In the external gear set synchronous motor, the number of the first gear and the second gear is two.

In the external gear set synchronous motor, two sides of the mounting base plate are bent outwards to form fixing lugs of an integrated structure, and fixing screw holes are formed in the fixing lugs.

Compared with the prior art, this external gear train synchronous machine has following advantage:

1. the output shaft and the motor shaft are mutually parallel and are connected and driven through the gear set, and the gear set is positioned outside the motor body, so that the height of the motor is further reduced, and the motor is convenient to mount in the table plate of the low-thickness mahjong table;

2. the transmission ratio between the motor shaft and the output shaft is convenient to change, the output gear is positioned on the output shaft, the number of teeth of the output gear is changed by only opening the cover plate, and the adjustment is more convenient.
