A motor and its blade unit include a blade unit made of a conical fundamental body and a plurality of blades formed around the surface of the conical fundamental body. The blades of the blade unit are multi-sectioned ones of different sizes. These blades increase water flowing speed with help of the centrifugal force produced by rotating of the blade unit, and quickly guide water to flow along the outer wall of a motor and out of the motor, not to flow reversely back to a shaft. At the same time these blades can cut impurities in water preventing the motor from clogged by impurities, increasing water flowing-out speed, lowering motor load and electricity consumption and saving motor horsepower to prolong its service life, and also possible to be combined with various types of motors for extensive use.
