It can be understood that in other embodiments, the transition portion 621b may be omitted, and the hollow portion 621a is directly connected to the base portion 621c.

Please refer to FIG. 4 to FIG. 12, the first connector 630 is used to electrically connect the motor 400 and the electronic governor 600. Specifically, the first connector 630 includes a first conductive member 631 and a first packaging member 632. The first conductive member 631 is electrically connected to one end of the three-phase line 810. The first conductive member 631 may be made of conductive materials such as copper, copper alloy, aluminum alloy, conductive plastic, and conductive rubber. The first conductive member 631 is encapsulated in the first packaging member 632, and the first conductive member 631 is at least partially exposed from the first packaging member 632.

The first conductive member 631 includes a conductive ring and a joint part. The conductive ring is fixedly connected to the joint part. In this embodiment, the conductive ring and the joint are integrally formed. It can be understood that, in other embodiments, the conductive ring and the joint portion may also be independent components. In this case, the conductive ring and the joint portion may be fixed by welding or the like.

The conductive ring has a first through hole 631c for the first fastener 641 to pass through. For example, when the first fastener 641 is a screw, the stud of the first fastener 641 may pass through the first through hole 631c and be electrically connected to the circuit board 620, and the nut of the first fastener 641 may be electrically conductive The side of the ring facing away from the circuit board 620 resists to be electrically connected to the conductive ring. The joint part is used to electrically connect the conductive coil and the three-phase line 810.

The first packaging member 632 is used to encapsulate the first conductive member 631, and the first packaging member 632 may also encapsulate part of the three-phase line 810. In the process of manufacturing the first package 632, the connected three-phase line 810 and the first conductive member 631 can be fixed together in the injection mold, and the first package 632 can be obtained by injection molding and other processes. The first package 632 may be made of an insulating material, for example, the material of the first package 632 may be plastic. The overall shape of the first package 632 may be square, round, trapezoidal, etc., which is not limited herein. When the motor 400 and the circuit board 620 are connected, the first package 632 may be disposed on the first housing 611.

The first package 632 has a third surface 632a, a fourth surface 632b and a first connection portion 632c that are disposed opposite to each other. In this embodiment, the first connection portion 632c penetrates the third surface 632a and the fourth surface 632b, and the fourth surface 632b is disposed toward the first housing 611. The first connection portion 632c includes a first opening 632d and a second opening 632e that communicate with each other. The conductive ring is provided at the connection between the first opening 632d and the second opening 632e, and both the first opening 632d and the second opening 632e communicate with the first through hole 631c. When installing the first connector 630, the fourth surface 632b of the first package 632 may be combined with the second surface 611e of the first housing 611. Specifically, it may be that the fourth surface 632b of the first package 632 abuts on the second surface 611e of the first housing 611. The first fastener 641 penetrates the first opening 632d, the first penetration hole 631c, the second opening 632e, and the first through hole 611a to electrically connect the first conductive member 631 and the circuit board 620.

As a preferred embodiment, at least part of the first conductive member 631 may be exposed from the first connecting portion 632c to allow the first fastener 641 to be installed on the first connecting portion 632c and electrically connect the first conductive member 631 and Circuit board 620. Specifically, the conductive ring may be exposed from the first opening 632d. The first opening 632d may be formed on the third surface 632a, and the second opening 632e may be formed on the fourth surface 632b. The cross-sectional size of the first opening portion 632d is larger than the cross-sectional size of the second opening portion 632e, and the cross-sectional size of the first opening portion 632d is adapted to the maximum cross-sectional size of the first fastener 641. When the first fastener 641 is a screw, the size of the first opening 632d can just accommodate the head of the screw, while the second opening 632e cannot provide a housing space for the screw head. Therefore, when the user needs to install the first connector 630, only the first connector 630 is connected to the fourth surface 632b and the second surface 611e of the first housing 611, and the first opening portion near the third surface 632a is exposed In this state, the user can securely connect the first connector 630 to the first housing 611 through the first fastener 641. Therefore, the first connector 630 ensures that the motor 400 and the electronic governor 600 are connected according to a predetermined connection mode, preventing the user from installing the first connector 630 upside down.

In this embodiment, the first fastener 641 is a screw. In some embodiments, after the first fastener 641 is installed in place, the head of the first fastener 641 can all be received in the first opening 632d without protruding from the third surface 632a. It can also be determined whether the first fastener 641 protrudes from the third surface 632a to determine whether it is correctly installed and installed in place.
