Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor with a Hall encoder. Background Art

[0002] A Hall encoder is a sensor that converts the mechanical geometric displacement on the output shaft into pulses or digital quantities through magnetoelectric conversion.

[0003] The Hall element is welded to the encoder, and the encoder is welded to the electrode of the motor. There is still the following problem. When welding the encoder to the motor, the staff needs to pay special attention to the position of the encoder. During the welding process, it is easy to bend the encoder. When the encoder is bent, the distance between the Hall element and the disk cannot be controlled. Therefore, after welding the encoder, the staff often needs to correct the position of the Hall element to ensure that the distance between the Hall element and the disk is the preset distance.

[0036] Please refer to Figure 1-Figure 5 , a motor with a Hall encoder, comprising a motor 1, an encoding disk 2, a Hall element 3, a magnetic disk 4 and a fixing part 5;

[0037] The fixing member 5 is installed on the motor 1;

[0038] One end surface of the encoding disc 2 abuts against one end surface of the fixing member 5, and the encoding disc 2 passes through the fixing member 5 and is welded to the electrode 101 of the motor 1, so that the encoding disc 2 is electrically connected to the motor 1;

[0039] The fixing member 5 is provided with at least two positioning posts 501 , and the encoding disc 2 is provided with a positioning hole 201 , and the positioning posts 501 are inserted into the positioning hole 201 ;

[0040] The tail shaft of the motor 1 passes through the fixing member 5 and the encoding disk 2 and is connected to the magnetic disk 4;

[0041] The Hall element 3 is welded to the encoding disk 2 and corresponds to the magnetic disk 4 .

[0042] In this embodiment, the fixing member 5 supports the code disk 2 and ensures that the code disk 2 is on a horizontal surface. Furthermore, the positioning posts 501 on the fixing member 5 are inserted into the positioning holes 201 of the code disk 2, ensuring that the code disk 2 does not move on the horizontal surface. Furthermore, the provision of the fixing member 5 facilitates welding the code disk 2 to the electrode 101 of the motor 1. The worker only needs to place the code disk 2 against the fixing member 5 to directly begin welding, without the need for additional calibration of the code disk 2. This ensures that the code disk 2 is in a horizontal position after welding.

[0043] Furthermore, a clamping member 6 is provided on the fixing member 5 , and the Hall element 3 is mounted on the clamping member 6 .

[0044] Furthermore, the clamping member 6 includes a connecting portion 601 and a slot portion 602 , the first end of the connecting portion 601 is mounted on the fixing member 5 , and the second end of the connecting portion 601 is connected to the slot portion 602 ; the Hall element 3 is clamped into the slot portion 602 .

[0045] Furthermore, the second end of the connecting portion 601 is bent, so that the distance between the slot portion 602 and the magnetic disk 4 is a preset distance.

[0046] Furthermore, the slot portion 602 penetrates vertically, and an opening is provided at one end of the slot portion 602 facing the magnetic disk 4 .

[0047] Furthermore, the fixing member 5 and the clamping member 6 are integrally formed.

[0048] In this embodiment, by providing a fixing member 5, the Hall element 3 is snapped into the slot portion 602 of the fixing member 5, and the distance between the slot portion 602 and the magnetic disk 4 is fixed. Therefore, when the Hall element 3 is snapped into the slot portion 602, the distance between the Hall element 3 and the magnetic disk 4 is also fixed. At this time, the distance between the Hall element 3 and the magnetic disk 4 is a preset optimal distance. When the Hall element 3 and the magnetic disk 4 are in close contact or the distance between the Hall element 3 and the magnetic disk 4 is too large, the Hall element 3 will lose its function. This also facilitates processing by the staff, who do not need to additionally calibrate the distance between the Hall element 3 and the magnetic disk 4.

[0049] Furthermore, a gearbox 7 is connected to the motor 1 .

[0050] Furthermore, a protective cover 8 is provided on the motor 1 , and a protective space is formed between the motor 1 and the protective cover 8 , and the encoding disk 2 , the Hall element 3 , the magnetic disk 4 and the fixing member 5 are all located in the protective space.
