Description

Technical Field

[0001] This utility model relates to the field of electrical components technology, specifically to a 360° servo motor. Background Technology

[0002] A 360° servo is a continuously rotating servo that can be programmed to control 360° in a single rotation. In normal use, it should be able to rotate to any angle and then return to the specified absolute position after power failure. However, if it is rotated after power failure due to abnormal use, it may not be able to return to the specified absolute position after reset.

[0003] See Figures 1-4 As shown, the existing servo motor 1 drives the servo output shaft 4 through the first reduction gear set. The servo output shaft 4 drives the servo disc 5 to rotate. At the same time, the servo output shaft 4 is connected to the potentiometer 3 through the second reduction gear set, realizing the monitoring of the rotational speed and direction of the servo output shaft 4 by the potentiometer 3. Figures 2-4 As shown, the existing potentiometer 3 has a ring-shaped resistor structure, where region 301A' is the normal operating range of the potentiometer, region 301B' is the maximum operating range of the potentiometer, and region 301C' is the range where the potentiometer has no resistance. Region 301A' (the normal operating range of the potentiometer) occupies 240° of the ring-shaped resistor's angle range. The current solution uses a second reduction gear set with a reduction ratio of 1:1.5 to reduce the 360° rotation angle of the servo motor output shaft 4 to 240° and transmit it to the potentiometer. When the servo motor is normally powered on for control, the potentiometer will... Figures 2-4 Within the range of the servo motor's normal operating range 301A', each of the 360 ​​angles corresponds to a specified value. When the servo motor is powered off, after manually rotating it clockwise more than 360° or counterclockwise more than 22.5°, the sliding contact 302 of the potentiometer enters the potentiometer's zero-resistance range of the annular resistor. Powering on the motor controls the reset. When the sliding contact 302 of the potentiometer resets to the specified absolute position, it will pass through the potentiometer's zero-resistance range. After the angle is amplified by the second reduction gear set, the servo motor's output shaft 4 cannot reset to the specified absolute position, resulting in a positional difference compared to the reset position at any position within the range 301A' (potentiometer's normal operating range).

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0037] See Figure 1 , Figures 5-7 As shown, a 360° servo motor of this embodiment includes:

[0038] Motor 1;

[0039] Servo output shaft 4;

[0040] Potentiometer 3 includes potentiometer shaft 303 and annular resistor 301. The annular resistor includes a normal operating region 301A, and the normal operating region 301A occupies an angle range of 0° to 180° of the annular resistor 301.

[0041] The reduction gear set 2 includes a first reduction gear set and a second reduction gear set. The first reduction gear set is connected to the motor 1 and the servo output shaft 4. The second reduction gear set is connected to the servo output shaft 4 and the potentiometer shaft 303. The reduction ratio of the second reduction gear set is 1:2.

[0042] In this embodiment, a 360° servo uses a second reduction gear set with a reduction ratio of 1:2 to reduce the 360° rotation angle of the servo output shaft 4 to 180° and transmit it to the potentiometer. When the servo is normally powered on, the potentiometer will move within the normal working range 301A shown in the figure. At this time, each of the 360 ​​degrees of the servo output shaft 4 has a corresponding specified value. When the servo is powered off, manually rotating it clockwise or counterclockwise at any angle will result in a power-on reset without error compared to resetting at any position within the normal working range 301A.

[0044] Furthermore, in a 360° servo motor of this embodiment, the annular resistor 301 includes a resistance-free region 301C, which is located between the two maximum working regions 301B.

[0045] As an optional implementation of this embodiment, in a 360° servo motor of this embodiment, the resistance-free area 301C and the maximum working area 301B at both ends occupy an angular range of 180° to 360° of the annular resistor 301.

[0046] As an optional implementation of this embodiment, in a 360° servo motor, the angle percentage of the maximum working area 301B at both ends occupying the annular resistor 301 is greater than or equal to the angle percentage of the non-resistance area 301C occupying the annular resistor 301. Since the normal working area 301A occupies an angle range of 180° in the annular resistor 301 in this embodiment, by appropriately increasing the angle percentage of the maximum working area 301B, the working stability of the potentiometer can be ensured.

[0047] In this embodiment, a 360° servo motor is provided. The potentiometer 3 includes a sliding contact 302 and a sliding contact track (not shown). The sliding contact track is fixedly installed and fitted on the outer periphery of the potentiometer shaft 303. The sliding contact 302 is mounted on the potentiometer shaft 303 and rotates synchronously with it. The sliding contact 302 maintains sliding contact with the annular resistor 301 and the sliding contact track, respectively.

[0048] Furthermore, a 360° servo motor of this embodiment includes a servo disk 5, which is mounted on the servo motor output shaft 4; the servo motor output shaft 4 and the potentiometer shaft 4 are arranged with the same central axis.

[0049] When the 360° servo motor is powered on and working normally, the motor 1 drives the servo disk 5 to rotate 360 ​​degrees through the first reduction gear set and the servo motor output shaft 4. At the same time, the servo motor output shaft 4 drives the potentiometer shaft 303 to rotate through the second reduction gear set. The potentiometer shaft 303 drives the sliding contact 302 to slide in the working area of ​​the annular resistor.

[0050] When the 360° servo motor is powered off, the sliding contact 302 of the potentiometer 3 resets to the absolute position of the potentiometer, and drives the servo disk 5 to reset to the absolute position of the servo disk through the potentiometer shaft 303, the second reduction gear set, and the servo motor output shaft 4.

[0051] In this embodiment of a 360° servo motor, the sliding contact track extends to lead out a sliding contact voltage pin, and the two ends of the normal operating area 301A of the annular resistor 301 respectively extend to lead out a fixed plate voltage pin.

[0052] This embodiment of a 360° servo motor includes a housing 6. The motor 1, the reduction gear set 2, and the potentiometer 3 are all installed inside the housing 6. One end of the servo motor output shaft 4 extends into the housing 6 and is connected to the first reduction gear set, while the other end extends out of the housing 6. The servo disc 5 is installed on the end of the servo motor output shaft 4 located outside the housing 6. One end of the sliding contact voltage pin and the fixed plate voltage pin both extend to the outside of the housing 6.

[0053] A 360° servo motor according to this embodiment includes a control circuit board 7, which is communicatively connected to a motor 1 and a potentiometer 3.

[0054] In this embodiment, a 360° servo motor is described. The control circuit board 7 receives control signals from the signal line, controlling the motor 1 to rotate. The motor 1 drives the first reduction gear set to reduce speed and transmits the signal to the servo output shaft 4. The servo output shaft 4 drives the servo disc 5 to rotate. The servo output shaft 4 and the potentiometer 3 are connected via a second reduction gear set. Simultaneously, the rotation of the servo output shaft 4 drives the potentiometer 3, which outputs a voltage signal to the control circuit board 7 for feedback. The control circuit board 7 then determines the rotation direction and speed of the motor 1 based on its position, thereby achieving a target stop.

[0055] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
