.
Its another object is to provide one kind and avoids damage to motor configuration, you can reach the rotor of the syncmotor of counterbalancing effect
Structure.
For up to object defined above, the structure of the rotor of syncmotor of the present invention, including：
One rotor, the rotor is by a body and is arranged in a main shaft of the body and constituted, and the body has relative
One first end face and a second end face, it is an axial direction that the first end face, which extends to the direction of the second end face, and the body is axially opened
If there is a non-permeable material in the perforation of plural strip, at least one perforation.
Preferably, the non-permeable material of the rotor in heavier-weight side, which opens up one, matches somebody with somebody repeated hole.
From the foregoing it will be appreciated that the structure of the rotor of syncmotor of the present invention is main by setting non-magnetic in those perforation
Material, thereby strengthens the structural strength of syncmotor, and the non-permeable material in the heavier side of the rotor weight opens up this
With repeated hole, motor configuration is avoided damage to reach offer one kind, you can reach the structure of the rotor of the syncmotor of counterbalancing effect
Purpose.
