摘要： The disclosure provides a cooling device (CD) and a motor (100) having the same. The cooling device (CD) includes: a first cooling channel (10), a second cooling channel (20) and a third cooling channel (30); wherein the first cooling channel (10), the second cooling channel (20) and the third cooling channel (30) are arranged along an axial direction (D1) and connected in sequence, and the second cooling channel (20) further extends along a radial direction (D2).. The disclosure can satisfy requirements of heat dissipation for an end portion of the motor winding (53) (i.e., along the axial direction (D1)), radial and circumferential directions of the motor (100) and power devices on the motor driver (54), and can improve heat dissipation efficiency of an integrated motor driving system of the endwise integrated structure in a limited space, while decreasing an overall weight of the system and reducing cost.

摘要： A rotor unit, a rotor, and a motor structure. The rotor unit (100) comprises: a rotor lamination (101); a plurality of magnetic steel units (102) consisting of magnetic steels (103) and located on the rotor lamination (101); and hole structures (104) located in the magnetic steels (103). The rotor unit and a flow guide disc together form a rotor assembly. The motor structure comprising a special cooling channel is formed in combination with a hollow shaft and the hole structures. The structure can directly cool the magnetic steels, a rotor iron core, and an end portion of a stator winding at the same time, and has a good cooling effect.
