As shown in fig. 1 and fig. 2, a direct drive gate machine includes a machine base 1, an outer rotor motor 2 and a gate 4.

The motor rotating shaft of the outer rotor motor 2 is fixedly connected with the base 1; the gate 4 is fixedly connected with the casing of the outer rotor motor 2.

Specifically, in this embodiment, the casing is provided with a holder, and then the shutter 4 is fixed to the holder by bolts.

Specifically, in the present embodiment, the outer rotor motor 2 is mounted on the base 1 in a vertically downward manner, i.e., as shown in fig. 1.

Specifically, in this embodiment, the outer rotor motor 2 is a servo motor. Preferably, a dc brushless servo motor is used.

In order to further realize the accurate control of the motor, the motor can be provided with an encoder, the motion position of the swing door can be accurately captured through the encoder, so that the swing door is controlled by the controller, the accurate control of the door opening angle is realized, and the doorpost drives the code disc to synchronously rotate when rotating, thereby realizing the positioning of the swing door.

Specifically, in this embodiment, in order to keep the external rotor motor 2 in a vertically mounted state, the following mounting structure is adopted between the external rotor motor 2 and the machine base 1: firstly, a mounting plate and an auxiliary plate 5 are fixedly arranged on a machine base 1; the motor rotating shaft 21 penetrates through the auxiliary plate 5 and is fixedly connected with the mounting plate. The mounting plate and the auxiliary plate 5 simultaneously limit the mounting position of the motor rotating shaft 21, and the auxiliary plate 5 ensures that the motor rotating shaft 21 is in a vertical state, because if the limitation of the auxiliary plate 5 on the motor rotating shaft 21 is lacked, the motor rotating shaft 21 is easily inclined after being fixedly connected with the mounting plate, and the motor rotating shaft 21 is ensured to be in a vertical state by adding the auxiliary plate 5.

Specifically, in this embodiment, a bearing 51 is disposed in the through hole of the auxiliary plate 5, and the motor shaft 21 passes through the bearing 51. There is no rotational fit between the motor shaft 21 and the auxiliary plate 5, but after the bearing 51 is provided, it is ensured that the motor shaft 21 is now in a vertical installation state with respect to the auxiliary plate 5, and the motor shaft 21 is prevented from tilting with respect to the auxiliary plate 5.

During operation, the outer rotor motor 2 drives the casing to rotate, and the casing drives the flashboard 4 to rotate, so that the flashboard 4 is controlled to be opened and closed.

The floodgate of this embodiment adopts outer rotor servo motor direct drive flashboard 4 to do the motion of opening and shutting, has avoided the trouble that the speed reducer wearing and tearing and speed reducer and being connected of motor lead to the core to produce completely, has avoided the influence of other trouble of speed reducer itself to the core reliability, increases the core reliability, can increase substantially the life of core, reduces substantially core manufacturing cost simultaneously, the noise that can also greatly reduced core operation produced.
