A lubricating oil guiding system for a motor includes an axial tube, a first bearing mounted in the axial tube, a second bearing mounted in the axial tube, at least one separating plate securely mounted to the inner periphery of the axial tube, and at least one auxiliary oil chamber defined between the first bearing, the separating plate, and the shaft for distributing lubricating oil to the first bearing and for storing, buffering, and guiding the lubricating oil. A shaft of a rotor extends through the first bearing, the second bearing, and the separating plate. The first bearing defines an oil circulating loop and the second bearing defines an oil circulating loop. The separating plate is located between the first bearing and the second bearing to avoid mutual interference between the oil circulating loop of the first bearing and the oil circulating loop of the second bearing.
