For example, the height of the sensor is the height of the

rotating body

20 plus a part of the height of the

motor

plate

21. The

motor

10 is positioned between the two

side plates

22 and is fixedly connected with the middle part of the

middle connecting plate

21 through the

rotor

12. The

motor

10 is located between the two

side plates

Referring to fig. 4 and 5, in an achievable embodiment of the invention, the

electrical machine

10 further comprises a

housing

13, the

housing

13 having a receiving cavity which is open at one end. The

stator

11 is connected with the

shell

13 and covers the opening, and the

stator

11 is provided with a mounting hole. The

rotor

12 includes a connecting

shaft

121, and a first

rotating disk

122 and a second

rotating disk

123 disposed at opposite ends of the connecting

shaft

121. The connecting

shaft

121 and the mounting hole are rotatably sleeved, the first

rotating disc

rotating disc

123 is located outside the accommodating cavity, and the connecting

shaft

The sensor may be mounted to other equipment, such as unmanned aerial vehicles, unmanned vehicles, and ground-based remote control personnel, via the

housing

13 of the

motor

10.

Further, with continued reference to fig. 4 and 5, a wireless power supply assembly 30 is further disposed in the accommodating cavity, and the wireless power supply assembly 30 is electrically connected to the

rotating body

20. The wireless power supply assembly 30 is used to supply power to the

rotator

20. The wireless power supply assembly 30 is disposed in the

housing

13 of the

motor

10, so that the space occupied by the sensor can be further reduced. The wireless power supplying module 30 may be connected to an external power source through a cable, or the wireless power supplying module 30 may be electrically connected to the external power source in a wireless manner. For example, when the wireless power supply module 30 is connected to an external power source through a cable, the wireless power supply module 30 may be electrically connected to the cable through a coupler, the cable transmits power provided by the external power source to the wireless power supply module 30, and the wireless power supply module 30 wirelessly transmits the power to the

rotating body

20. Of course, the wireless power supply assembly 30 may also transmit power to other components of the sensor that require power.

In an implementation example, the wireless power supply module 30 includes a power transmitting terminal 31 and a power receiving terminal 32. The power transmitting terminal 31 is fixedly attached to the

housing

13. The power receiving terminal 32 is disposed on a side of the

first turntable

122 facing the power transmitting terminal 31, and is disposed opposite to the power transmitting terminal 31, and the power receiving terminal 32 is electrically connected to the

rotating body

20. The power transmitting terminal 31 is electrically connected to an external power source, for example, by a cable or wirelessly. The power transmitting terminal 31 may transmit power to the power receiving terminal 32 in a wireless manner. The power receiving terminal 32 is electrically connected to the

rotating body

20, receives the power transmitted from the power transmitting terminal 31, and provides the power to the

rotating body

20 to provide the power to the

rotating body

20. The power receiving terminal 32 may supply power to the

rotator

20 through a cable or supply power to the

rotator

20 through a wireless manner.

For example, the power transmitting end 31 includes, but is not limited to, a transmitting coil, and the power receiving end 32 includes, but is not limited to, a receiving coil, and power is transmitted between the transmitting coil and the receiving coil through wireless power supply. In one implementation, electrical energy is transferred between the sending coil and the receiving coil by electromagnetic induction. The transmitting coil is connected with an alternating current, and a current is generated on the receiving coil by electromagnetic induction, thereby transmitting electric energy from the electric energy transmitting terminal 31 to the electric energy receiving terminal 32. Alternatively, the electric energy may be transmitted between the electric energy transmitting terminal 31 and the electric energy receiving terminal 32 through magnetic resonance or other forms.

In one implementation, the power transmitting end 31 is fixedly connected to the

housing

13, and the power transmitting end 31 further includes a transmitting coil rack, which supports a transmitting coil, and is fixedly connected to the

housing

13. The power receiving end 32 is bonded or otherwise attached to the

first hub

122 by fasteners. Alternatively, the power receiving end 32 includes a receiving bobbin that supports the receiving coil, and the receiving bobbin is fixedly connected to the

first turntable

122. The sending coil and the receiving coil are arranged oppositely, the distance between the electric energy sending end 31 and the electric energy receiving end 32 is small, the transmission effect is good, and the influence of other parts is not easy to affect. As shown in fig. 5, the power transmitting end 31 may be located below the power receiving end 32, i.e., the power transmitting end 31 is located at a side of the power receiving end 32 away from the

second turntable

123. Alternatively, the power transmitting terminal 31 is located above the power receiving terminal 32, i.e., the power transmitting terminal 31 is located on the side of the power receiving terminal 32 close to the

second turntable

123.

It should be noted that, in the embodiment of the present invention, the power receiving end 32 rotates with the rotation of the

rotor

12 of the

motor

10, and the power transmitting end 31 is fixed. The power receiving end 32 is fixedly connected to the

rotor

12 of the

motor

10, and the

rotor

12 drives the power receiving end 32 to rotate, so that the power receiving end 32 and the

rotating body

20 rotate together, and the power receiving end 32 and the

rotating body

20 are electrically connected. In other embodiments, it is understood that the power receiving end 32 and the power transmitting end 31 may both rotate as the rotating

body

20 rotates. For example, the power input of the power transmitting terminal 31 itself is obtained by connecting with an external power source in a wireless manner, and the power transmitting terminal 31 may also rotate along with the rotation of the

rotating body

20, which is not limited in the embodiment of the present invention. In order to ensure that the electric energy can be continuously and stably transmitted between the electric energy receiving terminal 32 and the electric energy transmitting terminal 31 during rotation, in the embodiment of the present invention, both the electric energy receiving terminal 32 and the electric energy transmitting terminal 31 are substantially disc-shaped.

Further, with continued reference to fig. 4 and 5, in the embodiment of the present invention, the sensor further includes a wireless communication component, and the wireless communication component is electrically connected to the wireless power supply component 30 and the

rotating body

20, respectively.

In an implementable embodiment of the invention, the wireless communication component comprises a

first signal terminal

40 and a

second signal terminal

41. The

first signal terminal

40 and the

second signal terminal

41 are oppositely arranged, and the

first signal terminal

40 is in wireless communication connection with the

second signal terminal

41. For example, one way to achieve this is that the

first signal terminal

40 is used to send a control signal to the

second signal terminal

41, and the

second signal terminal

41 is used to send a radar data signal to the

first signal terminal

40. The

second signal terminal

41 wirelessly. The

second signal terminal

41 is connected to the signal processing module on the

rotating body

20, and transmits a control signal to the signal processing module to control the signal processing module. The signal processing module transmits the generated radar data signal to the

second signal end

41, the

second signal end

41 transmits the radar data signal to the

first signal end

40 in a wireless mode, and the

first signal end

housing

13 of the

motor

10, so that the space of the

housing

13 can be fully utilized, and the occupied space of the sensor can be further reduced. Meanwhile, the

first signal end

40 is divided into two parts, so that components on the

first signal end

40 can be distributed, the occupied space of the

first signal end

40 in the transverse direction is reduced, and the utilization of the space is facilitated. The first communication board 401 and the

first control board

402 can be connected by a cable or wirelessly. The

first signal terminal

40 wirelessly communicates with an external device and the

second signal terminal

41 via the first communication board 401, and processes signals via the

first control board

402. The first communication board 401 may implement wireless transmission of signals in the form of a wireless lan, bluetooth, microwave, or the like.

With continued reference to fig. 4 and 5, in an implementable embodiment of the present invention, the

second signal terminal

41 includes a

second communication board

411 and a second control board 412. The

second signal terminal

41 can be distributed, the occupied space of the

second signal terminal

The

second communication board

411 and the second control board 412 can be connected by a cable or wirelessly, and the

second communication board

411 and the signal processing module on the

rotating body

20 can be connected by a cable or wirelessly. The

second signal terminal

41 wirelessly communicates with the signal processing module and the

first signal terminal

40 on the

rotating body

20 through the

second communication board

411, and processes the signal through the second control board 412. The

second communication board

411 may implement wireless transmission of signals in the form of a wireless lan, bluetooth, microwave, or the like.

In the embodiment of the present invention, the

second signal terminal

41 rotates with the rotation of the

rotor

12 of the

motor

10, and the

first signal terminal

40 is fixed. In other embodiments, it is understood that the
