[0055] Please refer to Figures 1-8 A motor cylindrical casing comprises a casing 1, a partition table 11 is arranged in the casing 1, and the casing 1 is divided into a first mounting cavity 12 and a second mounting cavity 13 under the action of the partition table 11, and the first mounting cavity 12 and the second mounting cavity 13 are respectively connected with the outer end of the casing 1.

[0076] The surface of the partition table 11 is also provided with a glue reduction position 14 coaxially distributed with the transmission groove 15;

[0077] The inner ends of the plurality of reinforcing ribs 111 extend in the glue reduction position 14, and through the design of the glue reduction position 14, the problem of shrinkage caused by too thick plastic injection molding is prevented;
