a control box fixed at the rear end of the DC brushless motor;
a control board located within the control box, the control board having a temperature sensor; and
and the brushless frequency converter is arranged on the control board and is electrically connected with the direct current brushless motor so as to adjust the voltage of the direct current brushless motor.
Preferably, the control box is fixed to a rear end of the dc brushless motor by screws.
Preferably, a bracket is further included.
Preferably, the dc brushless motor is fixed to the bracket.
Preferably, the dc brushless motor is fixed to the bracket by screws.
Preferably, the brushless frequency converter regulates the voltage of the dc brushless motor from 380V to 220V.

The specific implementation mode is as follows:
the following describes in further detail embodiments of the present invention with reference to the accompanying drawings.
Fig. 1 shows a block diagram of a drive device according to the invention. Fig. 2 shows an exploded view of a drive device according to the invention. Referring to fig. 1 and 2, the driving apparatus 1 includes a dc brushless motor 10, a control box 11, a control board 12, and a brushless inverter 13. The control box 11 is fixed to the rear end of the dc brushless motor 10, and the other end of the dc brushless motor 10 corresponding to the rear end is provided with a shaft 101. In this embodiment, the control box 11 is fixed to the dc brushless motor 10 by screws. The control board 12 is located in the control box 11, and a temperature sensor (not shown) is disposed on the control board 12 for sensing the temperature of the external environment. The brushless inverter 13 is also disposed on the control board 12 and electrically connected to the dc brushless motor 10. In this embodiment, the dc brushless motor 10 is fixed on a bracket 14 and can be fixed by screws 15. The temperature sensor can sense the temperature of the external environment, when the temperature of the external environment is low, the temperature sensor can sense and send a signal to the brushless frequency converter 13, and then the brushless frequency converter 13 adjusts the voltage of the dc brushless motor 10 to be reduced, for example, from 380V to 220V, accordingly, the rotation speed of the fan of the dc brushless motor 10 is reduced, and thus, energy can be saved.
The utility model has the advantages that: the brushless frequency converter is applied to the direct current brushless motor, the change of the external temperature is sensed through the temperature sensor, and therefore a signal is sent to the brushless frequency converter to enable the brushless frequency converter to adjust the voltage of the direct current brushless motor, and finally the fan rotating speed of the direct current brushless motor is controlled, the purpose of saving energy is achieved, and meanwhile the protection to the environment can be improved.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
