At present, the existing driving motor is generally matched and used in a mode of separating a motor from a driver, and the driving motor and the driver are connected through a motor power line and transmit signals. Taking a common stepping motor as an example, the stepping motor is usually connected to a driver through four motor power lines, and the driver controls the motor through the four motor power lines, such as start-stop, reverse, speed regulation or enable.
However, in this way, because a motor power line is needed to connect the motor and the driver, the wiring is relatively troublesome in operation, and in addition, too long wiring may cause interference in the signal transmission process, thereby affecting communication. Meanwhile, one motor is matched with one driver, so that the overall cost is high and the structural design is complex.
In view of the above, the present application is intended to provide a new solution to the above-mentioned technical problem, and the specific structure thereof will be described in detail in the following embodiments.

The driving circuit board 20 is configured to receive an external control signal and drive and control the motor 110 according to the external control signal; the external control signal may include any one of a steering control signal, an enable control signal, or a start/stop control signal. It is understood that the steering control signal is mainly used to control the steering of the motor 110, for example, the current direction is forward, and the steering of the motor 110 is changed to reverse direction to realize forward and reverse rotation after receiving the steering control signal. Similarly, the start-stop control signal is used to control the start-stop of the motor 110, and the enable control signal is used to enable the motor 110. It will be appreciated that the external control signal may also be other control signals, such as a speed control signal for adjusting the speed of the motor 110.
The integrated motor is designed by integrating the driving circuit board 20 which is originally externally arranged or needs to be connected with the motor through wiring with the motor body; the integrated driving circuit board 20 receives external control signals such as a steering control signal, an enable control signal, or a start/stop control signal, and then drives and controls the motor according to the external control signals, thereby controlling the motor. In addition, due to the integrated design, compared with the traditional method that the motor and the driver are connected through four motor power lines, the wiring of the motor is simplified, the phenomenon that the signal transmission process is interfered due to overlong wiring can be avoided, and meanwhile, through the integrated design, the corresponding use is simpler and more convenient.
In one embodiment, referring to fig. 2, the external control signal receiving and processing function is realized. The driving circuit board 20 of the present application may include a signal input module 210, a motor driving module 220, and a main controller 230.
The signal input module 210 is connected to the main controller 230, and the signal input module 210 is configured to receive the external control signal and output the external control signal to the main controller 230.

The main controller 230 is configured to receive the external control signal and output a motor driving signal according to the external control signal. Specifically, the external control signal may include any one of a steering control signal, an enable control signal, or a start/stop control signal. Therefore, the motor driving signal outputted by the main controller 230 may include a steering driving signal, an enable driving signal, or a start/stop driving signal.

Specifically, for example, the operating voltage provided by the power module 260 is 24V DC, the voltage obtained after the voltage reduction and conversion by the DC-DC conversion module 280 may be 3.3V DC, and the 3.3V DC supplies power to the main controller 230.
Further, as shown in fig. 2, the DC-DC conversion module 280 is further connected to the signal input module 210, and accordingly, the DC-DC conversion module 280 further provides the converted 3.3V direct current to the signal input module 210.

Based on this, the driving circuit board of the present application is further configured to collect speed data of the motor 110, and dynamically adjust the rotation speed of the motor 110 according to the speed data. That is, the drive circuit board of the present application can support an internal speed regulation function.

The other path outputs a stable low voltage of 3.3V after being converted by the DC-DC conversion module 280, and supplies power to the main controller 230 and the signal input module 210. The motor driving module 220 adopts a TMC2209 chip scheme, and the scheme adopts a new chopping technology in the low-speed running process of the motor 110, so that the mute effect is excellent in the running process of the motor 110.
The control part:
