The invention discloses a same-cavity liquid-cooled middle-mounted motor which comprises a shell, a middle shaft, a stator assembly and the like, wherein the middle shaft penetrates through the shell and extends out of the shell, the stator assembly is sleeved in the rotor assembly and is connected to the shell, a clutch is respectively connected with the middle shaft and a gear speed change mechanism, a control system is connected with the stator assembly, the middle separator divides the interior of the shell into a first cavity and a second cavity, the middle shaft penetrates through the middle separator, the gear speed change mechanism penetrates through the middle separator and is connected with the rotor assembly, the stator assembly, the control system and other components are arranged in the first cavity, and the gear speed change mechanism and other components are arranged in the second cavity. According to the invention, the control system is arranged in the first cavity, and is closer to the core component of the motor in space, so that more accurate control and monitoring can be realized. The control system and the stator assembly are arranged together and then concentrated for heat dissipation by using the insulating cooling liquid, and the improvement of the heat dissipation efficiency is facilitated. |
