Problems solved by technology

Most of the traditional disk motor rotors adopt a surface-mounted structure. The magnetic steel of this structure is pasted on the surface of the rotor. Due to the centrifugal force, the surface-mounted structure cannot make the motor run at an excessively high speed, which limits the maximum speed of the motor and reduces the spe

Example

[0046] first embodiment

[0047] like Figure 1 to Figure 7 As shown, the first stopper 400a is integrally formed with the support portion 120 , and the second stopper 500a is detachably connected to the support portion 120 .

[0048] Specifically, refer to Figure 7 , the second blocking member 500a includes a connecting portion 510a and an abutting portion 520a, the connecting portion 510a is connected with the abutting portion 520a, the connecting portion 510a is installed on the supporting portion 120, the The abutting portion 520 abuts on a side of the hoop 300 away from the first blocking member 400a.

[0049] The connecting portion 510a can be sleeved on the supporting portion 120, so that the two are assembled more conveniently and quickly. image 3 and Figure 4 , the side of the support portion 120 away from the first blocking member 400a is provided with a first sleeve hole 121a. When the connecting portion 510a is sleeved in the first sleeve hole 121a, the abut...

[0060] Second Embodiment

[0061] like Figure 8 to Figure 12 As shown, the difference from the first embodiment is that both the first blocking member 400b and the second blocking member 500b are integrally formed with the supporting portion 120 .

[0062] like Figure 10 and Figure 11 As shown, the number of the first stopper 400b and the second stopper 500b are the same, and are disposed on the same support portion 120 in a one-to-one correspondence. Of course, the first blocking member 400b and the second blocking member 500b may be disposed on different supporting portions 120 . For example, in two adjacent supporting portions 120 , one of the supporting portions 120 is provided with a first blocking member 400 b , and the other supporting portion 120 is provided with a second blocking member 500 b.

[0063] Preferably, the plurality of first blocking members 400b and the plurality of second blocking members 500b are arranged at equal intervals along the outer periph...

Example

[0068] Third Embodiment

[0069] like Figure 13 to Figure 17 As shown, the difference from the first embodiment is that both the first stopper 400c and the second stopper 500c are detachably connected to the support portion 120 .

[0070] The first stopper 400c can be fixed on the support portion 120 by a fastener, and the head of the fastener is embedded in a side of the support portion 120 away from the first stopper 400c. refer to Figure 16 , the support portion 120 is provided with the mounting hole 121c through which the fastener passes, and the fastener passes through the mounting hole 121c and is threadedly connected to the first stopper 400c. The second stopper 500c can also be fixed on the support part 120 by a fastener, and the head of the fastener for fixing the second stopper 500c is embedded in the support part 120 away from the first stopper. One side of the second stopper 500c.

[0071] like Figure 16 and Figure 17As shown, the support portion 120 is p...

Abstract

The invention provides a rotor structure of a disc type motor. The rotor structure comprises a rotor disc, a plurality of magnetic steels, a hoop, at least two first blocking pieces and at least two second blocking pieces, wherein the rotor disc comprises a base part and a plurality of supporting parts, the supporting parts extend outwards to the periphery of the base part, the number of the magnetic steels is consistent with that of the supporting parts, and the magnetic steels fixedly extend outwards to the base part and are arranged at intervals with the supporting parts; the hoop is fixedly arranged on the outer periphery of the magnetic steels in a sleeving manner, so that the magnetic steels are fixed between the hoop and the base part; and the first blocking pieces and the second blocking pieces are located on the two sides of the rotor disc respectively, the first blocking pieces and the second blocking pieces are fixed to the supporting parts, so that the hoop is fixedly connected between the first blocking pieces and the second blocking pieces in a clamped mode, the two sides of the hoop are connected with the first blocking pieces and the second blocking pieces in a clamped mode, so that the hoop can be fastened, and the fixing effect of the hoop on the magnetic steels is enhanced.

Description

technical field [0001] The invention relates to the technical field of disk motor rotors, in particular to a rotor structure of a disk motor. Background technique [0002] Due to the characteristics of small size, high power density, short axial dimension, and low life-cycle cost, disc motors can be used in most thin-profile installation occasions. Magnetic steel fixing plays a vital role in the smooth operation and reliability of the motor. . Most of the traditional disc motor rotors adopt a surface-mounted structure. The magnetic steel of this structure is pasted on the surface of the rotor. Due to the centrifugal force, the surface-mounted structure cannot make the motor run at an excessively high speed, which limits the maximum speed of the motor and reduces the speed of the motor. performance. In addition, the method of adhering the magnetic steel on the surface of the rotor has certain potential safety hazards. The glue is prone to deterioration and aging due to time...
