Embodiment 1

[0033] as attached figure 1 , 2 As shown, the stator coil and the permanent magnet rotor adopt a cylindrical structure.

[0034] Split type high-speed motor, including shaft 1, permanent magnet rotor 2, stator coil 3, bearing 10 and housing 5, stator coil 3 is fixed to the housing through bracket 8, permanent magnet rotor is fixed to the shaft, and the stator coil adopts ironless coil And it is a concentrated winding, and it can also be a hollow cup winding. In the housing, the rotor is divided into two parts, each part is composed of a permanent magnet rotor and an outer magnetic cylinder. The two parts of the rotor are symmetrically distributed in the cross section of the middle of the shaft; the two outer The openings of the magnetic tubes are arranged facing each other and placed in the middle of the motor. The bottom surfaces of the two outer magnetic tubes are respectively placed at the two end covers 4 close to the casing; the two outer magnetic tubes form a cavity; th...

Embodiment 2

[0039] Such as Figure 5 As shown, on the basis of Embodiment 1, the positions of the stator coil and the permanent magnet rotor are exchanged, the stator coil is on the inside and close to the shaft, the permanent magnet rotor is relatively outside and away from the shaft, and the stator coil is surrounded by the permanent magnet rotor;

[0040] Between the stator coil 3 and the shaft 1 there is also an inner magnetic tube 9, the inner magnetic tube, the permanent magnet rotor and the outer magnetic tube are fixed on the shaft through the connection part, and the three rotate together with the shaft. In this structure, the inner magnetically permeable cylinder can also adopt common magnetically permeable materials.

[0041] The stator coil 3 is located in the gap between the permanent magnet rotor 2 and the inner magnetically permeable ring cylinder 9 .

[0042] Other structures are the same or similar to the embodiment.

Embodiment 3

[0044] Such as Figure 6 As shown, the difference from Example 1 is that the direction of the two outer magnetic tubes is reversed, that is, the bottom surfaces of the two outer magnetic tubes face away from the middle of the motor, and the openings of the two outer magnetic tubes are respectively placed on the two end covers near the case.

[0045] The stator coil is also divided into two parts, and the two parts of the stator coil are also symmetrically distributed according to the radial cross-section of the middle part of the shaft. The end edges of the two parts of the stator coil are fixedly connected to the end cover through the bracket.

[0046] In the inner side of the end cover, the end of the cylindrical permanent magnet rotor is also provided with a conductive disk body 7, and the conductive disk body is fixed with the end cover 4 and can also be fixed with the shaft.

[0047] Other structures are the same or similar to Embodiment 1.

Abstract

Disclosed is a split type high-speed motor. The split type high-speed motor comprises a shell, a stator coil, permanent magnet rotors, outer magnetic conducting cylinders and a shaft, wherein the stator coil and the shell are fixed; the permanent magnet rotors and the shaft are fixed; the stator coil adopts an iron-core-free coil; the stator coil and the permanent magnet rotors adopt a cylindric-shaped structure; each outer magnetic conducting cylinder adopts a cylindric shape with a bottom surface at one end and an opening in the other end; in the shell, the stator coil and a rotor are positioned in a hollow cavity of each outer magnetic conducting cylinder; each permanent magnet rotor is divided into two parts which are symmetrically distributed along the radial section of the shaft; the stator coil also can be divided into two parts which are also symmetrically arranged along the radial section of the shaft to be fixed on the motor shell through a bracket; the iron-core-free coil and / or each permanent magnet rotor is set into a split type; and each group of rotors or stators are symmetrically arranged. On the basis of the structural shape of the existing motor, the lengths of the rotors and the stators are increased, so that the output power is improved and the problem of limited power increasing of the high-speed motor is solved; and in addition, the high-speed motor is simple in manufacturing, relatively low in cost, reliable in operation and high in power.

Description

technical field [0001] The invention relates to a high-speed motor, in particular to a motor without an iron core coil using a split rotor. Background technique [0002] At present, motors are generally composed of stator coils containing iron cores and rotors, and the rotors are generally of two types: squirrel-cage type and permanent magnet type. In addition, high-speed motors have always been high-speed motors with higher revolutions and higher frequencies. The higher the frequency, the greater the high-frequency loss of the iron core, and the low-frequency inductance is determined by the characteristics of the existing iron core. [0003] The existing device has the following shortcomings: due to the existence of high-frequency iron loss and copper loss, the higher the speed of the existing high-speed motor, the lower the efficiency, the more serious the heat generation, the stronger the magnetic field of the permanent magnet motor, the greater the eddy current generated...
