[0018] A specific embodiment of this utility model provides a frequency conversion integrated hoist, combined with the attached... Figure 1 As shown, it mainly includes a frequency converter 1 and a hoist 2. The frequency converter 1 is fixedly mounted on the drive motor 3 of the hoist 2. This fixed mounting method of the frequency converter 1 and the hoist 2 can avoid damage to the separate frequency converter during transportation. Furthermore, this mounting method can shorten the connection length between the frequency converter and the hoist, and even integrate the connection directly into the housing, which can further avoid problems such as short circuits and open circuits.

[0019] In a specific embodiment of this application, the frequency converter 1 includes a heat sink 4 and a control component. One end of the heat sink 4 is connected to the drive motor 3, and the other end is connected to the control component. Thus, the control component is mounted on the drive motor 3 through the heat sink 4, and the heat sink 4 is used to dissipate heat from the control component.

The brake controller 7 is integrated with the frequency converter 1, that is, the brake controller 7 and the frequency converter 1 are disposed in the same housing and both are disposed on the heat sink 4. The brake resistor 8 is connected to the brake controller 7.

[0022] In some embodiments, the braking resistor 8 is disposed outside the frequency converter 1. This external placement of the braking resistor 8 facilitates heat dissipation. Specifically, the braking resistor 8 can be disposed below the drive motor 3.
