摘要： A fan frame electrical connection structure includes a frame body. The frame body has a wind incoming side and a wind outgoing side. A bearing cup seat is disposed at the wind outgoing side. Multiple static blades and an enclosure static blade are integrally formed between the bearing cup seat and the frame body. A lead pin set is integrally enclosed in the enclosure static blade. The enclosure static blade has a static blade front edge and a static blade rear edge. The static blade front edge is directed to the wind incoming side and has a front edge arc. The static blade rear edge is directed to the wind outgoing side and having a rear edge arc. Accordingly, the assembling and manufacturing process of the fan can be automated and speeded and the fan can keep having its original property.

摘要： The present disclosure relates to a drain pump driving apparatus and a laundry treatment machine including the same. A drain pump driving apparatus according to an embodiment of the present disclosure includes a controller configured to drive a motor, during drainage, based on an output current and a direct current (DC) terminal voltage with a first power when a lift is at a first level and to drive the motor with the first power when the lift is at a second level that is greater than the first level, wherein the lift is a difference between a water level of a water introduction part through which water flows into a drain pump and a water level of a water discharge part through which the water is discharged out of the drain pump. Accordingly, water pumping can be performed smoothly even if the lift is changed during the drainage.
