Frequency conversion integrated machine

A frequency conversion integrated machine (100), comprising: a frequency converter (110) used for performing frequency conversion on inputted alternating current, and outputting the alternating current; an electric motor (120) used for receiving the alternating current that is converted and outputted by the frequency converter (110), so as to drive the rotating shaft of the electric motor (120) to rotate; and a speed reducer (130) comprising: an input end (131) connected to the rotating shaft of the electric motor (120), so as to rotate along with the rotating shaft; an output end (132) that rotates at a rotating speed lower than the rotating speed of the input end (131); and a transmission device (133) arranged between the input end (131) and the output end (132), and used for transmitting the power of the input end (131) to the output end (132), and reducing the rotating speed of the output end (132) relative to the rotating speed of the input end (131). According to the frequency conversion integrated machine (100), by means of a special assembling mode, the output end can drive a load without being connected to devices such as a through cylinder, a coupling, and a hydraulic coupler, and thus, the present invention has the advantages of being small in occupied space, low in cost, convenient to install and maintain, and the like.
