Abstract
The utility model relates to a double-water-cooling structure of a motor drive system. The double-water-cooling structure of the motor drive system comprises a shell; a lower part in shell is fixed to a motor rotor; an upper part in the shell is provided with a controller; the shell is internally provided with a water-cooling pipe, and two water-cooling pipes are provided, wherein a first water-cooling branch is wrapped around the motor rotor and the controller, and a second water-cooling branch is arranged inside a rotating shaft of the rotor; and the motor and the controller share a set of cooling water system, so as to reduce the size and weight of the system and the production cost. Compared with a conventional motor water-cooling scheme, the cavity is particularly arranged in the motor shaft; the cooling liquid is communicated within the cavity; and the double cooling is realized respectively outside the motor shaft and inside the motor shaft, so that the internal temperature of the motor can be effectively lowered and the failure probability when the motor is in use is effectively reduced.
