This invention relates to the field of motor technology, specifically to an oil-immersed motor and its usage method. The motor includes a base, a housing fixed to the upper side of the base, a front cover and a rear cover enclosing the front and rear sides of the housing, and a rotating shaft rotatably mounted in the middle of the housing, the front cover, and the rear cover. Multiple first lateral oil ports are distributed on the rotating shaft, allowing for lateral spraying during shaft rotation. Combined with the rotation of two opposing turbine blades mounted on the shaft, this uplifts and throws out the oil from the lower part of the housing, promoting axial relative flow of the oil. Simultaneously, the longitudinal oil ports on the two turbine blades spray the oil longitudinally, achieving a multi-directional and uniform distribution of cooling oil to the internal components of the housing. In other words, the rotation of the shaft achieves both lateral and relative axial spraying of the oil, while also pushing the lower part of the oil within the housing relative to each other, thereby significantly improving the oil distribution range and cooling effect.
