Problems solved by technology
[0003] Liquid-cooled motors need to adopt a special liquid-cooled casing, and make liquid cooling channels in the casing, so the size of the casing is usually large; at the same time, because the liquid cooling channels in the casing are criss-crossed and complex, the reliability of the casing is improved. Difficulty in design and manufacture increases the loss of manpower and material resources and is expensive, which is not conducive to reducing the cost of the entire motor

Embodiment Construction
[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0041] Such as figure 1 As shown, a liquid-cooled stator core, the outer wall of the stator core 1 includes several straight grooves and several curved grooves, the groove depth of the straight grooves and curved grooves is smaller than the wall thickness of the stator core 1 .
[0042] The several straight grooves are all parallel to the axis of the stator core 1 and arranged at intervals from each other. Preferably, several straight grooves are arranged at equal intervals. Several curved grooves connect all the straight grooves end to end to form a cooling channel 15; the two ends of the cooling channel 15 are separated from each other and not connected.
[0043] In this embodiment, the bottom surfaces of the straight groove and the curved groove are located on the same cylindrical surface, and the axis of the cylindrical surface is the ax...

A liquid-cooled stator core relates to the technical field of motors. The outer wall of the stator core comprises a plurality of straight grooves and a plurality of bent grooves, and the groove depths of the straight grooves and the bent grooves are smaller than the wall thickness of the stator core; the plurality of straight grooves are parallel to the axis of the stator core and are arranged at intervals; all the straight grooves are communicated end to end through the bent grooves to form a cooling channel; the head and tail ends of the cooling channel are separated. The invention also discloses a motor comprising the liquid-cooled stator core, the motor comprises a casing, the stator core is fixedly arranged in the casing, and the inner wall of the casing seals the cooling channel. According to the liquid-cooled stator iron core and the motor, the stator iron core is ingenious in processing, and the manufacturing process is simple; and the cooling channel is arranged on the outer wall of the stator core, so that the heat dissipation and cooling efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a liquid-cooled stator core and a motor. Background technique [0002] With the rapid development of motors, the heat dissipation requirements of motors are getting higher and higher. Traditional natural cooling and air cooling cannot meet the heat dissipation requirements of motors. More efficient liquid cooling is used instead. However, liquid-cooled motors that use liquid cooling for heat dissipation have the following disadvantages: [0003] Liquid-cooled motors need to adopt a special liquid-cooled casing, and make liquid cooling channels in the casing, so the size of the casing is usually large; at the same time, because the liquid cooling channels in the casing are criss-crossed and complex, the reliability of the casing is improved. Difficulty in design and manufacture increases the loss of manpower and material resources, and is expensive, which is not conducive to reduc...
